Anti-freezing concrete composition and preparation method thereof
The invention provides an anti-freezing concrete composition and a preparation method thereof, and the anti-freezing concrete composition is composed of the following raw materials by weight: 150-175kg/m < 3 > of water, 310-330 kg/m < 3 > of cement, 30-40 kg/m < 3 > of mineral powder, 25-35 kg/m < 3 > of fly ash, 700-745 kg/m < 3 > of sand, 1000-1100 kg/m < 3 > of stone, 9-12 kg/m < 3 > of an admixture and 28-39 kg/m < 3 > of an expension agent. According to the invention, proper aggregate and excellent proportion are adopted, and a reasonable construction process is matched, so that the product has the advantages of high strength, freezing resistance and seepage resistance after being poured, large-volume concrete such as ship locks, dams and the like can be prevented from generating cracks, the durability and the bearing capacity of concrete components are improved, and the service life is prolonged.
本发明提供一种抗冻混凝土组合物及其制备方法，一种抗冻混凝土组合物，由以下重量份数原料组成：水150‑175kg/m3、水泥310‑330kg/m3、矿粉30‑40kg/m3、粉煤灰25‑35kg/m3、砂子700‑745kg/m3、石子1000‑1100kg/m3、外加剂9‑12kg/m3、膨胀剂28‑39kg/m3。本发明采用合适的骨料和优良的配比，配合合理的施工工艺，使得混凝土在浇筑后，具备高强度、抗冻和抗渗的优点，能够防止船闸和大坝等大体积混凝土产生裂缝，有利于提高混凝土构件的耐久性和承载力，从而提高使用寿命。
