Carborundum concrete and preparation method thereof
The invention relates to the technical field of building materials, and particularly discloses carborundum concrete and a preparation method thereof. The carborundum concrete is prepared from the following raw materials in parts by weight: 30 to 35 parts of cement, 50 to 65.4 parts of machine-made sand, 90 to 115 parts of gravel, 15 to 27 parts of carborundum, 1 to 5 parts of a carborundum regulator, 0.1 to 2 parts of an additive and 14.5 to 16.5 parts of water; and the methylene blue value of the machine-made sand is 0.5%-1.0%. The carborundum concrete prepared according to the formula is high in workability and small in slump loss, the viscosity of the carborundum concrete can be obviously reduced, slurry can be better extracted, the initial setting time reaches 8 hours under the condition that final setting is not affected, the strength grade of the prepared carborundum concrete is at least C30, and the soil surface smoothness is good.
本申请涉及建筑材料技术领域，具体公开了一种金刚砂混凝土及其制备方法。金刚砂混凝土由包含以下重量份的原料制成：水泥30‑35份、机制砂50‑65.4份、碎石90‑115份、金刚砂15‑27份、金刚砂调节剂1‑5份、外加剂0.1‑2份和水14.5‑16.5份；所述机制砂的亚甲蓝值0.5%‑1.0%。采用本申请的配方制得的金刚砂混凝土的和易性好、塌落度损失小、能明显降低金刚砂混凝土粘稠度，更好的提浆，在不影响终凝的情况下初凝时间达到了8小时，且制得的金刚砂混凝土的强度等级至少为C30，土表面光整度好。
