PVA-ECC; Creep; Shrinkage; DPDM.Abstract
The creep behaviors of prepared PVA-ECC materials(fiber content 1.5%) and normal concrete were tested through stress creep test at a stress level of 35%, along with a shrinkage test during early age(0-28d). Results indicate that PVA-ECC material exhibits lower shrinkage and a creep coefficient 1.45 times higher than that of normal concrete with the same strength at early age.
