再论粉煤灰小型空心砌块(上)

Discussion again on small hollow flying ash block

通过分析粉煤灰小型空心砌块胶凝材料结石的矿物组成,确认其并非是粉煤灰混凝土制品,而是粉煤灰硅酸盐混凝土制品。指出自然养护粉煤灰小型空心砌块与粉煤灰“免烧砖”属同一类产品,不宜发展。再次建议修订行业标准JC862-2000《粉煤灰小型空心砌块》。

The author affirmed that small hollow fly ash block was not flying ash concrete product, but flying ash silicate concrete product by analysis of the composition of bonding materials. The author also pointed out that naturally cured fly ash block was the same type as fly ash unburned brick and should not develop further, suggesting to revise the industry standard of 'small hollow fly ash block'(JC862-2000).
