高强自密实轻骨料混凝土配合比设计

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1950 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 proportion design of high strength self-compacting lightweight concrete

Mix proportions of SCLC60 of which densities are less than 1 950 kg/m3,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-compact...
