Abstract

A comprehensive experimental study was carried out to investigate the engineering properties of high strength concrete in the range of 10,000 to 15,000 psi. The study included the determination of the uniaxial compressive strength, static modulus of elasticity, tensile strength, flexural strength, stress distribution parameters and Whitney block assumption and temperature rise of high strength concrete due to chemical reaction. The concrete was produced by using silica fume, locally available aggregate, cement type I, superplasticisers and retarders. Three concrete mix designs were obtained from ready recipes and tests were carried out at six different ages. Test results were compared with ACI code formulas for predicting modulus of elasticity and modulus of rupture for low strength concrete by using uniaxial compressive strength . Also, results were compared with existing data concerning the modulus of elasticity for high strength concrete and the tensile strength for low strength concrete. Experimental results are presented and discussed along with SHORT AND LONG TERM PROPERTIES OF HIGH STRENGTH CONCRETE: previously established relations for relations for normal strength concrete. Recommendations and conclusions are made for different relations and measurements.
