Preparing Technique of Super High StrengthHigh Performance Concrete with Superfine Sand

With the understanding that there will be a great demand for superhigh performance concrete (SHPC) in the future construction engineering,while the resources of coarse and intermediate sand commony used for SHPC are scarce,so it is very important to replace coarse and intermediate sand by plentiful superfine one; First in China and abroad as well a superfine sand superhigh performance concrete with max. slump 255mm and max.28d compressive strength 126.8 MPa was prepared.It was compared with superhigh performance concrete with intermediate sand.
