本文专讲目前将大量制造的石灰火山灰质水泥(包括石灰烧粘土水泥,石灰煤渣水泥,以及类似的石灰凝灰岩水泥,石灰烧页岩水泥等)和石灰矿渣水泥的使用问题.至于个别地区由于原料条件可能制造硫酸盐矿渣水泥,天然水泥,或水硬性石灰来供给附近农村使用,这些水泥不在本文范围以内,但有些内容仍能适用,可以作为参考. 一、地方性水泥的主要优缺点:任何材料的优缺点都是相互比较得来的.下列优缺点是地方性水泥分别和矽酸盐水泥与石灰比较得出的.
This article focuses on the use of lime-based pozzolanic cement (including lime-fired clay cement, lime-slag cement, and similar lime-tuff cement, lime-fired shale cement, etc.) and lime-slag cement currently being mass-produced. Conditions may produce sulfate slag cement, natural cement, or hydraulic lime for use in nearby rural areas. These cements are not within the scope of this article, but some of the content is still applicable and can be used as a reference. I. Main advantages and disadvantages of local cement: Any The advantages and disadvantages of the materials are derived from comparison with each other. The following advantages and disadvantages are derived from the comparison of local cement and silicate cement with lime.
