Concrete admixture, preparation method thereof and concrete added with concrete admixture
The invention relates to a concrete admixture, and relates to the technical field of concrete. The concrete admixture is prepared from the following raw materials by weight: 40%-57% of blast furnace slag, 15%-25% of coal ash, 3%-5% of gypsum powder, 3%-5% of silica sand powder, 10%-15% of silica fume, 3%-5% of calcium powder, 8%-15% of microspheres and 1%-5% of glass powder. The concrete admixturehas the advantage that the strength, frost resistance and impermeability of the concrete are effectively enhanced. The invention also discloses a preparation method of the concrete admixture. The preparation method comprises the following steps: weighing the components according to the mass ratio, mixing the weighed components, and crushing until the specific surface area is 500-1200m <2>/g. According to the method, effective mixing and reaction of all components of the concrete admixture can be promoted, so that the prepared concrete admixture has excellent performance of improving the strength of concrete. The invention also discloses concrete added with the concrete admixture. The concrete is prepared from the following components in parts by weight: 290 to 300 parts of cement, 1100 to 1200 parts of broken stone, 680 to 880 parts of sand, 120 to 130 parts of the concrete admixture, 100 to 120 parts of water and 7 to 10 parts of a water reducer. The concrete has the advantages of relatively excellent strength, freezing resistance and impermeability.
本发明涉及一种混凝土掺料，涉及混凝土的技术领域，其由以下重量百分比的原料制成：高炉矿渣40%‑57%；煤灰15%‑25%；石膏粉3%‑5%；硅砂粉3%‑5%；硅灰10%‑15%；钙粉3%‑5%；微珠8%‑15%；玻璃粉1%‑5%，其具有有效增强混凝土的强度、抗冻性和抗渗性的优势。本发明还公开了一种混凝土掺料的制备方法：按质量配比称取各组分；将称取的各组分混合，粉碎至比表面积为500‑1200m/g；本方法能够促进混凝土掺料各组分有效混合和反应，使得制得的混凝土掺料具有较优的提高混凝土强度的性能。本发明还公开了一种加有混凝土掺料的混凝土，由以下重量份的组分制成：水泥290‑300份；碎石1100‑1200份；砂680‑880份；混凝土掺料120‑130份；水100‑120份；减水剂7‑10份，其具有较优的强度、抗冻性和抗渗性的优势。
