The invention discloses a cement admixture in the technical field of cement admixture preparation, and the cement admixture comprises an ethylenediamine tetraacetic acid solution and a polyamide solution, and the polyamide solution is in a solution state in which amino groups of polyamide are combined with carbonate radicals and bicarbonate radicals. During preparation, an ethylenediamine tetraacetic acid solution and a polyamide solution are mixed to obtain the cement admixture. According to the admixture, the carbonization speed of cement can be remarkably increased, and the compressive strength of the carbonized cement can be improved.
本方案公开了水泥外加剂制备技术领域的一种水泥外加剂，包括乙二胺四乙酸溶和聚酰胺溶液，聚酰胺溶液为聚酰胺的氨基结合碳酸根和碳酸氢根的溶液状态。制备时，将乙二胺四乙酸溶液与聚酰胺溶液混合，得到水泥外加剂。本申请的外加剂可以显著提高水泥的碳化速度并提高水泥碳化后的抗压强度。
