Properties of high-strength concrete can vary significantly depending on the specific raw materials used and the strength levels attained. Data on these characteristics are needed by agencies such as departments of transportation that must consider construction alternatives with various materials and develop plans on the basis of economics as well as engineering properties. Results are presented of a study to determine the properties of high-strength concrete producedwith several sets of materials. These materials represent those used in structures built under north carolina department of transportation control. Data obtained included compressive strength, creep, shrinkage, elastic modulus, modulus of rupture, and splitting tensile strength of high-strength concrete produced from a variety of sourcesand types of materials. Rudimentary cost coparisons were also made. This paper appears in transportation research record no. 1284, Cement, admixtures, and concrete 1990.
