Cement-based grouting material for semi-flexible pavement
The invention provides a cement-based grouting material for a semi-flexible pavement, belongs to the field of concrete, and particularly relates to a modified polycarboxylic acid water reducing agent, a preparation method of the modified polycarboxylic acid water reducing agent and the cement-based grouting material for the semi-flexible pavement containing the modified polycarboxylic acid water reducing agent. The invention relates to sulphoaluminate cement which comprises the following components in percentage by weight: sulphoaluminate cement, 10-15% of II-grade fly ash, 15-25% of 40-200-mesh quartz sand, 15-25% of 1.6-3 coal power plant slag, 0.5-1% of a modified polycarboxylate superplasticizer, 0.01-0.2% of a defoaming agent, 4-10% of a UEA expanding agent and the modified polycarboxylate superplasticizer prepared according to the method disclosed by the invention. The polycarboxylic acid water reducer has the advantages that the problem of delayed coagulation of a traditional polycarboxylic acid water reducer is solved, early strength is achieved, slurry is uniform and stable, and additional additives are not needed.
本申请提供一种半柔性路面用水泥基灌浆材料，属于混凝土领域，具体涉及改性聚羧酸减水剂及该改性聚羧酸减水剂的制备方法，含有改性聚羧酸减水剂半柔性路面用水泥基灌浆材料。含有按相对硫铝酸盐水泥重量百分比计的以下组分：硫铝酸盐水泥，10‑15%II级粉煤灰，15‑25%40‑200目石英砂，15‑25%细度1.6‑3煤电厂炉渣，0.5‑1%改性聚羧酸减水剂，0.01‑0.2%消泡剂，4‑10%UEA膨胀剂以及根据本发明方法制备的改性聚羧酸减水剂。其具有克服传统聚羧酸减水剂缓凝的问题，早强，浆料均匀稳定，无需额外添加剂的诸多优点。
