The Mechanical Properties of Lightweight Concrete under Different Factors

Abstract:

By choosing domestic ceramsite as lightweight aggregate, mixing with active mineral admixture (fly ash) and the water reducing agent, and adopting the method of absolute volume to design the three ceramsite concretemixture ratio, 27 groups, 243 lightweight aggregate ceramsite concrete test cubes of 100mm×100mm×100mm are obtained for compressive strength test, and the physical and mechanical properties of the aggregate are studied. At the same time, through the systematic test, the influences of the aggregate strength, water-binder ratio, fly-ash content, etc on ceramsite concrete are studied. Finally the best mixture ratio scheme for ceramsite concrete is gained, providing theoretical basis for the application of lightweight aggregate concrete.
