Anti-crack concrete prefabricated part and preparation method thereof
The invention relates to the technical field of concrete prefabricated parts, and particularly discloses an anti-crack concrete prefabricated part and a preparation method thereof. The anti-crack concrete prefabricated part is mainly prepared from the following raw materials in parts by weight: 150 to 160 parts of water, 240 to 270 parts of cement, 95 to 115 parts of fly ash, 60 to 70 parts of slag powder, 730 to 780 parts of sand, 980 to 1100 parts of gravel, 3 to 5 parts of phase change material, 5 to 10 parts of modified pre-oxidized fiber and 6 to 7 parts of water reducing agent. The modified pre-oxidized fiber is obtained by treating the pre-oxidized fiber with gamma-aminopropyltriethoxysilane, trimethylolpropane triacrylate, tetraethylene diamine and sodium hydroxide. According to the anti-crack concrete prefabricated part, the total cracking area is greatly reduced, the situation that the anti-crack concrete prefabricated part is damaged in the transportation and hoisting links is reduced, and the anti-crack concrete prefabricated part further has the advantages of being high in compressive strength and breaking strength and has excellent comprehensive performance.
本申请涉及混凝土预制件技术领域，具体公开了一种抗裂混凝土预制件及其制备方法。抗裂混凝土预制件主要由以下重量份的原料制成：水150‑160份、水泥240‑270份、粉煤灰95‑115份、矿渣粉60‑70份、砂子730‑780份、碎石980‑1100份、相变材料3‑5份、改性预氧丝纤维5‑10份、减水剂6‑7份；所述改性预氧丝纤维为γ‑氨丙基三乙氧硅烷、三丙烯酸三羟甲基丙烷酯、三缩四乙二胺、氢氧化钠对预氧丝纤维处理获得。该抗裂混凝土预制件，大大降低总开裂面积，降低运输和吊装环节抗裂混凝土预制件出现损坏的情况，而且还具有抗压强度高、抗折强度高的优点，具有优良的综合性能。
