某钢厂的设备地脚螺栓预留孔按设计要求,凡直径小于30毫米者,需用硫磺砂浆二次浇灌。用硫磺砂浆作锚固材料具有致密、不透水,快硬,强度高,耐腐蚀和施工浇灌性能好等特性,特别在抢修工程中有更明显的作用,是一种值得推广的新型锚固材料。一、原材料技术要求 1.硫磺:系硫磺砂浆的胶结料,工业品有粉状和块状两种,可优先选用粉状物。
The reserved holes for equipment anchor bolts of a steel plant are designed according to design requirements. Where the diameter is less than 30mm, secondary mortar shall be used for the sulphur mortar. The use of sulphur mortar as an anchor material has the characteristics of compactness, imperviousness, fast hardness, high strength, corrosion resistance and good watering performance in construction, and has a more obvious effect in the repair work, and is a new type of anchoring material worthy of promotion. First, the technical requirements of raw materials 1. Sulfur: Department of sulfur mortar cement, industrial products have two kinds of powder and block, can be preferred powder.
