摘要：

This　paper　presences　the　influence　of　coarse　aggregate-space　coefficient　on　the　rheological　properties　of　self-compacting　concrete　(SCC).　The　results　indicate　that　coarse　aggregate-space　coefficient　has　significant　influence　on　slump　flow　and　V-funnel　flow　time　of　SCC,　when　the　maximum　aggregate　particle　size　is　16mm　and　the　volume　ratio　of　sand　and　motor　is　0.43,　meanwhile　water　binder　ratio　is　0.38.　The　higher　the　coarse　aggregate-space　coefficient,　the　lager　the　slump　flow,　the　shorter　the　V-funnel　flow　time.　The　range　of　coarse　aggregate-space　coefficient　of　SCC　is　suitable　for　1.31∼1.58　under　the　condition　of　the　paper.　The　suitable　range　can　guarantee　excellent　rheological　properties　and　stability　of　SCC　mixture.　There　is　little　effect　of　coarse　aggregate-space　coefficient　on　compressive　strength　in　this　paper　tests.　©　(2015)　Trans　Tech　Publications,　Switzerland.
