    • A composition that may be used to retain moisture within fresh concrete as it cures to optimize the curing of the concrete may include one or more hardening and densifying agents and one or more temporary moisture sealing agents. Additionally such a composition may include a siliconate. The hardening and densifying agent of such a composition may penetrate the surface of fresh concrete to react with free lime, providing the fresh concrete with a strong surface. The temporary moisture sealing agent may form a moisture barrier on the surface of the fresh concrete to prevent moisture from escaping from the fresh concrete before the fresh concrete has sufficiently cured. The temporary moisture sealing agent may degrade within a matter of days, facilitating its removal from the surface of the concrete once the concrete has cured and enabling further treatment of the surface without undue delay.
    • 可以用于在新鲜混凝土中保持水分的组合物,因为其固化以优化混凝土的固化可包括一种或多种硬化和致密剂和一种或多种临时水分密封剂。 另外,这种组合物可以包括硅酸盐。 这种组合物的硬化和致密剂可以穿透新鲜混凝土的表面以与游离石灰反应,为新鲜混凝土提供强烈的表面。 临时防潮剂可在新拌混凝土表面形成防潮层,防止新拌混凝土充分固化之前,水分从新拌混凝土中逸出。 临时防潮剂可能在几天内降解,一旦混凝土固化,便于其从混凝土表面去除,并能进一步处理表面而不会有不适当的延迟。
