Waterproof interface mortar for steel structure interior wall
The invention relates to waterproof interface mortar for a steel structure interior wall, and belongs to the technical field of building materials. The waterproof interface mortar comprises the following components in parts by weight: 100-800 parts of cement, 200-600 parts of fine quartz sand, 20-150 parts of a dispersed emulsion, 0.5-5 parts of an expanding agent, 5-50 parts of a waterproof agent, 5-15 parts of a synergistic water repellent, 2-10 parts of a water reducing agent and 0.5-5 parts of calcium formate, through the interaction of the expanding agent and the rapid hardening aluminum sulfate cement, the solidification shrinkage of the mortar is compensated, the mortar layer is compact, the waterproof agent and the synergistic water repellent are compounded for use, the waterproof and anti-permeability performances are improved, and tests show that the tensile adhesive strength of the sprayed mortar layer reaches 1.4 MPa after the sprayed mortar layer is not treated and cured and formed for 7 days, and is far higher than that of the existing anti-permeability mortar; and after thermal cycle and freeze-thaw cycle treatment, the tensile adhesive strengths respectively reach 1.1 MPa and 0.8 MPa, and good stability is achieved.
本发明涉及一种钢结构内墙用防水界面砂浆，属于建筑材料技术领域。该防水界面砂浆按照重量份计包括：水泥100‑800份、细石英砂200‑600份、分散乳液20‑150份、膨胀剂0.5‑5份、防水剂5‑50份、协效憎水剂5‑15份、减水剂2‑10份甲酸钙0.5‑5份；通过膨胀剂与快硬硫酸铝盐水泥相互作用，补偿砂浆凝固收缩，使砂浆层致密，防水剂和协效憎水剂复合使用，提高防水抗渗性能，经测试，喷涂砂浆层在不做处理，7d养护成型后拉伸粘结强度达到1.4MPa，远高于现有的抗渗砂浆，在热循环和冻融循环处理后，拉伸粘结强度分别达到1.1MPa和0.8MPa，具有良好的稳定性。
