ADDITIVES FOR GEOPOLYMER CEMENTS
The present disclosure is directed to chemical additives for geopolymer cements that can improve the rheological properties of geopolymer cements. These chemical additives include sulfates and selenates of a specific formula as well as hydroxycarboxylic acid salts of Li, Na, and K including but not limited to glycolic, lactic, citric, mandelic tartaric, and malic acids. The chemical additives for geopolymer cements disclosed herein can facilitate the uniform mixing, increase the time mixtures can be transported, and improve the ability to place and finish concrete and mortars made with the geopolymer cements.
本公开针对用于无机聚合物水泥的化学添加剂，其可以改善无机聚合物水泥的流变性质。这些化学添加剂包括特定式的硫酸盐和硒酸盐以及Li、Na和K的羟基羧酸盐，包括但不限于乙醇酸、乳酸、柠檬酸、扁桃酸酒石酸和苹果酸的。本文公开的用于无机聚合物水泥的化学添加剂可以促进均匀混合，增加混合物可被运输的时间，并且改善放置和后处理由该无机聚合物水泥制成的混凝土和砂浆的能力。
