The invention provides impermeable concrete. The impermeable concrete is prepared from the following construction raw materials in parts by weight: 100 parts of cement, 330 parts of coarse aggregate, 250 parts of fine aggregate, 65 parts of fly ash, 30 parts of an additive and 55 parts of water, the admixture comprises 6 parts of an air entraining agent, 6 parts of impermeable fibers, 6 parts of an expanding agent, 6 parts of a water reducing agent and 6 parts of a waterproof agent. The total alkali amount of the impervious concrete is 1t; the raw materials are simple, and the construction is convenient. The air entraining agent changes the internal pore structure of the concrete and cuts off a capillary channel; and the anti-seepage fibers have a crack resisting effect on cracks, so that the brittleness of the concrete is reduced. The anti-seepage concrete provided by the invention is used for construction of a roof structure, after stirring, pouring, vibrating and curing are completed, the anti-seepage strength of the anti-seepage concrete is far higher than that of common concrete, and after 14-day testing, the anti-seepage concrete is free of water seepage and water leakage, higher in weather resistance and not prone to cracking.
本发明提供了一种抗渗混凝土,其施工原料包含如下重量份的成分:水泥100份、粗骨料330份、细骨料250份、粉煤灰65份、外加剂30份、水55份;所述外加剂中包括引气剂6份、防渗纤维6份、膨胀剂6份、减水剂6份、防水剂6份。该抗渗混凝土总碱量<2.25kg/m3,原料简单施工方便。本发明引气剂使混凝土内部孔隙结构改变,截断毛细管通道;防渗纤维对裂缝具有阻裂作用,降低了混凝土的脆性。将本发明提供的抗渗混凝土用于屋顶结构的建设,经搅拌、浇筑、振捣、养护完毕后,抗渗混凝土的抗渗强度远大于普通混凝土抗渗强度,进行14天的测试不渗水不漏水,耐候性更强不易开裂。
