Anti-crack concrete
The invention relates to the field of concrete, and particularly discloses anti-crack concrete. The anti-crack concrete comprises the following components in parts by weight: 30 to 40 parts of cement, 15 to 20 parts of water, 25 to 35 parts of fine aggregate, 40 to 50 parts of coarse aggregate, 5 to 10 parts of filler, 1 to 1.5 parts of a water reducing agent, 3 to 5 parts of an anti-crack fiber, 5 to 10 parts of reflective powder, 0.8 to 1 part of an expanding agent and 10 to 20 parts of rubber particles. The concrete has the advantages that heat absorption is reduced, specific heat capacity is reduced, overlarge temperature difference is avoided, porosity is increased, heat dissipation and water loss are improved, uniformity of bay temperature and humidity in a concrete part is improved, temperature cracks and shrinkage cracks are reduced, and the anti-cracking performance of the concrete can be improved by adding the anti-cracking fibers.
本申请涉及混凝土领域,具体公开了一种抗裂混凝土。抗裂混凝土包括以下重量份的组分:30‑40份水泥、15‑20水、25‑35份细骨料、40‑50份粗骨料、5‑10份填料、1‑1.5份减水剂、3‑5份抗裂纤维、5‑10份反光粉、0.8‑1份膨胀剂、10‑20份橡胶颗粒。其具有减少吸热,降低比热容,避免温差过大,增加孔隙率,从而提高散热和水分散失,提高混凝土件内湾温度和湿度的均匀性,从而减少温度裂缝和收缩裂缝的优点,增加抗裂纤维能够提高混凝土的抗裂性能。
