混凝土砂浆配合比及材料用量表

混凝土砂浆配合比及材料用量表1、混凝土配合比有关说明 （1）除碾压混凝土材料配合比及材料用量表外，水泥混凝土强度等级均以28d龄期用标准试验方法测得的具有95%保证率的抗压强度标准值确定，如设计龄期超过28d，按表7-1系数换算。计算结果如介于两种强度等级之间，应选用高一级的强度等级。表7-1 设计龄期（d）286090180强度等级折合系数1.000.830.770.71 （2）混凝土配合比表系卵石、粗砂混凝土，如改用碎石或中、细砂，按表7-2系数换算。 表7-2 项目水泥砂石子水卵石换为碎石1.101.101.061.10粗砂换为中砂1.070.980.981.07粗砂换为细砂1.100.960.971.10粗砂换为特细砂1.160.900.951.16注：水泥按重量计，砂、石方、水按体积计。（3）混凝土细骨料的划分标准为：细度模数3.19~3.85（或平均粒径1.2~2.5mm）为粗砂； 细度模数2.5~3.19（或平均粒径0.6~1.2mm）为中砂； 细度模数1.78~2.50（或平均粒径0.3~0.6mm）为细砂； 细度模数0.9~1.78（或平均粒径0.15~0.3mm）为特细砂。 （4）埋块石混凝土，应按配合比表的材料用量，扣除埋块石实体的数量计算。 1）埋块石混凝土材料量＝配合表列材料用量×（1~埋块石量%）

1块石实体方=1.67码方 2）因埋块石增加的人工见表7-3。 表7-3 埋块石率（%）5101520每100m3埋块石混凝土增加人工工时24.032.042.456.8注：不包括块石运输及影响浇筑的工时。（5）有抗渗抗冻要求时，按表7-4水灰比选用混凝土强度等。表7-4抗渗等级一般水灰比抗冻等级一般水灰比W40.60~0.65F50<0.58W60.55~0.60F100<0.55W80.50~0.55F150<0.52W12<0.50F200<0.50F300<0.45（6）除碾压混凝土材料配合参考表外，混凝土配合表的预算量包括场内运输及操作损耗在内。不包括搅拌后（熟料）的运输和浇筑损耗，搅拌后的运输和浇筑损耗已根据不同浇筑部位计入定额内。 （7）水泥用量按机械拌和拟定，若系人工拌和，水泥用量增加5%。（8）按照国际标准（ISO3893）的规定，且为了与其他规范相协调，将原规范混凝土及砂浆标号的名称改为混凝土或砂浆强度等级。新强度等级与原标号对照见表7-5和表7-6。
