几千年以来,房屋建筑绝大多数采用“秦砖汉瓦”。按湖北省统计八六年砖的产量为三千六百二十八亿多块,每年吞食粮田五千余顷。以江汉平原每顷田产粮7.5吨计,则每年少生产粮食七千五百余吨。可见损失之大。因此迫切需要有一种新型建筑材料替代。水泥木屑板正是这样一种可以替代秦砖汉瓦的新型建筑材料。我参加了水泥木屑板厂与砖瓦厂的建厂,现就我的认识作一比较。一、建设(只含生产线)水泥木屑板厂(以下简称板材)投资低于同规模砖瓦厂(按成品用于建筑物计算。建一条年产
For thousands of years, the vast majority of housing construction uses “Qin brick Hanwa.” According to statistics from Hubei Province, the output of bricks in 1986 was 368.2 billion pieces, and more than 5,000 hectares of grain fields were swallowed each year. Taking 7.5 tons of grain per hectare in Jianghan Plain, it will produce less than 7500 tons of grain each year. Visible loss. Therefore there is an urgent need for a new type of building material alternative. Cement chipboard is just such a new building material that can replace Qinhanwawa. I participated in the construction of a cement chip factory and a brick factory. I will now compare my understanding. 1. Construction (consisting only of production lines) Cement and wood chipboard plants (hereinafter abbreviated as plate) Investment is lower than that of brick and tile factories of the same scale (calculated on the basis of finished products used in buildings.
