Abstract

Abstract

Engineered cementitious composite(ECC) can significantly improve the seismic performance and durability of concrete structures, which has pseudo strain hardening and multiple cracking performances.Through 32 groups of 192 specimens for doing orthogonal test of compressive strength of ECC, it was studied the cube compression failure process, and further research on water-binder ratio, fiber content by volume, fly ash content and sand-binder ratio on the size effect of ECC cube compressive strength.The test results show that as PVA fiber content increases, ECC compressive toughness is improved obviously;water-binder ratio and fiber content are the main factors which affect the ECC compressive strength and size effect.When water-binder ratio increases, the compressive strength of ECC materials decreases and size effect coefficient increases.Fiber content increases, the compressive strength of test block increases and the size effect coefficient increases.The bending tests show that the fiber content by volume increases, the ECC flexural strength of the composite increases obviously.
