C30-strength-grade CMA concrete for masonry structure and preparation method of CMA concrete
The invention discloses C30-strength-grade CMA concrete for a masonry structure and a preparation method of the C30-strength-grade CMA concrete. The concrete is composed of CMA, cement, fly ash, coarse sand, fine sand, gravels, 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 gravels to the water to the waterreducing agent of 13.5: 256.5: 90: 427: 427: 1004: 165: 6.3; the cement, the fly ash, the coarse sand, the fine sand and the gravels which are weighed according to the above ratio are poured into a stirrer to be stirred, then the water in which the solid water reducing agent is melted is added into the stirred materials in the stirrer to be stirred together with the materials, and an obtained mixture is discharged, so that the prepared concrete mixture can be obtained. 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 30.14 MPa. The CMA concrete has the advantages of ecologically environmental friendliness, low production cost, thermal insulation and high firmness, and has great application value.
一种用于砌体结构强度等级为C30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：13.5：256.5：90：427：427：1004：165：6.3；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30.14MPa；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。
