摘要
结合普通自密实混凝土固定砂石体积法与全计算法配制了密度小于1 950 kg/m3的SCLC60混凝土,通过V形漏斗、流动扩展度、L槽、U形槽、筛分、柱分层及表面沉降试验对SCLC60自密实轻骨料混凝土的流动性、变形性、填充性和抗离析性进行了评价,结果表明:所配制的SCLC60满足自密实混凝土的工作性能要求。
Mix proportions of SCLC60 of which densities are less than 1 950 kg/m^3 , were chosen by formulas for the water content of overall calculation method and fixed volume content of aggregate method. The fluidity, deformability, filling ability and segregation resistance were evaluated by using the V-funnel test, slump flow test, L-box test, U-box test, sieve segregation test, column segregation test and surface settlement test, results show that： SCLC60 formulated meets the working performance requirements of self-compacting concrete.
