Concrete admixture and preparation method thereof
The invention relates to a concrete admixture and a preparation method thereof. The concrete admixture is prepared from the following raw materials in parts by weight: 35-55 parts of fly ash, 10-25 parts of silica fume, 15-30 parts of granulated blast furnace slag, 5-10 parts of volcanic ash, 2-8 parts of a grinding aid, 1-3 parts of a dispersant, 2-5 parts of a modifier and 70-120 parts of water. According to the concrete admixture and the preparation method thereof, the concrete admixture is made into liquid, in the using process, the liquid can be directly pumped into concrete stirring equipment through a water pump, manual feeding is not needed, the proportion of the liquid can be controlled according to the water flow, and the liquid and water are fed into a stirring machine together during concrete production; the water consumption can be reduced, and the fly ash particles and cement hydration products gradually form firm connection, so that the strength, watertightness and wear resistance of the concrete are improved, the binding power of an aggregate interface is improved, the physical and mechanical properties of the concrete are greatly improved, and the compressive strength, the tensile strength, the bending strength and the shear strength of the concrete are improved. The concrete hydration heat is obviously reduced.
本发明涉及一种混凝土掺合料及其制备方法，包括以下重量份的原料制成：粉煤灰35‑55份、硅灰10‑25份、粒化高炉矿渣15‑30份、火山灰5‑10份、助磨剂2‑8份、分散剂1‑3份、改良剂2‑5份和水70‑120份。该混凝土掺合料及其制备方法，将混凝土掺合料制作成液体，在使用的过程中，通过水泵可直接将液体抽入混凝土搅拌设备的内部，无需人工上料，而且其比例可根据水流量进行控制，在混凝土生产的时候同水一起送入搅拌机内，可降低用水量，粉煤灰颗粒和水泥水化产物之间逐步形成牢固联系，从而导致混凝土强度、不透水性和耐磨性的增长，提高了集料界面粘结力，使混凝土的物理力学性能大大提高，增加混凝土抗压、抗拉、抗弯、抗剪强度。显著降低混凝土水化热。
