      <title>Tuning the electrolyte formulation from flame-retarding to nonflammable for safe and high-performance SiO and high nickel-based cells</title>
      <link>https://trid.trb.org/View/2647943</link>
      <description><![CDATA[Electrolyte and interface design for employment of Si-containing anode and high-nickel cathode in high-energy density lithium-ion batteries (LIBs) is a significant challenge, owing to their high interfacial reactivity, resultant performance fade, and risk of safety hazard. Improving the battery safety using current conventional electrolyte relies on phosphazene-type flame-retardant additive, but often with sacrificed performance, which urgently requires innovative electrolyte solutions that simultaneously satisfy both performance and safety. Herein, we report a nonflammable electrolyte (NF EL) formulation customized for Si and high-nickel based LIBs, being composed of methyl(2,2,2-trifluoroethyl) carbonate (FEMC), 1 M LiPF₆ salt and limited amount of FEC additive. This electrolyte formulation simultaneously enhances the stability of solid electrolyte interphase (SEI) and cathode electrolyte interphase (CEI) with F-enriched species, reduces cell swelling, suppresses crack and enables exceptional long-term stability in industrial 1.2 Ah pouch cells, validated by 82 % capacity retention after 500 cycles under aggressive conditions (1C, 4.35 V, 45 °C). Battery safety is significantly enhanced, as verified by superior thermal stability in hot-box test and suppression and a substantial delay of thermal runaway in accelerating rate calorimetry (ARC) result. This work gives insight into electrolyte and interface engineering for safe and high-performance LIBs, and electric vehicles and e-mobilities.]]></description>

      <title>An experimental investigation on geotechnical properties of a clayey soil stabilised with lime and zeolite in base and subbase courses</title>
      <link>https://trid.trb.org/View/2047391</link>
      <description><![CDATA[Zeolite is often exploited to reduce the consumption of lime in the treatment of problematic clays and to help further enhance the soil stabilisation process in pavement base and subbase courses. For the mix design of the proposed pavement materials, 8% lime was first opted, according to pH tests, as the optimum content and its different portions were then replaced by zeolite inclusion. A comprehensive set of Atterberg limits, standard Proctor, unconfined compression and unconsolidated undrained (UU) triaxial tests was performed on lime and zeolite stabilised specimens. Zeolite addition into the mixture increased the maximum dry unit weight and decreased the optimum moisture content. The least plasticity index and the highest unconfined compressive strength were attained at 25% of lime replacement with zeolite, deemed to be the optimum mixing content. Results of UU triaxial tests on the optimum mixtures also confirmed the marked improvement of shear strength parameters.]]></description>

      <title>Influence of Spot Welding Parameters on Al-Si Coated 22MnB5 for Automotive Application</title>
      <link>https://trid.trb.org/View/1560390</link>
      <description><![CDATA[The application of press hardening steels (PHS) Al-Si coating has been increasing in body in white vehicles as an approach to meet the demands of safety and CO2 reduction regulations. The vehicle structures with PHS largely depend on the integrity and the mechanical performance of the spots weld. During the spot welding process, intermetallic phase may appear in function of the chemical composition of the steel and coating. One of these intermetallics is the Fe-Al phase which brittleness decreases the strength of the weld joint. In this study, resistance spot welding (RSW) experiments were performed in order to evaluate the influence of the welding parameters of single-lap joints PHS - 22MnB5 steel grade. Welded samples of the Al-Si coated PHS steel as received, i.e., before any heat treatment and stamping, were evaluated by means of glow discharge optical emission spectroscopy (GDOES) technique that allows a quick and accurate evaluation of the chemical composition profile along the spot weld thickness. The GDOES results showed that the squeeze welding parameter has the higher influence on cupper diffusion at the Al-Si-Fe layer. The pre-burn current and welding current showed the higher influences in Fe-Al diffusion. The pulse technique and post-heat treatment had had the lower influences in Fe-Al diffusion.       ]]></description>

