Anti-crack and anti-impact concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses anti-crack and anti-impact concrete and a preparation method thereof. The anti-crack and anti-impact concrete is prepared by pouring a concrete mixture; the concrete mixture comprises the following components in parts by mass: 100 parts of water; 490 to 510 parts of cement; 530 to 540 parts of sand; 1030 to 1040 parts of stone; 20 to 24 parts of fiber; 42.1 to 47.9 parts of acetic anhydride; and 4.21 to 4.79 parts of lauryl sodium sulfate. The preparation method comprises the following steps: 1, uniformly mixing water, acetic anhydride and lauryl sodium sulfate to obtain a mixed solution; 2, adding other components except the cement into the mixed solution, and uniformly mixing the components to obtain a premix, 3, adding the cement into the premix, and uniformly mixing the premix to obtain a concrete mixture, and 4, injecting the concrete mixture into a mold, and maintaining and demolding the mixture to obtain the anti-crack and anti-impact concrete. The anti-crack and anti-impact concrete has the effect of improving the anti-crack and anti-impact performance of the concrete.
本发明涉及混凝土领域，具体公开了一种抗裂抗冲击混凝土及其制备方法。抗裂抗冲击混凝土，由混凝土拌和料浇筑制得，混凝土拌和料包括以下质量份数的组分：水100份；水泥490‑510份；砂530‑540份；石1030‑1040份；纤维20‑24份；乙酸酐42.1‑47.9份；十二烷基硫酸钠4.21‑4.79份。制备方法，包括以下步骤：步骤1），将水、乙酸酐、十二烷基硫酸钠混合均匀，获得混合液；步骤2），在混合液中加入除水泥外的剩余组分，混合均匀，获得预混物；步骤3），在预混物中加入水泥，混合均匀，获得混凝土拌和料；步骤4），将混凝土拌和料注入模具中，养护脱模，得抗裂抗冲击混凝土。本发明具有提高混凝土的抗裂抗冲击性能的效果。
