CMA concrete with masonry structure strength grade of C20 and preparation method of CMA concrete
The invention discloses CMA concrete with a masonry structure strength grade of C20 and a preparation method of the CMA concrete. The concrete is composed of CMA, cement, fly ash, coarse sand, fine sand, broken stone, water and a water reducing agent, and the mixing ratio of the CMA to the cement to the fly ash to the coarse sand to the fine sand to the broken stone to the water to the water reducing agent is 9.5:180.5:110:444:445:1010:165:5.3 according to the unit of kg/m<3>. The preparation method comprises the steps: pouring the cement, the fly ash, the coarse sand, the fine sand and the broken stone which are weighed according to the proportion into a stirrer to be stirred, then adding the water in which the solid water reducing agent is melted into the stirred materials in the stirrerto be stirred together, and discharging to obtain the prepared concrete mixture. The concrete mixture is prepared into a test block, the test block is subjected to a mechanical test, and the 28-day compressive strength value of the test block is 20.15 MPa. The CMA concrete has the advantages of ecological environmental protection, low production cost, thermal insulation and high firmness, and hasgreat application value.
一种用于砌体结构强度等级为C20的CMA混凝土及其制备方法，混凝土由CMA、水泥、粉煤灰、粗砂、细砂、碎石、水及减水剂组成，其配合比为(单位：kg/m)：CMA：水泥：粉煤灰：粗砂：细砂：碎石：水：减水剂为：9.5：180.5：110：444：445：1010：165：5.3；将按以上配比称量好的水泥、粉煤灰、粗砂、细砂、碎石倒入搅拌机中搅拌，再将融化了固体减水剂的水加入到搅拌机中搅好的材料中一起搅拌，出料即得所制备混凝土拌合物；将混凝土拌合物制成试块，对试块进行力学试验，试块的28天抗压强度值为20.15MPa；本发明具有生态环保、生产成本低及保温隔热及坚固性高的优点，具有很大的应用价值。
