Abstract

Abstract

The splitting tensile method for the tensile strength of concrete is usually used in structural applications, so it is great important in the investingating the relation between the direct tensile strength and the splitting strength. But there lationship between the splitting strength and the direct tensile strength is not consensus confirmed at home and abroad. In order to obtain the exact results, the experimental apparatus for concrete of the direct tension are designed, which resolves the difficulty of ensuring that the load is truly axial. Tests of the direct tension are performanced on three different concrete mixes( C20, C40, C60) at 3, 7, 14, 28 and 60 days, and the test data do not scatter. The relations between the tensile strength and the cube compressive strength are obtained, and a formula for investigating the relation between the direct tensile strength and the splitting strength are proposed
- premixed concrete,
- cubic compressive strength,
- direct tensile strength,
- splitting strength,
- early ages
