Solidification control composition for gelling systems
A set control composition for a gelling system comprising: a) (a-1) a hydroxymonocarboxylic acid or a salt thereof, and (a-2) optionally a polycarboxylic acid or a salt thereof having an equivalent weight of carboxylic acid of 333 or less, the equivalent weight of carboxylic acid being the molecular weight of the polycarboxylic acid divided by the number of carboxylic acid functional groups wherein the carboxyl groups of (a-1) comprise at least 90% of the total number of carboxyl groups of (a-1) and (a-2), and the equivalent weight of carboxylic acid is at least 90% of the total number of carboxyl groups of (a-1) and (a-2). B) at least one of (b-1) a borate source and (b-2) a carbonate source wherein the carbonate source is selected from the group consisting of inorganic carbonates having a water solubility of 0.1 g.L <-1 > or more at 25 DEG C and organic carbonates, the weight ratio of b) to a) is in the range of 1.2 to 20, and c) a polyol, the weight ratio of c) to a) is in the range of 1.0 to 10. The solidification control composition for the gelling system effectively improves the processability of the gelling system over a long period of time without compromising the early compressive strength.
用于胶凝体系的凝固控制组合物包含：a)(a‑1)羟基单羧酸或其盐，和(a‑2)任选地，羧酸当量重量为333或更小的多羧酸或其盐，羧酸当量重量是多羧酸的分子量除以羧酸官能团的数量，其中(a‑1)的羧基占(a‑1)和(a‑2)的羧基总数的至少90％，b)(b‑1)硼酸盐源和(b‑2)碳酸盐源中的至少一种，其中碳酸盐源选自在25℃下水溶解度为0.1g·L‑1或更高的无机碳酸盐，以及有机碳酸酯，b)与a)的重量比为1.2至20，以及c)多元醇，c)与a)的重量比为1.0至10。所述用于胶凝体系的凝固控制组合物在长时间内有效改善胶凝体系的可加工性而不损害早期抗压强度。