      <title>Utilization and Properties of Road Thermal Resistance Aggregates into Asphalt Mixture</title>
      <link>https://trid.trb.org/View/1591479</link>
      <description><![CDATA[To improve the road performance and heat resistance of thermal resistance aggregates, thermal resistance aggregates wrapped with organosilicon resin were prepared. The optimal surface treatment process of different thermal resistance aggregates was determined. The surface wrapping effect of different thermal resistance aggregates were evaluated based on the macropore structure and microsurface morphology. In addition, the road performance of different thermal resistance aggregates before and after surface treatment were compared and analyzed. The heat resistance performance of different thermal resistance asphalt mixtures was tested by an indoor sunlight simulation test. Furthermore, the effect of surface treatment on road performance and heat resistance of a thermal resistance asphalt mixture was evaluated. The results showed that the surface treatment of shale ceramsite with organosilicon resin achieved the best result. The 24 h oil absorption decreased to 2.05%. The surface pore sealing rate was as high as 78.3%, and the opening pores could hardly be seen in the SEM images. After being surface treated with organosilicon resin, the water absorption, crushing value and abrasion value of three kinds of thermal resistance aggregates decreased by 82.87%–94.50%, 6.8%–22.07% and 10.87%–28.56%, respectively, and their adhesion increased to grade 5. The surface treatment of thermal resistance aggregates could significantly improve the high temperature performance and water stability of thermal resistance asphalt mixtures. There was little effect on the low temperature performance, while the heat resistance performance of the thermal resistance asphalt mixture was improved to varying degrees.]]></description>

      <title>Paste Hydration of Beta-Dicalcium Silicate, Tricalcium Silicate, and Alite</title>
      <link>https://trid.trb.org/View/1488865</link>
      <description><![CDATA[The chemistry of hydration in pastes of ß-dicalcium silicate, tricalcium silicate and an alite as functions of water-solids ratio and fineness of the silicate have been investigated at 25 C.  The CaO/SiO₂ ratio of the stable tobermorite gel hydration product was found to increase as the water-solids ratio decreased, but was not appreciably influenced by the fineness of the original unhydrated silicate.  Heat of solution data were obtained and heat of hydration values calculated.  The effects of surface area, CaO/SiO₂ ratio, and water content were considered in the calculation.  The calculated values of the surface energy and the heat of hydration of tobermorite gel were in good agreement with previously obtained values.  Heats of hydration were calculated for hypothetical reactions producing dry tobermorite gel of composition C₁, ₅SH and having a specific surface area of 300 m²/g.  The values obtained were 11.6 cal/g C₂S, 81.1 cal/g C₂S, and 77.0 cal/g alite.]]></description>

      <title>IN SITU MONITORING OF THE HYDRATION PROCESS OF K-PS GEOPOLYMER CEMENT WITH ESEM</title>
      <link>https://trid.trb.org/View/744251</link>
      <description><![CDATA[Geopolymers are amorphous three-dimensional alumino-silicate binder materials; geopolymer cement can be a strong candidate for substituting Portland cement applied in the fields of civil, bridge, pavement, hydraulic, underground, and military engineering.  Environmental scanning electron microscope (ESEM) is an advanced microscopy technique that has the capability of observing continuous reacting processes (without pretreatment on the surface of a sample).  This article reports on a study in which ESEM was used in situ to quantitatively study the hydration process of K-PS geopolymer cement under an 80 percent RH environment.  An energy dispersion X-ray analysis (EDXA) was also employed to distinguish the chemical composition of hydration product.  The ESEM micrographs showed that metakaolin particles pack loosely at 10 minutes after mixing, resulting in the existence of many large voids.  As hydration proceeds, a lot of gels were seen and gradually precipitated on the surfaces of these particles.  At later stage, these particles were wrapped by thick gel layers and their interspaces were almost completely filled (the microstructure of the geopolymer paste became denser).  Well-developed crystals were not found in K-PS geopolymer cement bulk paste at any point, while spongelike amorphous gel is always observed.  The authors note that the molar ratios of K/Al increase while Si/Al decrease with the development of hydration.]]></description>

