The invention discloses energy-saving anti-crack concrete, which is prepared from the following raw materials in parts by weight: 16 to 25 parts of boiler waste residue, 22 to 34 parts of desulfurized fly ash, 30 to 38 parts of fly ash, 7 to 11 parts of cement, 14 to 21 parts of lime, 1 to 3 parts of gypsum, 5 to 8 parts of coarse and fine aggregates, 3 to 6 parts of a fine grinding admixture and 1.2 to 1.6 parts of a retarder, different industrial fixed waste materials are added into concrete, different anti-crack fibers are added into the concrete in the corresponding different industrial fixed waste materials, the formed concrete block is subjected to an anti-crack pressure test experiment under the condition of raw material proportioning, and the surface crack area of the concrete block is observed, and the concrete with the best anti-cracking effect under the corresponding raw material ratio can be screened out according to the sizes of the surface crack areas of different concrete blocks, so that the method can be suitable for construction site operation needing higher anti-cracking strength.
本发明公开了一种节能抗裂混凝土，所述节能抗裂混凝土材料包括以下重量份数：所述混凝土砌块的原料包括如下重量份数的各组分：锅炉废渣16～25份、脱硫灰22～34份、粉煤灰30～38份、水泥7～11份、石灰14～21份、石膏1～3份、粗、细骨料5～8份、细磨掺合料3～6份、缓凝剂1.2～1.6份，本发明通过采用向混凝土内加入不同工业固定废料，并在相应不同工业固定废料内的混凝土内加入不同抗裂纤维，通过在此种原料配比情况下对成型的混凝土砌块进行抗裂压力测试实验，通过观察混凝土砌块表面裂纹面积，通过不同混凝土砌块表面裂纹面积大小，能够筛选出相应原料配比下抗裂效果最佳的混凝土，从而能够适用于需要抗裂强度更大的施工现场作业。
