High-strength cementing agent suitable for marine sludge and preparation method of high-strength cementing agent
The invention relates to a high-strength cementing agent suitable for marine sludge and a preparation method thereof, the cementing agent is composed of a curing agent and an exciting agent, the curing agent comprises clinker, blast furnace slag powder, fly ash and gypsum, and based on the mass of the clinker, the addition amount of the other raw materials is as follows: 10-40% of blast furnace slag powder, 5-35% of fly ash and 4-16% of gypsum; and the adding amount of the exciting agent is 0.5-4.5% of the mass of the curing agent, the main material of the exciting agent is calcium silicate, and the content of the calcium silicate is greater than or equal to 98%. The preparation method comprises the following steps: mixing the clinker, blast furnace slag powder, fly ash and gypsum in proportion to obtain a curing agent mixture, and grinding the curing agent mixture through a ball mill to obtain curing agent powder; and adding the exciting agent into the curing agent powder, and uniformly stirring to obtain the cementing agent. The strength of the solidified sludge can be enhanced, high freezing resistance and softening resistance are achieved, the preparation method is easy and convenient to operate, and production is easy.
本发明涉及一种适用于海洋淤泥的高强度胶结剂及其制备方法，胶结剂由固化剂和激发剂组成，固化剂包括熟料、高炉矿渣粉、粉煤灰、石膏，其中，以熟料质量为基础计，其余原料的添加量按照相对于熟料质量的百分比为：高炉矿渣粉10‑40％，粉煤灰5‑35％，石膏4‑16％；激发剂的添加量为固化剂质量的0.5‑4.5％，激发剂的主要材料为硅酸钙，硅酸钙含量≥98％。制备方法为：将熟料、高炉矿渣粉、粉煤灰、石膏按比例进行混合，获得固化剂混合料，再经球磨机磨细，得到固化剂粉末；在固化剂粉末中加入激发剂搅拌均匀，得到胶结剂。本发明可增强固化淤泥强度，具有较高的抗冻性和抗软化性，制备方法操作简便，易于生产。