      <title>SILICATE OF SODA AS A SOIL STABILIZING AGENT</title>
      <link>https://trid.trb.org/View/122474</link>
      <description><![CDATA[EXPERIMENTS WERE CONDUCTED WITH CLAY MINERALS AND SOILS TO DETERMINE THE EFFECTS OF LIQUID SODA SILICATE AS A SOIL STABILIZING AGENT. DRY AGING IN THE LABORATORY FOR A PERIOD OF 30 DAYS AND 5 AND ONE-HALF MONTHS DID NOT ALTER THE CRUSHING RESISTANCE OF ANY OF THE CLAY-BRIQUETTES. THIS INDICATES THAT ANY REACTION BETWEEN THE CLAY MINERALS AND SILICATE OF SODA TAKES PLACE IN A MOIST CONDITION. AGING IN ANY MOIST ATMOSPHERE USUALLY IMPROVED THE PROPERTIES OF THE CLAY-SILICATE MIXTURES. RESULTS FROM THE CLAY MINERALS STUDY SUGGEST THAT: (1) BENEFICIAL RESULTS COULD BE EXPECTED FROM TREATING KAOLINITIC SOILS WITH SILICATE OF SODA, (2) FAVORABLE REACTIONS MAY RESULT FROM TREATING SOILS WITH COLLOIDAL COMPLEX OF ILLITIC MATERIAL WITH SILICATE OF SODA, AND (3) IF THE COLLOIDAL COMPLEX OF A SOIL IS COMPOSED LARGELY OF MONTMORILLONITIC MATERIAL, TREATMENT WITH SILICATE OF SODA WILL MOST LIKELY BE DETRIMENTAL TO THE STABILITY OF SUCH A SOIL. THE RESPONSE OF CECIL CLAY TO SILICATE OF SODA WAS VERY SIMILAR TO THAT OF KAOLINITE AND HALLOYSITE. THIS WAS EXPECTED BECAUSE THE COLLOIDAL FRACTION OF CECIL CLAY HAS BEEN IDENTIFIED AS KAOLINITIC IN NATURE. THE RESPONSE OF WOOSTER AND CLERMONT SILT LOAMS TO SMALL ADDITIONS OF SILICATE OF SODA SUGGEST THAT THE MECHANICAL MAKEUP OF THE SOIL (PROPORTIONS OF SAND, SILT AND CLAY), MIGHT ALSO BE AN IMPORTANT FACTOR IN DETERMINING THE RESPONSE OF THE SOIL TO TREATMENT WITH SILICATE. DATA INDICATE BOTH WITH SOIL AND CLAY MINERALS THAT THE SILICATE OF HIGH SILICON OXIDE LOW SODIUM OXIDE CONTENT GAVE THE MOST FAVORABLE RESULTS.]]></description>

