摘要：

The　effects　of　sand-to-cementitious　materials　ratio　(S/C),　water-to-cementitious　materials　ratio　(W/C),　fiber　species　and　using　a　reduction　additive　on　the　shrinkage　distortion　of　fiber-reinforced　high-ductility　cementitious　composites　(ECC)　were　investigated.　Experimental　results　show　that　the　shrinkage　strain　of　ECC　reduces　with　increasing　S　C　and　enlarges　with　increasing　W/C.　Chinese　PVA　fibers　effectively　control　the　early　stage　shrinkage　distortion　of　ECC,　but　Japanese　PVA　fibers　of　high　Young＇s　modulus　have　great　effect　on　the　final　stage　shrinkage　distortion　of　ECC.　Hybrid　fibers　can　better　control　the　shrinkage　distortion　of　ECC　than　Chinese　or　Japanese　PVA　fibers　separately　when　the　W/C　is　0.40.　The　shrinkage　strain　probably　reduces　200×10-6　by　using　a　reduction　additive,　and　the　reduction　additive　can　also　effectively　control　the　shrinkage　distortion　of　ECC　at　the　W/C　of　0.40.
