High-strength impermeable concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses high-strength impermeable concrete and a preparation method thereof. The high-strength impermeable concrete comprises the following components in parts by weight: 200-300 parts of sulphoaluminate cement; 5-10 parts of an impermeable waterproof agent; 900-1000 parts of fine stone; 700-800 parts of sand; 5-10 partsof a water reducing agent; 200-250 parts of water; 5-7 parts of an air entraining agent; and 100-200 parts of fly ash; and the impermeable waterproof agent comprises the following components: EVA redispersible latex powder, water, sodium methylsilanolate, hydrochloric acid, silicon dioxide and calcium oxide. The preparation method comprises the following steps: mixing the sulphoaluminate cement, the sand, the fine stone and the fly ash to obtain a mixture A; adding the water reducing agent,the impermeable waterproof agent and the air entraining agent into water, and mixing to obtain a mixtureB; and adding the mixture B into the mixture A, and stirring and mixing. The high-strength impermeable concrete prepared by the invention has the advantages of better impermeability, high strength andthe like.
本申请涉及混凝土技术领域，具体公开了一种高强抗渗混凝土及其制备方法。高强抗渗混凝土包括如下重量份数的组分：硫铝酸盐水泥200‑300份；抗渗防水剂5‑10份；细石900‑1000份；砂子700‑800份；减水剂5‑10份；水200‑250份；引气剂5‑7份；粉煤灰100‑200份；抗渗防水剂包括如下组分，EVA可再分散乳胶粉、水、甲基硅醇钠、盐酸、二氧化硅、氧化钙。其制备方法为：将硫铝酸盐水泥、砂子、细石、粉煤灰混合得到混合物A；将减水剂、抗渗防水剂、引气剂加入水中混合得到混合物B；将混合物B加入混合物A中搅拌混合。本申请制成的高强抗渗混凝土，具有较好的抗渗能力，同时还具备高强度等优点。
