Concrete exposed aggregate and preparation method thereof
The invention discloses a concrete exposed aggregate and a preparation method thereof, and belongs to the technical field of constructional engineering. The product adopts multi-element retarding components such as hydroxycarboxylic acid or salt thereof, aminocarboxylic acid or salt thereof, a hydration retarder, an inorganic salt retarder and the like, the retarding effect is more excellent, the effective time can be prolonged to 72 hours, meanwhile, the product can adapt to various cement varieties, and the production requirement is met. The product has the advantages of no toxicity, no harm, no corrosion to reinforcing steel bars, strong adhesion capability, capability of uniformly adhering to a template, no dripping and hanging, strong infiltration capability, capability of infiltrating into concrete by 3-5mm according to requirements, and capability of meeting design requirements. The long-term strength of the component is not influenced. The exposed aggregate can efficiently solve the problems of adaptability, long-time acting effect and complex process of the concrete exposed aggregate. The product is simple in production process, low in equipment requirement, safe and rapid.
本发明公开了一种混凝土露骨剂及其制备方法，属于建筑工程技术领域。该产品采用羟基羧酸或其盐、氨基羧酸或其盐、水化缓凝剂、无机盐缓凝剂等多元缓凝组分，缓凝效果更优秀，且能将有效时间提升到72小时，同时能适应各种水泥品种，满足生产要求。该产品无毒无害，对钢筋没有腐蚀，附着能力强，能均匀的附着于模板上，不滴挂，渗透能力强，能根据要求渗透混凝土3‑5mm，满足设计要求。对构件后期强度无影响。该露骨剂能够高效的解决混凝土露骨剂适应性问题、长时间作用效果的问题和工艺复杂的问题。该产品生产工艺简单，对设备要求低，安全快速。
