Anti-crack concrete and preparation method thereof
The invention relates to the technical field of concrete materials, in particular to anti-crack concrete and a preparation method thereof. The anti-crack concrete comprises the following components inparts by weight: 90-110 parts of Portland cement, 45-60 parts of water, 160-210 parts of gravels, 120-140 parts of sand, 20-30 parts of fly ash, 15-20 parts of a composite anti-crack agent, 9-12 parts of an additive and 2-5 parts of a composite water reducing agent. According to the invention, the composite anti-cracking agent is matched with the Portland cement, the fly ash, the admixture, the composite water reducing agent and other components, the compactness and the compressive strength of the anti-crack concrete can be improved, and the waterproof and shrinkage compensation effects of the concrete can be achieved, so that the prepared anti-crack concrete has excellent crack resistance, permeability resistance and compressive strength and is long in service life. The preparation method is simple and efficient, convenient to operate and control, stable in product quality and beneficial to industrial production.
本发明涉及混凝土材料技术领域,具体涉及一种抗裂混凝土及其制备方法。所述抗裂混凝土包括以下重量份的组分:硅酸盐水泥90‑110份、水45‑60份、碎石160‑210份、砂120‑140份、粉煤灰20‑30份、复合抗裂剂15‑20份、外加剂9‑12份、复合减水剂2‑5份。本发明通过将复合抗裂剂与硅酸盐水泥、粉煤灰、外加剂、复合减水剂以及其他组分相配合,有助于提高抗裂混凝土的密实度及抗压强度,并可起到混凝土防水和收缩补偿的作用,使制得的抗裂混凝土具有优良的抗裂性、抗渗性和抗压强度,使用年限长,其制备方法简单高效,操作控制方便,产品质量稳定,利利于工业化生产。
