Abstract: Based on the tests of five groups of polyvinyl alcohol fiber reinforced engineered cementitious composite (PVA/ECC) specimens, the creep performance of PVA/ECC with different fiber contents under pressure was studied in this paper. The results show that the incorporation of PVA fibers can lower density and elastic modulus of substrate materials and lead to a decline of capacity of resistance to creep. Additionally, within 0-2vol% of volume fraction of PVA fiber, the large or small volume fraction of PVA fiber is found to increase the creep coefficient of PVA/ECC, and the medium volume of PVA fiber can decrease the creep coefficient. The creep speeds of specimens all have a character that increasing rapidly at the initial and then increasing slowly, the creep amount in initial 7 days is about 40% of total amount, that in initial 60 days is about 80% of total amount, and creep amount gradually gets convergent after 60 days. Based on the result of regression analysis to the experimental data, the calculation models of creep coefficient and creep degree of PVA/ECC were presented.
