Oil-resistant cement mortar and preparation method thereof
The invention relates to oil-resistant cement mortar, which is prepared from the following raw materials in parts by weight: 50 to 70 parts of Portland cement, 25 to 45 parts of yellow sand, 30 to 40 parts of mineral powder, 2 to 5 parts of early strength agent, 6 to 12 parts of air entraining agent, 2 to 6 parts of water reducing agent, 12 to 22 parts of coal ash and 0.5 to 1.5 parts of impermeable fiber, the anti-seepage fiber can be one of basalt fiber and polypropylene fiber. According to the oil-resistant cement mortar and the preparation method thereof, the mineral powder is doped into the cement mortar mixture, so that gaps of cement particles can be filled, the closest packing is formed, a dense structure is formed, and the oil seepage resistance and the concrete strength are improved, so that the cement mortar does not react with vegetable oil, animal oil and mineral oil; the penetration of various greases to the concrete foundation surface is effectively resisted, the influence of oils on the strength of the concrete member is avoided, the construction is simple, and only a proper proportion of clear water needs to be added for stirring.
本发明涉及一种耐油水泥砂浆，包括以下份数的原料：硅酸盐水泥50‑70份、黄沙25‑45份、矿粉30‑40份、早强剂2‑5份、引气剂6‑12份、减水剂2‑6份、粉煤灰12‑22份、防渗纤维0.5‑1.5份，所述早强剂可为硫酸钠、亚硝酸盐和硫氰酸酯(盐)其中的一种，所述防渗纤维可为玄武岩纤维和聚丙烯纤维其中的一种。该耐油水泥砂浆及其制备方法，通过在水泥砂浆混合中掺入矿粉，可以填充在水泥颗粒的空隙，构成最密堆积，形成密实结构，提高抗油渗能力和混凝土强度，使得水泥砂浆不与植物油、动物油及矿物油类起反应，有效抵抗各种油脂对混凝土基础面的渗透，避免了油类对混凝土构件强度的影响，且施工简单，只需加入适当比例清水搅拌即可。
