      <title>PROPERTIES OF HIGH-STRENGTH CONCRETE CONTAINING LIGHT-, NORMAL-, AND HEAVYWEIGHT AGGREGATE</title>
      <link>https://trid.trb.org/View/366284</link>
      <description><![CDATA[The results are presented of a study of the influence of density of aggregate on mechanical properties of high-strength concrete.  The materials used and the experimental details are described, and the results are discussed.  Lightweight concretes and heavyweight concretes were studied.  A comparison of the experimentally determined values of the elastic modulus with the calculated values according to the relationships recommended by the ACI Building Code, the British Standard Code, and the Norwegian Standard Code, showed that all codes overestimated the elastic modulus of high-strength heavyweight concrete.  In general, the magnitude of drying shrinkage was inversely proportional to the period for which specimens were water cured.  These and other study findings are discussed.]]></description>

      <title>HYDROGEN EVOLUTION FROM FERROPHOSPHOROUS AGGREGATE IN PORTLAND CEMENT CONCRETE</title>
      <link>https://trid.trb.org/View/101908</link>
      <description><![CDATA[HYDROGEN EVOLUTION IN A HEAVY CONCRETE CONTAINING FERROPHOSPHORUS AGGREGATE WAS NOTED DURING CONSTRUCTION OF A BIOLOGICAL SHIELD FOR A NUCLEAR GENERATING STATION. WHILE THE REACTION WAS OF A SELF-LIMITING NATURE, THE CONCRETE WOULD PRODUCE OVER 25 TIMES ITS VOLUME OF HYDROGEN BEFORE THE REACTION CEASED. THE FACTORS AFFECTING THE REACTION AND THE POSSIBLE MECHANISMS INVOLVED ARE DISCUSSED. SUBSEQUENT INVESTIGATION HAS SHOWN THAT A SIMILAR REACTION OCCURS WITH FERROSILICON, ANOTHER HEAVY-WEIGHT SLAG, OTHERWISE OF POTENTIAL VALUE IN HEAVY CONCRETE. /AUTHOR/]]></description>

      <title>STANDARD PRACTICES FOR SELECTING PROPORTIONS FOR NORMAL, HEAVYWEIGHT, AND MASS CONCRETE (ACI 211.1-91)</title>
      <link>https://trid.trb.org/View/362700</link>
      <description><![CDATA[This publication, describes, with examples, two methods for selecting and adjusting proportions for normal weight concrete, both with and without chemical admixtures, pozzolanic, and slag materials.  One method is based on an estimated weight of the concrete per unit volume; the other is based on calculations of the absolute volume occupied by the concrete ingredients.  The procedures take into consideration the requirements for placeability, consistency, strength, and durability.  Example calculations are shown for both methods, including adjustments based on the characteristics of the first trial batch.  The proportioning of heavyweight concrete for such purposes as radiation shielding and bridge counterweight structures is described in an appendix.  This appendix uses the absolute volume method, which is generally accepted and is more convenient for heavyweight concrete.  An appendix provides information on the proportioning of mass cocnrete.  The absolute volume method is used bsecause of its general acceptance.]]></description>

      <title>DETERMINING THE STATIC AND DYNAMIC PROPERTIES OF HARDENED NORMAL WEIGHT AND HEAVY WEIGHT CONCRETE</title>
      <link>https://trid.trb.org/View/288203</link>
      <description><![CDATA[This paper describes a method for determining the material constants of normal weight and heavy weight concrete under static and dynamic loading at 7, 28, and 90 days.  The tests were conducted at the University of California, Structures and Materials Laboratory, Berkeley, CA, for comparing the compressive strength, modulus of elasticity, Poisson's ratio, and static tensile strength of normal weight and heavy weight concrete for a nuclear power plant.]]></description>

