建材工业鲜明的行业特点之一,就是物化转变的消耗量相当大。以水泥生产为例,据测箅,每生产一吨水泥需耗用石灰石1.0～1.2吨,以1.0吨计,即相当于要开采0.4立方米的矿体。
Building materials industry is one of the distinct characteristics of the industry, that is, the consumption of physical and chemical transformation is quite large. Taking cement production as an example, it is estimated that every ton of cement produced consumes 1.0-1.2 tons of limestone to 1.0 tonne, equivalent to 0.4 cubic meters of ore body to be mined.
