Concrete composite admixture and preparation method thereof
The invention discloses a concrete composite admixture, which is prepared from the following raw materials in parts by mass: 50-60 parts of silica powder, 15-30 parts of fly ash, 15-30 parts of limestone powder, 10-20 parts of steel slag powder, 8-20 parts of tuff powder and 5-15 parts of an activating agent. According to the technical scheme, an activating agent is prepared first and then added into a stirrer for stirring with other crushed raw materials, concrete can be fully and uniformly stirred, and by adding the activating agent, the composite admixture has relatively high activity, thecompressive strength of the concrete is further improved after 28 days, various properties of the concrete are greatly improved, and the properties of the mineral admixture are fully excited.
本发明公开了一种混凝土复合掺合料，包括以下质量份的原料：硅微粉50‑60份，粉煤灰15‑30份，石灰石粉15‑30份，钢渣粉10‑20份，凝灰岩粉8‑20份，活化剂5‑15份；本发明的技术方案是先制备活化剂后再与其他的粉碎后的原料一起加入搅拌机中搅拌，能使得混凝土充分的搅拌均匀，通过活化剂的加入，本发明的复合掺合料具备较高的活性且在28天后混凝土的抗压强度进一步提高，大大的提高了混凝土的各项性能，使矿物掺合料的性能得到充分激发。
