Impermeable concrete admixture
The invention relates to the technical field of building materials, and provides an anti-seepage concrete admixture which is prepared from the following raw materials in parts by weight: 40-50 parts of limestone powder, 30-40 parts of sodium silicate, 20-30 parts of hexadecyl trimethoxy silane, 10-20 parts of silicon dioxide and 5-10 parts of a water blocking agent, and the water blocking agent is prepared by mixing benzoic anhydride and barium oxide. By means of the technical scheme, the problem that in the prior art, an anti-seepage concrete admixture does not obviously improve the anti-seepage capacity of concrete is solved.
本发明涉及建筑材料技术领域，提出了一种抗渗混凝土外加剂，原料包括以下重量份的组分：石灰石粉40‑50份、硅酸钠30‑40份、十六烷基三甲氧基硅烷20‑30份、二氧化硅10‑20份、阻水剂5‑10份，阻水剂由苯甲酸酐和氧化钡混合而成。通过上述技术方案，解决了现有技术中的抗渗混凝土外加剂对混凝土抗渗能力提升不明显的问题。
