- Abstract
The stress-strain relationship and tensile resistance parameters of polyvinyl alcohol fiber reinforced cementitious composite(PVA-ECC) are studied and analyzed experimentally by uniaxial tensile test. The specimens are 200mm×50mm×20mm with different fly ash content. The test is carried out by using displacement controlled test installation and complete stress-strain curves are obtained. The results show that with the increase of fly ash content, the concrete strength and average crack spacing show a trend of decrease after the first increase, the tensile strain increases gradually and the maximum value is 6.23%, the average crack width decreases gradually. In this experiment the best fly ash content is 70%. If the drop of compressive strength of ECC is permit, increasing fly ash content appropriately will help to further improve the toughness and ductility of PVA fiber reinforced cementitious composite.
