The invention relates to the technical field of concrete, and particularly discloses anti-cracking concrete and a preparation method thereof. The anti-cracking concrete is prepared from the following raw materials in parts by weight: 30 to 40 parts of cement, 10 to 15 parts of fly ash, 50 to 70 parts of recycled fine aggregate, 60 to 80 parts of recycled coarse aggregate, 1 to 5 parts of water reducing agent, 8 to 25 parts of hybrid fiber, 5 to 12 parts of ferronickel slag sand, 12 to 28 parts of composite material and 15 to 25 parts of water, wherein the composite material is a compound of kenaf fiber and superfine calcium carbonate; the preparation method comprises the following steps: uniformly mixing the cement, the fly ash, the recycled fine aggregate, the recycled coarse aggregate, the water reducing agent, the hybrid fiber, the ferronickel slag sand, the composite material and the water to obtain the anti-cracking concrete. The anti-cracking concrete disclosed by the invention has the advantage of improving the cracking resistance of the concrete through the synergistic effect of the raw materials.
本申请涉及混凝土的技术领域，具体公开了一种抗开裂的混凝土及其制备方法。抗开裂的混凝土包括以下重量份的原料：水泥30‑40份、粉煤灰10‑15份、再生细骨料50‑70份、再生粗骨料60‑80份、减水剂1‑5份、混杂纤维8‑25份、镍铁渣砂5‑12份、复合材料12‑28份、水15‑25份；其中，复合材料为红麻纤维和超细碳酸钙的复合物；其制备方法为：将水泥、粉煤灰、再生细骨料、再生粗骨料、减水剂、混杂纤维、镍铁渣砂、复合材料、水混合均匀，得到抗开裂的混凝土。本申请的抗开裂的混凝土，通过各原料之间的协同作用，具有提高混凝土抗开裂的优点。
