我单位承建某研究院危险品仓库,设计地面为不发火面层,要求地面受物体撞击和摩擦时不发火花,表面平滑、耐热、不易燃。经过对几种原材料的试验比较,确定采用膨胀珍珠岩颗粒水泥砂浆做不发火地面,可提高工程质量,节约造价,操作也方便。经两年使用,除个别房间因基层沉陷出现几条裂缝外,大部分地面完好,能满足使用要求。 1.技术性能不发火膨胀珍珠岩颗粒水泥砂浆由轻质膨胀珍珠岩颗粒与325号矿渣硅酸盐水泥组成,作为地面面层。它与金属或石材等坚硬物体摩擦、撞击时,
Our company has undertaken the construction of a dangerous goods warehouse of a research institute. The design floor is an unfired surface layer. It requires that the ground is not sparked when the object hits and rubs, and the surface is smooth, heat-resistant and non-flammable. After comparing several kinds of raw materials, it was determined that the use of expanded perlite granular cement mortar as a non-fired ground could improve the quality of the project, save the cost, and facilitate the operation. After two years of use, except for a few cracks in individual rooms due to grassroots subsidence, most of the ground is intact and can meet the requirements for use. 1. The technical performance does not get angry Expansion perlite granular cement mortar consists of lightweight expanded perlite particles and No. 325 slag portland cement, as the ground surface layer. When it rubs against a hard object such as metal or stone, it
