【摘要】 <正>To develop high ductility cementitious composites(HDCCs)for repairing hydraulic discharge structures,the effect of water-binder ratio,polyvinyl alcohol(PVA)fiber content,and fly ash content on the tensile properties of HDCCs was studied.The results show that with increase in water-binder ratio and/or fly ash content,the ultimate tensile strain of HDCC increases gradually,while the ultimate tensile更多还原
