引言铝粉膨胀水泥(以下简称膨胀水泥),是当前国内现行的铸铁管等给水管道刚性接口膨胀水泥型填料的一种。它是冶金部包头建筑研究所,于1966年在原冶金部第八冶金建设公司初步试验与应用的基础上,经过反复试验与多次工程应用,于1970年最后定型的一种可以在施工现场自行配制的硅酸盐膨胀水泥。此种膨胀水泥密封填料(以下简称填料),首先在冶金部的基建及维修等部分
Introduction Expanded aluminum cement (hereinafter referred to as the expansion of cement), is currently the current domestic cast iron pipes and other rigid interface inflatable cement-based filler type. It is the Baotou Building Research Institute of the Ministry of Metallurgy. Based on the preliminary tests and applications of Eighth Metallurgical Construction Company of the former Ministry of Metallurgy in 1966, after repeated experiments and multiple engineering applications, it was finalized in 1970 at the construction site itself Preparation of silicate expansion cement. This expansion of cement sealing filler (hereinafter referred to as packing), first in the Metallurgical Department of infrastructure and maintenance and other parts
