Anti-crack waterproof concrete admixture and preparation method thereof
The invention relates to the technical field of concrete processing, in particular to an anti-crack waterproof concrete admixture and a preparation method thereof, and the concrete admixture comprises the following components in parts by weight: 40-60 parts of a composite solid water reducer, 30-50 parts of a retarder, 5-10 parts of an anti-freezing agent, 2-7 parts of an air entraining agent and 5-10 parts of a stabilizer. In the invention, the prepared modified water reducing agent is loaded in the composite diatomite in a vacuum impregnation manner to obtain the composite solid water reducing agent, so that the defects that the existing water reducing agent is difficult to store and high in packaging and transportation cost can be effectively overcome, the performance of the concrete can be better improved, and the concrete has good durability.
本发明涉及混凝土加工技术领域，具体涉及一种抗裂防水混凝土外加剂及其制备方法，所述混凝土外加剂包括如下重量份组分：复合型固体减水剂40‑60份、缓凝剂30‑50份、防冻剂5‑10份、引气剂2‑7份、稳定剂5‑10份。本发明中，通过真空浸渍的方式，将配置的改性减水剂负载于复合型硅藻土中，得到复合型固体减水剂，从而可以有效解决现有减水剂存在不易存储以及包装、运输成本高的缺陷，从而可以更好的提高混凝土的性能，使其具有很好的耐久性。
