DIRECT TENSILE STRENGTH OF CONCRETE AND HYDRATED CEMENT PASTE WITH AND WITHOUT CALCUIM CHLORIDE

The effects of calcium chloride on the direct tensile strength of hardened cement paste and concrete cylindrical and prismatic specimens are investigated. Two different techniques for the determination of the direct tensile strength i.e. Cylinders with embedded bars and prisms with glued end blocks are used. The results indicate that the addition of 2% calcium chloride significantly increases the direct tensile strength and the dynamic modulus of hardened cement paste. It is concluded that the addition of calcium chloride can partially inhibit the drying-shrinkage and sorption induced microcracking in the concrete system. (A) /TRRL/
