Abstract:
This paper presents the results of over 6000 tests to investigate the mechanical properties (compressive strength, modulus of elasticity, and tensile strength) of high-strength concrete (HSC). Material variables included total amount and composition of cementitious material; type and brand of cement; type and brand of superplasticizer; and coarse aggregate type, source, size, and gradation. Both heat- and moist-curing conditions were investigated. The heat-curing process emulated that used in precast plants. The experimental results are compared with code relations and proposed equations for HSC. Based on the results of these tests, recommended relationships are given.
