The invention belongs to the technical field of building materials, and discloses a concrete formula. The concrete formula comprises the following components by weight: 129.5-140 parts of cement, 125.5 to 130 parts of an ultrafine mineral admixture, 80 parts of fly ash, 300 parts of yellow sand, 578 to 585.5 parts of washed sand, 1010 to 1017.5 parts of broken stone, 7 parts of a water reducing agent and 120-130 parts of water. According to the concrete formula, under the condition that the strength of concrete is guaranteed, the use requirement of the cement is greatly reduced, and the production cost of the concrete is saved; and the use amount of cement is reduced, so the influence of hydration heat on the concrete can be effectively reduced, and the crack resistance of the concrete isimproved.
本发明属于建筑材料技术领域，公开了一种混凝土配方，按重量份包括以下组分：水泥129.5～140份；超细矿物掺合料125.5～130份；粉煤灰80份；黄沙300份；水洗砂578～585.5份；碎石1010～1017.5份；减水剂7份；水120～130份。该混凝土配方在保证混凝土强度的情况下，大大降低了水泥的使用需求，节约了混凝土的生产成本；而水泥的使用量减少，能够有效地减少水化热对混凝土的影响，提升混凝土的抗裂性能。
