Heat slow-release repair material and heat slow-release capsule suitable for emergency repair project in cold region and preparation method of heat slow-release repair material and heat slow-release capsule
The invention discloses a heat slow-release repair material and a heat slow-release capsule suitable for first-aid repair engineering in a cold region and a preparation method of the heat slow-release repair material and the heat slow-release capsule. The heat slow-release repair material suitable for the first-aid repair engineering in the cold region comprises the following raw materials in parts by weight: 40-70 parts of Portland cement, 22.5-45 parts of sulphoaluminate cement, 7.5-15 parts of gypsum and 1-5 parts of the heat slow-release capsule. The high-performance concrete is prepared from the following components in parts by weight: 97 to 103 parts of quartz sand, 25.5 to 26.5 parts of water and 0.25 to 0.35 part of high-efficiency water According to the invention, the heat sustained-release capsule with controllable heat release amount and heat release rate is doped, and an artificially controllable heat source is formed in the matrix of the repair material, so that the problems of slow strength development, even freezing injury and the like of the cement-based repair material under the influence of low temperature in cold climate are solved; and meanwhile, dependence of emergency repair engineering in the cold region on an external heat source is reduced, and generated high energy consumption and high carbon emission are reduced.
本发明公开了一种适用于寒区抢修工程的热缓释修复材料、热缓释胶囊及其制备方法，本发明适用于寒区抢修工程的热缓释修复材料包括以下重量份数配比的原料：硅酸盐水泥40‑70份，硫铝酸盐水泥22.5‑45份，石膏7.5‑15份，热缓释胶囊1‑5份，石英砂97‑103份，水25.5‑26.5份，高效减水剂0.25‑0.35份。本发明掺入放热量、放热速率大小可控的热缓释胶囊，在修复材料基体内部形成人为可调控的热源，解决了寒冷气候下，水泥基修复材料受低温影响而强度发展缓慢甚至产生冻害等问题，同时有利于减少寒区抢修工程依赖外部热源、降低因此产生的高能耗及高碳排放。