      <title>HIGH-STRENGTH LIGHTWEIGHT CONCRETE MADE OF POROUS AGGREGATES FROM INDUSTRIAL WASTE</title>
      <link>https://trid.trb.org/View/100434</link>
      <description><![CDATA[AGLOPORITE, WHICH IS MANUFACTURED BY THE CONTACT SINTERING OF CLAY MATERIALS AND INDUSTRIAL WASTES ON SINTERING MACHINES, IS USED AS A LIGHTWEIGHT AGGREGATE FOR CONCRETE MIXES. AGLOPORITE HAS A RELATIVELY SIMPLE PRODUCTION FLOWSHEET AND IS ONE OF THE MOST EFFICIENT TYPES OF POROUS AGGREGATES. THE PRINCIPAL STARTING MATERIAL IS ZAGLIK ALUNITE. DURING PROCESSING, THE ORE YIELDS 50 PERCENT WASTE IN THE FORM OF SAND AND MUD FRACTIONS CONTAINING ABOUT 80 PERCENT SILICON OXIDE. A TRIAL BATCH OF AGLOPORITE POROUS AGGREGATES WAS OBTAINED AND A RESEARCH PROGRAM ON ITS MANUFACTURE WAS STARTED. THE PROPERTIES OF AGLOPORITE WERE STUDIED AND THE RESULTS ARE TABULATED. AGLOPORITE WAS USED IN THE MANUFACTURE OF STRUCTURAL LIGHTWEIGHT CONCRETES OF STRENGTH EQUAL TO OR GREATER THAN 400 KG PER SQUARE CENTIMETER. FOR CONCRETES OF BRAND 300 AND 400, CONSUMPTION OF BRAND-400 CEMENT DOES NOT EXCEED 400 AND 500 KG PER CUBIC METER OF CONCRETE MIX, RESPECTIVELY. FOR CONSTRUCTIONAL AGLOPORITE CONCRETE, THE DESIGNERS SUGGEST THE FOLLOWING PARTICLE-SIZE DISTRIBUTION AGGREGATE: SAND, 33-35 PERCENT; CRUSHED MATERIALS OF SIZE 50-10 MM, FROM 20 TO 25 PERCENT BY VOLUME; CRUSHED MATERIALS OF SIZE 10-20 MM, FROM 35 TO 40 PERCENT BY VOLUME. THE SPECIFIC WEIGHT OF THE CONCRETE AND THE SELECTION OF THE COMPOSITION FOR THE MIX OF HIGH STRENGTH AGLOPORITE CONCRETE IS DISCUSSED. RECENT STUDIES INDICATE THE POSSIBIL- ITY OF FURTHER REDUCING THE BULK WEIGHT OF AGGREGATE WITHOUT REDUCING ITS STRENGTH.]]></description>

      <title>THE INFLUENCE OF LIMESTONE AGGREGATES UPON THE ROAD CEMENT CONCRETE CHARACTERISTICS</title>
      <link>https://trid.trb.org/View/485294</link>
      <description><![CDATA[The use of aggregates of limestone for production of road cement concrete leads to numerous technical and economic advantages.  Romania owns large limestone resources spread over the entire surface of the country.  Based on the results of petrographical, minerological and chemical analysis and on the physical and mechanical tests done on different limestone types from 12 quarries and also, based on the results obtained on concrete produced with the limestone, characteristics necessary for production of cement concrete for use in highway pavement were established.  This paper presents some of the laboratory and field test results.]]></description>

      <title>A STUDY CAMPARING THE SCALING RESISTANCE OF AIR-ENTRAINED CONCRETE WITH CONCRETE CONTAINING A SILICONE ADMIXTURE</title>
      <link>https://trid.trb.org/View/98636</link>
      <description><![CDATA[THE LABORATORY UNDERTOOK AN INVESTIGATION TO COMPARE THE SCALING RESISTANCE TO FREEZE-THAW ACTION AND THE COMPRESSIVE STRENGTH OF AIR-ENTRAINED CONCRETE WITH CONCRETE CONTAINING A SILICONE CONCRETE ADMIXTURE. FOUR BEAMS WERE MADE AND TESTED FOR FLEXURAL STRENGTH IN THE FIELD. TWELVE PRISMS WERE MADE IN THE FIELD AND TESTED IN THE LABORATORY FOR SCALING RESISTANCE, WEIGHT LOSS, AND CHANGE IN LENGTH. TWENTY-FOUR CYLINDERS WERE MADE IN THE FIELD AND TESTED IN THE LABORATORY FOR COMPRESSIVE STRENGTH. THE CONCRETE CONTAINING THE SILICONE ADMIXTURE REACHED FINAL SET FROM THIRTY TO THIRTY-SIX HOURS AFTER PLACEMENT. ITS FLEXURAL STRENGTH WAS FOUND TO BE SLIGHTLY HIGHER AFTER TWENTY-EIGHT DAYS THAN THAT OF THE AIR-ENTRAINED CONCRETE. THE COMPRESSIVE STRENGTH OF THE ADMIXTURE CONCRETE WAS FOUND TO BE APPROXIMATELY 11 PER CENT HIGHER AFTER THIRTY DAYS, 14 PER CENT HIGHER AFTER NINETY DAYS, AND 15 PER CENT HIGHER AFTER ONE YEAR THAN THE COMPRESSIVE STRENGTH OF THE AIR- ENTRAINED CONCRETE. NO DIFFERENCE WAS FOUND IN THE SCALING RESISTANCE BETWEEN THE TWO TYPES OF CONCRETE UP TO APPROXIMATELY 800 CYCLES. HOWEVER, BEYOND THAT NUMBER OF CYCLES, THE ADMIXTURE CONCRETE WAS FOUND TO HAVE A SLIGHTLY HIGHER RESISTANCE TO SCALING FROM THE EFFECTS OF FREEZE-THAW ACTION. NO DIFFERENCE IN LOSS OF WEIGHT OR INCREASE IN LENGTH COULD BE DETERMINED BETWEEN THE TWO TYPES OF CONCRETE DUE TO THE FREEZE-THAW ACTION. /AUTHOR/]]></description>

