石灰炉渣三合土在国内已被普遍推广使用。它是利用工业废料炉渣、石灰和黄粘土按一定比例配合而成的。具有整体性、水稳定性好,施工简便,后期强度大,成本低等优点。同时在成型后即使遇雨亦不受影响,特别是对不产砂石材料的城市既可代替价格昂贵的石料,又解决了工厂废料的堆置问题。因此市政部门喜欢采用。但是到目前为止,尚没有统一的操作规程,就武汉市来说,各公司、各工地、各区的施工方法亦不一致。笔者最近参加了几个工程的施工,进行了比较,并访问了有关技术人员,综合了各工程施工中的优点,现介绍如下,供参考:
Lime slag triptych has been widely used in China. It is the use of industrial waste slag, lime and yellow clay with a certain percentage of the result. With integrity, water stability, construction is simple, late strength, low cost and so on. At the same time, even if it encounters rain after forming, it will not only replace the expensive stone material but also solve the problem of the factory waste material stacking. Therefore, municipal departments like to use. However, up till now, there is no unified code of practice. For Wuhan, the construction methods of various companies, work sites and districts are also different. I recently participated in the construction of several projects, conducted a comparison, and access to the technical staff, the advantages of the construction of a comprehensive, are presented below, for reference:
