摘要：

In　order　to　improve　the　strength　of　crumb　rubber　powder,　this　paper　presents　an　experiment　on　the　influence　of　redispersible　polymer　powder　and　superplacticister　on　the　strength　of　Crumb　Rubber　Mortar　(CRM).　The　function　mechanism　of　superplacticister　and　redispersible　polymer　powder　on　CRM　were　also　discussed.　The　test　results　show　that　in　this　experiment,　there　is　certain　improvement　of　strength　properties　of　CRM　by　redispersible　polymer　powder,　and　composite　superplacticister　and　redispersible　polymer　powder　have　great　effect　on　the　strength　of　CRM.　The　test　data　also　show　that　the　size　of　rubber　has　great　effects　on　the　strength　of　CRM,　which　indicated　there　are　the　best　size　of　crumb　rubber　filler　particles.
