      <title>SLURRY WALLS SUCCEED IN BOSTON</title>
      <link>https://trid.trb.org/View/269827</link>
      <description><![CDATA[The use of slurry walls as permanent load-bearing elements could get a big boost in the U. S.  from the Massachusetts Bay Transportation Authority's (MBTA) experience in building a 3.2-mile subway extension.  More than 600,000 sq ft of slurry wall has been installed to hold platforms and roofs in three of the four new stations at the Cambridge end of the Boston area transit system's Red Line.  The $574-million project claims a U. S.  record - 14,800 lin ft of continuous slurry trench wall in a cut-and-cover tunnel.  The slurry trench walls are in a variety of soils, including glacial till and rock, mixed face granular material and soft clay. A Federal Highway Administration test program indicates that the construction has worked well.]]></description>

      <title>GOOD PROSPECTS FOR CONCRETE ON ROADS</title>
      <link>https://trid.trb.org/View/269407</link>
      <description><![CDATA[The author makes a survey of the various concrete products which can be obtained from ready-mix plants.  It is stated that the interest in these products has increased partly because of the rising price of bitumen, and partly because both suppliers and buyers are more interested in quality.  A new handbook "Concrete on the ground" will be published in the spring of 1985.  (Author/TRRL)]]></description>

      <title>LABORATORY EVALUATION OF FLY ASH AND OTHER POZZOLANS FOR USE IN CONCRETE PRODUCTS</title>
      <link>https://trid.trb.org/View/99114</link>
      <description><![CDATA[STUDIES OF BINDERS FOR ATMOSPHERIC-PRESSURE STEAM- AND AUTOCLAVE-CURED CONCRETE PRODUCTS HAVE EMPLOYED A VARIETY OF METHODS FOR COMPACTING LABORATORY SPECIMENS, WHICH MAY BE FORMED FROM PASTES, MORTARS, OR CONCRETES. MORTARS MADE WITH STANDARD OTTAWA GRADED SAND ARE SHOWN TO PROVIDE A SATISFACTORY BASIS FOR COMPARING PORTLAND CEMENT POZZOLAN BINDERS FOR USE WITH RELATIVELY NONREACTIVE AGGREGATES, BUT REQUIRE CORRECTION FOR THE DEPRESSING EFFECT ON AIR CONTENT OF SUCH POZZOLANS AS FLY AS HAVING MODERATE TO HIGH CARBON CONTENTS. MORE ACCURATE DATA FOR BINDER FORMULATION ARE PROVIDED BY MORTARS WHICH INCLUDE THE FINER FRACTIONS, PASSING THE NO. 30 OR NO. 50 SIEVE, OF POTENTIALLY REACTIVE AGGREGATES USED IN STEAM-CURED CONCRETE PRODUCTS. THE FINER FRACTIONS INCLUDE THE REACTIVE PORTIONS OF SUCH AGGREGATES AS SAND, BURNED CLAY OR SHALE, SINTERED FLY ASH, SLAG, PUMICE, GRANITE, AND OTHERS. A METHOD OF THIS STUDY EMPLOYS PLASTIC MORTARS WITH CONSISTENCY CONTROLLED BY USE OF THE FLOW TABLE, AND WITH BINDER--FINE AGGREGATE RATIOS EQUIVALENT TO THOSE OF THE CONCRETE PRODUCTS BEING DEVELOPED. TYPICAL STRENGTH DATA FOR ATMOSPHERIC-PRESSURE STEAM-CURED AND AUTOCLAVED MORTARS ARE PRESENTED, SHOWING THE EFFECTS OF VARIATIONS IN CEMENT--POZZOLAN RATIO, CEMENT AND POZZOLAN COMPOSITION, AND AGGREGATE TYPE. /AUTHOR/]]></description>

      <title>BENDING MOMENT IN BRIDGE SLABS DUE TO WHEEL LOADS</title>
      <link>https://trid.trb.org/View/84191</link>
      <description><![CDATA[A design office procedure for determining the induced live-load bending moment in a concrete bridge slab is presented.  The procedure provides longitudinal and transverse bending moments at the centerline of the slab resulting from any pattern of vehicle tires.  Empirical equations are used to determine effects of wheels at the slab centerline, and moment contour maps are used for wheels remote from this point.  The procedure compares well with analytical and experimental results obtained by others.  The effect of wheel overloads on the long-term serviceability of concrete bridge slabs is also discussed.]]></description>

