c混凝土配合比表

1、混凝土需要用水泥作胶凝材料，砂、石作集料，与水按一定比例配合，经搅拌、成型、养护才能形成，而混凝土按标准抗压强度划分的强度等级，称为标号，分为C10、C15、C20、C25等，C25混凝土配合比是多少呢？更多与混凝土、装修相关的资讯，请点击浏览一、c25混凝土配合比1、C25混凝土配合比水泥？：水：砂：？碎石372:175?:593?:?1260?1?:0.47:1.59:?3.392、调整水灰比调整水灰比为0.42，用水量为175kg，水泥用量为Mco=175/0.42=417kg,按重量法计算砂、石用量分别为：Mso=579kg,Mgo=1229kg3、混凝土配合比的试配、调整与确定试用配

2、合比1和2,分别进行试拌：配合比1:水泥：水：砂：碎石=372:175:593:1260=1:0.47:1.59:3.39;试拌材料用量为：水泥：水：砂：碎石=8.5:4.0:13.52:28.82kg;拌和后，坍落度为30mm,达到设计要求；配合比2:?水泥：水：砂：碎石=417:175:579:1229=1:0.42:1.39:2.95试拌材料用量为：水泥：水：砂：碎石=9.6:4.03:13.34:28.42kg,增加拌和用水<:砂：拌和后，坍落度仅20mm,达不到设计要求，故保持水灰比不变，增加水泥用量500g210g，再拌和后，坍落度达到35mm,符合设计要求。此时，实际各材料
