Formula and preparation process of anti-crack concrete
The invention relates to the technical field of concrete preparation, in particular to an anti-crack type concrete formula and a preparation process. The anti-crack type concrete formula is prepared from cement mortar, stone, lime, gypsum, talc, an additive, an air entraining agent, polytetrafluoroethylene particles, an additive and a reinforcing agent; the concrete comprises the following components in parts by weight: 80-100 parts of cement mortar, 60-75 parts of gravel, 25-30 parts of lime, 30-45 parts of gypsum, 20-25 parts of talc, 15-20 parts of an additive, 5-10 parts of an air entraining agent, 5-8 parts of polytetrafluoroethylene particles, 10-13 parts of an additive and 8-10 parts of a reinforcing agent. In the concrete preparation process, the additive, the air entraining agent, the polytetrafluoroethylene particles, the additive and the reinforcing agent are added into the concrete, so that the high temperature resistance, acid and alkali resistance and density of the concrete can be fully improved, the performance of the concrete can be comprehensively improved, and the air entraining agent can form tiny air holes, so that the air entraining agent has good air permeability. Therefore, the frost resistance of the whole concrete is improved, the cracking probability of the concrete is reduced, the crack resistance of the concrete is improved, and the service life is prolonged.
本发明涉及混凝土制备技术领域，具体为一种抗裂型混凝土配方及制备工艺，抗裂型混凝土配方由水泥砂浆、石子、石灰、石膏、滑石、附加剂、引气剂、聚四氟乙烯颗粒、外加剂和增强剂，各组分的比重如下：水泥砂浆80‑100份、碎石子60‑75、石灰25‑30、石膏30‑45、滑石20‑25、附加剂15‑20、引气剂5‑10份、聚四氟乙烯颗粒5‑8份、外加剂10‑13和增强剂8‑10份。本发明，在制备混凝土的过程中，向其中分别添加有附加剂、引气剂、聚四氟乙烯颗粒、外加剂和增强剂，可以充分提高混凝土自身的耐高温性能、耐酸碱性和密度，使得混凝土自身性能得到全方位的提高，并且引气剂可以形成的微小气孔，以此来提高混凝土整体的抗冻性，减少混凝土开裂的概率，提高混凝土的抗裂性，延长使用寿命。
