Indirect Tensile Strengths of Crushed-Sand Concretes in Correlation with Its Compressive Strength

The correlation between indirect tensile strengths and compressive strengths of the crushed-sand concretes was experimentally investigated. The crushed-sand concrete called in this paper was termed as the concrete using crushed-sand to replace traditional river sand in producing concrete. Six types of the crushed-sand concretes were examined with different compositions. The indirect tensile test included three-point bending test and cylinder splitting test as follows: dimensions of bending specimen was 100×100×300 mm (width×depth×span-length) while that of splitting specimen was 100×200 mm (diameter×length). The compressive test was used cube specimen of 150×150×150 mm. The testing results were obtained then comparatively evaluated.
