Cement-based grouting material for gas desulfurization tower and preparation method of cement-based grouting material
The invention relates to a cement-based grouting material for a gas desulfurization tower. The cement-based grouting material is prepared from the following raw materials in parts by weight: 365-400 parts of ordinary silicate cement 42.5, 25-75 parts of quick-hardening sulphoaluminate cement 42.5, 25-50 parts of a mineral admixture, 10-20 parts of a calcium sulphoaluminate and calcium oxide composite expanding agent, 490-510 parts of limestone sand, 8-8.5 parts of a composite additive and 130-145 parts of water. The cement-based grouting material has the advantages of high fluidity, high early strength, no shrinkage, alkali corrosion resistance and sulfate corrosion resistance, is used for grouting construction of a bottom plate and a foundation bolt hole of a gas desulfurization tower, enhances the durability of a gas desulfurization tower equipment foundation and a foundation bolt, prolongs the service life, and reduces the later maintenance cost.
本发明涉及一种煤气脱硫塔用水泥基灌浆料，原料按重量份包括：普通硅酸盐42.5水泥365～400份、快硬硫铝酸盐42.5水泥25～75份、矿物掺合料25～50份、硫铝酸钙氧化钙复合膨胀剂10～20份、石灰石砂490～510份、复合外加剂8～8.5份，水130～145份。本发明水泥基灌浆料大流动度、高早强、无收缩、耐碱腐蚀、耐硫酸盐腐蚀，用于煤气脱硫塔的底板和地脚螺栓孔灌浆施工，增强煤气脱硫塔设备基础及地脚螺栓的耐久性，延长使用寿命，降低了后期维护成本。
