摘    要:用废混凝土破碎物代替粗骨料配制再生混凝土时,用普通混凝土配制强度公式计算其强度,会存在较大的误差,主要是公式中骨料系数A、B值不同.通过试验确定了再生骨料系数A、B值以及相应的强度计算公式,可为再生混凝土实际强度的计算提供参考.

关 键 词:再生混凝土  再生骨料  骨料系数  再生混凝土强度  计算公式  confirmation  concrete  formula  实际强度  试验  骨料系数  误差  存在  公式计算  配制强度  普通混凝土  粗骨料  废混凝土

Abstract:When regenerated concrete is prepared with waste broken concrete instead of coarse aggregate,there is a great error if the concrete compressive strength is counted by the compressive strength formula of common concrete.The error is mainly brought by the difference of the aggregate coefficient A and B in the formula.In this paper,the aggregate coefficient of A and B and the corresponding intensity formula of regenerated concrete are confirmed by experiment.The formula can provide reference for counting real regenerated concrete strength.
Keywords:regenerated concrete  recycled aggregate  aggregate coefficient
