Hydrophobic concrete
The invention provides hydrophobic concrete, and relates to the technical field of concrete preparation. Comprising the following components: a cementing material and an additive, the cementing material comprises cement and modified fly ash in a mass ratio of (1-3): 1; the additive comprises a water repellent agent, a water reducing agent and calcium stearate; and the admixture comprises the following components in percentage by mass: 5-7% of a water repellent agent, 0.5-1% of a water reducing agent and 3-5% of calcium stearate. The hydrophobic concrete material is low in surface energy and high in hydrophobic impermeability.
本发明提供一种疏水混凝土，涉及混凝土制备技术领域。包括以下组分：胶凝材料、外加剂；胶凝材料包括质量比为(1‑3):1的水泥和改性粉煤灰；外加剂包括疏水剂、减水剂、硬脂酸钙；外加剂占胶凝材料的质量百分比为：疏水剂5％‑7％、减水剂0.5％‑1％、硬脂酸钙3％‑5％。疏水混凝土材料的表面能低、疏水抗渗能力强。