      <description><![CDATA[AT THE END OF 1965, THE LABORATORY X-RAY QUANTOMETER WAS DEVELOPED. THIS MODEL HAS 6 X-RAY SPECTRUM CHANNELS OF A FIXED TYPE AND 5 INDEPENDENT INTERCHANGEABLE CALCULATING CHANNELS. THIS PERMITS QUANTITATIVE ANALYSIS OF 5 OUT OF 6 CHEMICAL ELEMENTS: CALCIUM, IRON, SILICON, ALUMINUM SULFUR AND POTASSIUM OR THEIR OXIDES. THIS METHOD OF ANALYSIS WAS DEVELOPED FOR THE RAW MIXTURES. IT IS POSSIBLE TO DETERMINE THE CONTENT OF CALCIUM OXIDE AND IRON OXIDE IN 7-10 MINUTES, AND A COMPLETE CHEMICAL ANALYSIS FOR ALUMINUM OXIDE, SILICON DIOXIDE, CALCIUM OXIDE, AND IRON OXIDE IN 12-15 MINUTES. X- RAY SPECTRUM ANALYSIS WITH A QUANTOMETER OBTAINS AS GOOD RESULTS AS ANALYTICAL CHEMISTRY ANALYSIS AND ACHIEVES RESULTS VERY RAPIDLY. /AUTHOR/]]></description>

IN FAVORABLE CASES, THE DEGREE OF CONDENSATION OF THE DISSOLVED SILICIC ACID CAN BE DETERMINED BY A KINETIC METHOD BASED ON THE RATE OF FORMATION OF THE MOLYBDATOSILICIC ACID COMPLES. WHERE A COMPLEX DISTRIBUTION OF ANION SIZES EXISTS, E.G., IN CALCIUM SILICATE HYDRATE GELS, THE METHOD DOES NOT GIVE ABSOLUTE RESULTS, THOUGH IT CAN BE USED TO FOLLOW CHANGES IN THIS DISTRIBUTION. /AUTHOR/]]></description>

      <description><![CDATA[The presence of invisible contaminants on apparently clean surfaces has been shown to be detrimental to subsequent paint performance and is responsible for increases in hull roughness and fuel consumption of tankers. The authors describe colorimetric, potentiometric and conductimetric techniques that make it possible to identify contaminants and measure their concentration on blast-cleaned steels. A new development in the evaluation of inorganic zinc silicate paints in cargo/ballast tanks is also discussed. This is a potentiometric test that is capable of assessing in situ the amount of active free zinc remaining in a coating, and hence, enables the estimation of the useful life of the coating.]]></description>
