      <title>SWEDISH R &amp; D PROGRAM ON HIGH-PERFORMANCE CONCRETE</title>
      <link>https://trid.trb.org/View/468313</link>
      <description><![CDATA[A consortium of six companies and two governmental research funding organizations are carrying out a six-year research and development program on high performance concrete in Sweden. In mid-1994, half the program time has been completed. The program focuses on research directed towards the understanding of mechanisms and subsequent modeling and experimental verification. It also includes application and oriented research aiming at the establishment of technical relationships. This should further lead to practical recommendations and guidance for use in specific projects or product and process development within the industry.]]></description>

      <title>UNITED STATES GOVERNMENT'S ROLE IN HIGH-PERFORMANCE MATERIALS FOR INFRASTRUCTURE</title>
      <link>https://trid.trb.org/View/468314</link>
      <description><![CDATA[Sixteen agencies of the U.S. Federal Government have developed an interagency proposal for promoting the use of high performance concrete and other materials for use in the Nation's Infrastructure. They are working jointly with the Civil Engineering Research Foundation (CERF) to enlist private sector support for sponsoring a research and development program aimed at getting the materials into use. CERF is drawing upon the technical community, such as that in ACI to define the various research needs and studies which will lead to materials acceptance. Materials other than concrete are addressed in other parts of the total program. Workshops were held in the spring and fall of 1993 to develop schedules and priorities. Tentative cost for the concrete program is approximately $200 million over 10 years.]]></description>

      <title>HIGH-PERFORMANCE CONCRETE: THE ROLE OF THE CEMENTITIOUS MATERIALS MODELING LABORATORY</title>
      <link>https://trid.trb.org/View/468315</link>
      <description><![CDATA[The CMML is described and two examples -- setting and diffusivity -- of the progress being made in simulating the behavior of portland cement pastes are presented. They illustrate the use of digital-image-based models to represent the microstructures of this class of materials and to investigate aspects of their engineering performance. Some other simulations are mentioned briefly. The CMML and the techniques developed in it are helping to clarify the relationships between microstructure and engineering properties that need to be understood if high-performance concrete and other cement-based materials are to have a sound basis in materials science.]]></description>

      <title>TENSILE PROPERTIES OF HIGH-PERFORMANCE CONCRETE</title>
      <link>https://trid.trb.org/View/468316</link>
      <description><![CDATA[Properties of high-strength concrete under uniaxial states of stress are studied. Main emphasis was given to tensile, compressive and fracture properties of concrete with compressive strengths ranging from 6000 to 12,000 PSI. Complete stress-deformation curves under uniaxial tension were obtained using a close-loop servo-hydraulic testing system. Important mechanical and fracture properties such as moduli of elasticity, fracture energy, Gf, and the critical crack tip opening displacements, Wc are evaluated from the experimental results. Fracture energies were evaluated from the descending branch of stress-crack separation curves using the direct tension test results. For the range of high-strength concretes studied, experimental results indicate that the relationship between tensile and compressive strengths are different from those of normal strength concretes.]]></description>

      <title>CANADIAN EXPERIENCE IN PRODUCING AND TESTING HPC</title>
      <link>https://trid.trb.org/View/468317</link>
      <description><![CDATA[Making and using high-performance concrete necessitate the implementation of a strong and efficient quality control program on the materials used to make the concrete, on the properties of the fresh and hardened concrete, and on the placing and curing techniques in order to be sure of obtaining a high performance final product. Testing high performance concrete necessitates great care and special attention.]]></description>

      <title>HIGH-PERFORMANCE CONCRETE IN THE U.S. ARMY CORPS OF ENGINEERS</title>
      <link>https://trid.trb.org/View/468319</link>
      <description><![CDATA[In 1970, when confronted with the problem of severe abrasion-erosion damage in stilling basins below dams, a solution was found in the development of concretes having strengths greater than 100 MPa. This was done using silica fume and high-range water-reducing admixtures. Similar and higher-strength high-performance concretes have also been developed for defense purposes as part of the protective-structures portion of the U.S. military research and development (R&D) program. When stronger concrete or concrete that must resist a more severe exposure is needed, the Corps of Engineers' concrete R&D capability has been able to develop it, and it probably will continue to be able to do so.]]></description>

      <title>HIGH-PERFORMANCE CONCRETE: SUPERIOR MICROSTRUCTURE FOR LONG-TERM DURABILITY</title>
      <link>https://trid.trb.org/View/468323</link>
      <description><![CDATA[This paper discusses recent research on high performance concrete with a focus on cementitious materials designed for durability. A major key to such performance originates with the concrete microstructure. A high packing density coupled with adequate processing and cement binder characteristics makes possible the formation of a fine microstructure. In turn, this fine microstructure results in a low permeability and therefore provides a resistance to aggressive forces from the environment, which together enhance its long term durability. The favorable interaction among physical and chemical phenomena gives rise to better long term performance, whether the application is structural, or chemical, such as in waste management.]]></description>

      <title>PROPERTIES OF HIGH-PERFORMANCE FLY ASH CONCRETE</title>
      <link>https://trid.trb.org/View/468325</link>
      <description><![CDATA[In this study, two types of fly ash, dry and wet bottom ashes of different particle size distributions, were used. Physical and chemical properties of these fly ashes were tested and compared with the original feed fly ashes received directly from the utility. The effects of these fly ashes on the strength of concrete were studied when used as 15, 25, 35, and 50 percent cement replacement by weight of cement. The results show that fly ash, when proportioned properly, can enhance the properties of concrete. The chemical composition of fly ash of different particle size distributions varies slightly. For fly ash with large particle size distribution, the fly ash concrete reaches only 85 percent of the control concrete strength at the age of 180 days.]]></description>

      <title>HIGH-STRENGTH AND HIGH-PERFORMANCE CONCRETE IN KOREA</title>
      <link>https://trid.trb.org/View/468306</link>
      <description><![CDATA[Recent developments concerning research on and application of high-strength, high-performance concrete in Korea are reported in this paper. In 1990, the Department of Construction initiated the building of 2 million housing units in five new satellite cities around Seoul and mandated some taller buildings to properly shape the skylines of the new satellite cities. Since this project requires apartment buildings up to 30 stories high, the technical necessity of using high-strength, high-performance concrete suddenly draws attention. In 1994, the Department of Construction initiated two research projects for a two-year period as the first phase of a research program. One of the projects is on improving concrete performance. Concrete performance is further divided into three groups: high strength concrete, durable concrete and flowing concrete.]]></description>
