一种混凝土外加剂及使用其的一种预拌透水混凝土
摘要：
本发明涉及一种预拌透水混凝土外加剂及透水混凝土。所述预拌透水混凝土外加剂由以下各组分按重量百分比混合而成：减水组分10‑20%，水化调控组分1‑5%，粘度调节组分0.1‑1.0%，水分蒸发抑制组分0.5‑5%，触变剂组分0.5‑3%，余量为水。本发明所述预拌透水混凝土外加剂可有效改善透水混凝土的工作状态，极大地提高骨料表面浆体包裹的粘聚性、均匀性，并且可有效延长透水混凝土可工作时间，满足透水混凝土预拌生产、长距离运输和长时间施工的要求，促进透水混凝土生产、施工质量的控制。
摘要（英）：

The invention relates to a pre-mixed and water-permeable concrete admixture and water-permeable concrete. The pre-mixed and water-permeable concrete admixture is formed by mixing of the following components in percentage by weight: 10-20% of a water reducing component, 1-5% of a hydration regulating and controlling component, 0.1-1.0% of a viscosity regulating component, 0.5-5% of a water evaporation inhibiting component, 0.5-3% of a thixotropic agent component, and the balance of water. The pre-mixed and water-permeable concrete admixture provided in the invention can effectively improve work conditions of the water-permeable concrete, greatly improve the cohesiveness and the uniformity of slurry wrapping aggregate surfaces, and can effectively prolong the operable time of the water-permeable concrete, meet the requirements of pre-mixing production, long-distance transportation and long-time construction of the water-permeable concrete, and improve the control of production and construction quality of the water-permeable concrete.
