上海硅酸盐制品厂利用原有的砌块生产车间改建了一条粉煤灰硅酸盐大型壁板生产线。用粉煤灰、石灰和石膏作胶结料,粉煤灰陶粒(或粘土陶粒)作骨料,经配料,搅拌、成型,蒸汽养护等工序制成的大型壁板,可用于大板建筑体系或现浇外挂建筑体系。壁板生产工艺是“反打”模板,迭模加压养护。养护制度:静停4小时,升温6小时,100℃恒温10小时,降温2小时。目前批量生产出的大极已用于上述建筑体系的住宅墙体中。据初步估计,使用这种墙
Shanghai Silicate Products Factory has used the original block production workshop to reconstruct a large-scale fly ash silicate board production line. Fly ash, lime and gypsum used as cement, fly ash ceramsite (or clay ceramsite) as aggregate, large-scale siding made by batching, mixing, forming, steam curing and other processes, can be used for large-scale construction System or cast-in-place building system. The siding production process is a “back-fighting” formwork, which is superimposed and pressurised. Maintenance system: stop for 4 hours, increase temperature for 6 hours, maintain temperature at 100°C for 10 hours, and cool down for 2 hours. The great mass produced at present has been used in the residential wall of the above-mentioned building system. According to preliminary estimates, use this type of wall
