High-strength and anti-crack concrete prefabricated part and preparation method thereof
The invention relates to the field of concrete prefabricated parts, and particularly discloses a high-strength and anti-crack concrete prefabricated part and a preparation method thereof. The high-strength and anti-crack concrete prefabricated part comprises the following components in parts by weight: 0.3-0.6 part of reinforced fibers; 1-3 parts of a kiwi fruit vine extract; 25 to 42 parts of a cementing material; 98 to 123 parts of coarse aggregate; 52 to 78 parts of fine aggregate; 11 to 16 parts of water; 3.2 to 5.6 parts of water glass; 0.5 to 0.9 part of sodium fluosilicate; 1-2 parts of an additive; the reinforced fibers are obtained by grafting modification by taking methyl methacrylate as a monomer; the kiwi fruit vine extract is obtained by taking kiwi fruit vines as raw materials through crushing, water extraction and ethanol extraction. The kiwi fruit vine extract is added into the components of the high-strength and anti-cracking concrete prefabricated part, so that the strength and the anti-cracking performance of the prefabricated part are improved.
本申请涉及混凝土预制件的领域，具体公开了一种高强、抗裂混凝土预制件及其制备方法。一种高强、抗裂混凝土预制件包括如下重量份数的组分：增强纤维0.3‑0.6份；猕猴桃藤提取物1‑3份；胶凝材料25‑42份；粗骨料98‑123份；细集料52‑78份；水11‑16份；水玻璃3.2‑5.6份；氟硅酸钠0.5‑0.9份；外加剂1‑2份；所述增强纤维以甲基丙烯酸甲酯为单体接枝改性得到；所述猕猴桃藤提取物以猕猴桃藤为原料，经粉碎、水提取、乙醇萃取得到。本申请的一种高强、抗裂混凝土预制件的组分中添加有猕猴桃藤提取物，提高预制件的强度和抗裂性能。
