上海地区职工住宅建筑逐年增加,不但对墙体材料的数量提出了新的要求,而且必须提高砌筑墙体的劳动生产率,加快施工速度。几年来上海地区推广使用粉煤灰硅酸盐密实砌块收到了一定的效果。但是,密实砌块的重量还比较大;加之发电厂烧油后,制作密实砌块的主要原材料粉煤灰来源不足。因此,为了进一步贯彻落实毛主席关于“综合利用很重要,要注意”的伟大指示,经过调查研究,认为利 The increase in the number of residential buildings for employees in Shanghai has been increasing year by year. Not only has new demands been placed on the quantity of wall materials, but also the labor productivity of masonry walls must be increased and the construction speed must be accelerated. Over the past few years, the use of fly ash silicate dense blocks in Shanghai has received certain results. However, the weight of compact blocks is still relatively large; together with the burning of oil in power plants, the source of fly ash, which is the main raw material for producing compact blocks, is insufficient. Therefore, in order to further implement Chairman Mao’s great instruction on “Comprehensive utilization is very important, pay attention”, after investigation and research, we believe that
