High-performance self-leveling cement and preparation method thereof
The invention discloses high-performance self-leveling cement characterized by comprising the components in percentage by weight: 50 percent to 94 percent of a silicate cementing material and 6 percent to 50 percent of anti-crack double-fast sulphoaluminate cement. A preparation method of the self-leveling cement comprises the steps: S100, weighing a mixture of special cement clinker and gypsum, water granulated slag, fly ash and mineral powder, mixing, adding a grinding aid, and grinding to obtain the silicate cementing material; S200, weighing anti-crack double-fast sulphoaluminate cement, adding the silicate cementing material, and uniformly mixing to obtain the high-performance self-leveling cement; and S300, carrying out a performance test on the high-performance self-leveling cement.The material prepared by the method provided by the embodiment of the invention has the characteristics of small fluidity time-dependent loss, high one-day strength, controllable setting time and thelike, and solves the problems of poor fluidity, insufficient early strength, overlong setting time, drying cracking after self-leveling construction and the like in existing cement.
本发明公开了一种高性能自流平水泥，其特征在于，以重量百分比计，所述水泥包括50％‑94％的硅酸盐质胶凝材料和6％‑50％的抗裂双快硫铝酸盐水泥。该自流平水泥的制备方法包括：S100、称取专用水泥熟料和石膏的混合物、水渣、粉煤灰和矿粉并混合，并向其中加入助磨剂磨制成硅酸盐质胶凝材料；S200、称取抗裂双快硫铝酸盐水泥加入所述硅酸盐质胶凝材料并混合均匀，制得高性能自流平水泥；S300、对所述高性能自流平水泥进行性能测试。本发明实施例制备的材料具有流动度经时损失小、1天强度高和凝结时间可控等特点，解决了现有水泥存在的材料流动度差、早期强度不够、凝结时间过长和自流平施工完成后干燥开裂等问题。
