Preparation method of high-strength impermeable concrete and impermeable concrete
The invention discloses a preparation method of high-strength impermeable concrete and the impermeable concrete. The impermeable concrete is prepared from the following raw materials in parts by weight: 30-50 parts of cement, 20-40 parts of water, 15-30 parts of fine sand, 30-50 parts of steel fibers, 0.3-0.6 part of silicon dioxide particles, 10-16 parts of superfine slag, 5-8 parts of an expanding agent, 3-6 parts of an active agent, 2-6 parts of a water reducing agent, 3-6 parts of sodium alkyl benzene sulfonate, 1.1-1.6 parts of hydrophilic colloid and 10-25 parts of an emulsifier. The preparation method is simple, the prepared concrete is efficient and durable in impermeability and waterproofness, internal pores of the concrete can be filled, the compactness of the concrete is improved, steel bars in a concrete structure cannot be rusted, and the anti-aging performance is good.
本发明公开了一种高强度抗渗混凝土的制备方法及抗渗混凝土，由以下原料制备而成：所述原料按重量比包括：水泥30‑50份、水20‑40份、细沙15‑30份、钢纤维30‑50份、二氧化硅颗粒0.3‑0.6份、超细矿渣10‑16份、膨胀剂5‑8份、活性剂3‑6份，减水剂2‑6份、烷基苯磺酸钠3‑6份、亲水胶体1.1‑1.6份与乳化剂10‑25份，本发明制备方法简单，所制成的混凝土抗渗防水性能高效、持久，能够对混凝土内部孔隙进行填充，提高混凝土密实度且不会对混凝土结构内部的钢筋产生锈蚀，抗老化性能佳。