      <title>THE STATUS OF CEMENT AND CONCRETE R AND D IN THE UNITED STATES</title>
      <link>https://trid.trb.org/View/150893</link>
      <description><![CDATA[Data presented show that the level of research and development (R&D) in the cement and concrete industry in the United States is inadequate to meet current needs and future challenges. Specific areas of concern are identified, and various incentives for and barriers to R&D are discussed. Emphasis is placed on the need for a vigorous, coordinated basic research and development establishment (civilian, academic, and governmental) coupled with an efficient mechanism for technology transfer to commercial practice. This mature industry is moving slowly to enlarge and improve its physical plant and increase its production efficiency but is doing little to learn more about its products. Foreign developments are used as examples of what can be done with proper planning and adequate capital outlays. Recommendations are made where specific efforts are required for economic, institutional, and technological improvement. These include some nontechnical suggestions, such as increasing governmental and industrial support for R&D and reexaming some of the barriers to R&D caused by legislative restraints on vertical integration and lack of tax incentives. Technical issues identified are the need for an interdisciplinary approach to experimental, theoretical, and modeling studies; an increase in studies of basic mechanisms of cement hydration and development of strength in concrete and in studies of long-term durability under extreme environments; and the efficient utilization of energy and resources by the industry. An independent research and development facility is suggested as one way to get the proper nucleus of people together to examine critically various industry-wide problems of immediate and long-range concern.]]></description>

      <title>PRODUCTION METHODS AND WORKABILITY OF CONCRETE</title>
      <link>https://trid.trb.org/View/472332</link>
      <description><![CDATA[Compiled on the basis of the RILEM conference on production methods and the workability of concrete held in Glasgow, U.K. in 1996, the anthology deals with the manufacturing of both ordinary and high-performance concretes and their chemical properties in different environments. According to the editors, proper concrete mixing is essential in achieving cost-effective construction. The book is divided into nine sections, covering such topics as superfluid, sprayed and precast mixing; rheology; and test methods.]]></description>

      <title>FREEZE-THAW DURABILITY OF HIGH-PERFORMANCE CONCRETE MASONRY UNITS</title>
      <link>https://trid.trb.org/View/464900</link>
      <description><![CDATA[A high-performance concrete masonry unit (CMU) was developed to replace the standard 38-lb (17.2-kg) unit used in modern construction.  High-performance units were produced from several different trial mixes.  This paper presents the results of tests conducted to determine the durability of the new units as compared to standard normal-weight CMUs.  The units were tested for absorption and for freeze-thaw durability.  High-performance units that were made with normal-weight aggregates had somewhat lower absorption rates than standard units, but the freeze-thaw durability was reduced.  High-performance units produced with lightweight aggregates had absorption results comparable to standard normal-weight units. The freeze-thaw durability of these units varied, and for some, it was superior to that of standard normal-weight units.  Admixtures were used in some mixes to increase durability and lower absorption.  A lightweight mix that used a waterproofing admixture to precoat the aggregate before mixing resulted in the most durable units under freeze-thaw testing.  These units also had very low absorption rates.]]></description>

      <title>CONCRETE MEETS MULTIPLE BRIDGE NEEDS</title>
      <link>https://trid.trb.org/View/485854</link>
      <description><![CDATA[This article explains why concrete is the material of choice for bridge construction, particulaly high-performance concrete. Concrete strengths of 5,000 to 9,000 psi are easily attainable with local materials and it can be a maintenance free material -- if it is not painted. It can be cast in any shape or form and is long-lasting when properly designed and detailed.]]></description>

      <title>SULFUR CONCRETE FOR PRECAST PRODUCTS</title>
      <link>https://trid.trb.org/View/477431</link>
      <description><![CDATA[A research program aimed at overcoming the problems of durability in sulfur concrete (SC) as experienced by other researchers, was undertaken in 1972 by the author in cooperation with the National Research Council of Canada and McGill University. These problems were generally associated with the instability of the sulfur modifier used in the sulfur cement. After some three years of intensive research and development by the author's company, a process was developed by which a proprietary polymer additive (SRX tm, now called STX tm) was used to control the crystallization of elemental sulfur on cooling from the molten state. The first SC manufacturing plant began production of precast products in Calgary, Alberta, in 1975. This article presents previously unpublished information on the extent to which SC has been used in the production of precast products and emphasizes benefits of SC compared to other concretes for such application.]]></description>