      <title>CONCRETE. STRUCTURE, PROPERTIES AND MATERIALS</title>
      <link>https://trid.trb.org/View/273357</link>
      <description><![CDATA[This 3-part book is intended as a text for Civil Engineering students.  The first part covers the properties of hardened concrete.  Terms are defined, and the significance and origin of each property and controlling factors are set forth.  The second part of the book deals with the production of concrete.  Separate chapters present current information on the composition and properties of commonly used cements, aggregates, and admixtures.  One chapter describes the principles underlying the proportioning of concrete at an early age and how they influence the operations to which freshly produced concrete is subjected. Quality assurance programs are also briefly discussed.  The third part of the book reviews advances in concrete technology resulting from innovations to adapt the material for special engineering applications.  Information on composition, properties, and applications of several types of special concrete is provided including structural lightweight concrete, heavyweight concrete for nuclear shielding, high-strength concrete, high-workability concrete, shrinkage-compensating concrete, fiber-reinforced concrete, concretes containing polymers, and mass concrete.]]></description>

      <title>HEAVY DUTY PAVEMENTS IN INTERLOCKING CONCRETE</title>
      <link>https://trid.trb.org/View/146846</link>
      <description><![CDATA[It is pointed out that because of the elegant appearance of interlocking concrete paving blocks the structural benefits are not always remembered.  Some of these are the hardness of the surface together with strength and durability. Additionally ground settlements which would damage cast in-situ materials can be readily accommodated and the interlocking concrete block can be relevelled, repaired or even relocated with negligible additional material cost. The features of interlocking concrete paving are described and the benefits due to the ease of laying are noted.  A brief note is made on applications.  The article also deals with design of the paving with the aid of a design chart showing the required cover thickness for various traffic loads. Subbase requirements are also discussed again with reference to design charts.  The author concludes that with increasing demand and volume the economics of interlocking paving are likely to become increasingly favourable. (TRRL)]]></description>

      <title>SPECIAL CONCRETE</title>
      <link>https://trid.trb.org/View/87819</link>
      <description><![CDATA[The Central Laboratory of Strabag Bau-AG has controbuted on several occasions towards the development of various special concretes.  These are cement concretes to which special additives or admixtures have been added or with peculiarities in the manufacturing process or for special applications.  A few of the wide ranging developments are described in the following examples.  (1) eps concrete (expanded polystyrene concrete) known by its trade names styropor- or hostapor-concrete with qualities of increased thermal insulation and light weight.  Its range of applications include industrial buildings, railways and highway construction.  Typical eps concrete structures are named for each of the different uses (tank construction, track foundations, road bases) and these can be referred to in practice.  (2) lightweight concrete for higher constructional stability requirements; preparation methods for lightweight additives have been developed and in the aptitude tests reference has been made not only to the normal density of the hardened lightweight concrete.  (3) heavyweight concrete with a density of over 2.6 kg/m3 for use in nuclear reactors against radiation and as ballast concrete; the central laboratory is involved in the preparation of specifications for the manufacture of these. (4) plastic concrete, which deviates in certain respects from standards which have been laid down and which has been improved by Strabag Bau-AG (Experience with the burglangenfeld demonstration project).  Furthermore, descriptions are provided of pre-heated concrete, particularly in projects at Berlin and Hamburg, hardened concrete, with which Strabag Bau-AG has been systematically involved for over 30 years and the lift-slab method of construction. /TRRL/]]></description>

      <title>RECOMMENDED PRACTICE FOR SELECTING PROPORTIONS FOR NO-SLUMP CONCRETE</title>
      <link>https://trid.trb.org/View/140111</link>
      <description><![CDATA[This standard is intended as a supplement to ACI Standard "Recommended Practice for Selecting Proportions for Normal and Heavyweight Concrete (ACI 211.1-74)." The standard describes a procedure for proportioning concretes having slumps in the range of zero to 1 in. and consistencies below this range, for aggregates up to 1 1/2 in. maximum size. Suitable equipment for measuring such consistencies is described. Tables similar to those in ACI 211.1-74 are provided which, along with laboratory tests on physical properties of fine and coarse aggregate, yield information for obtaining concrete proportions for a trial mixture. Examples of the use of these tables, in conjunction with tables in ACI 211.1-74 are given. An appendix provides complete conversion of all tabular data to metric system units and shows a sample problem worked out with metric values.]]></description>
