C15混凝土配合比?
1、混凝土强b度:C15,坍落度:35-50mm,砂型:中砂,配制强度21.6,石材更大粒径40mm,水泥强度32.5,每立方米用量;
2、水泥246kg/m3砂76kg/m3砾石119kg/m3水175kg/m3
以上混合比1:1:3.12:4.78: 0.71
3、砂粒体积0.33M3,砾石0.83M3
4、它取决于混凝土的强度等级,强度等级不同,数量也不同。这些数据是通过标准实验室获得的。使用中砂,细度模数为2.94,碎石为5~31.5毫米连续粒径。各等级的混凝土配合比也可通过添加外加剂来调节。
5、原标准公式与本标准所采用的公式没有实质性差异。主要引用ACI 214-77推荐的混凝土强度试验结果评定 *** (1989)。ACI214-77指出,任何设计所需的平均强度FCR可根据所使用的偏差系数(CV)或标准偏差()由公式(1)或(1a)计算。
c15混凝土配合比
c15混凝土配合比为0.58:1:2.081:3.952。混凝土分为不同的强度等级,其中混凝土标号的数字越大,代表混凝土的强度等级越高,其性能也将更好。水泥质量和混凝土的水灰比决定了混凝土的质量。
