固硫底渣提高防水砂浆抗渗性的研究

Study on Impermeability Improvement of Waterproofing Mortar by Solid Sulfur Residue

通过回收燃煤电厂产生的固硫底渣,应用于水泥基材料中制成防水砂浆,研究了固硫底渣对防水砂浆抗压强度、体积稳定性和抗渗性的影响,并对其影响机理进行了探讨。结果表明:固硫底渣在一定用量范围内能够有效地改善防水砂浆的抗压强度,减小收缩性,提高抗渗性。

Solid sulfur residue from coal-fired power plant is recycled and used in cement based material to produce waterproofing mortar. The article studies its influences on the compressive strength, volume stability and anti-permeability of waterproofing mortar. The results indicate that a certain amount of solid sulfur residue can effectively improve the waterproofing mortar＇s compressive strength, reduce its contractility and enhance the impermeability.
