石膏在蒸养粉煤灰硅酸盐混凝土(以下简称粉煤灰混凝土)中用量虽然不多,然而对粉煤灰混凝土的各种性能却有很大的影响。因此探讨石膏对粉煤灰混凝土性能的影响,从而正确地评价和使用石膏,对于生产或理沦上来说都是很有意义的。我们对石膏用量与粉煤灰混凝土一些主要性能的关系较为系统地进行了一些试验研究,着重探讨了下列几个问题:1、石膏对粉煤灰混凝土蒸前性能的 Although the amount of gypsum in steamed fly ash silicate concrete (hereinafter referred to as fly ash concrete) is not large, it has a great influence on various properties of fly ash concrete. Therefore, the effect of gypsum on the performance of fly ash concrete is explored, so that the correct evaluation and use of gypsum is of great significance for production or management. We systematically conducted some experimental studies on the relationship between the amount of gypsum and some of the main properties of fly ash concrete, focusing on the following issues: 1. The pre-steaming properties of fly ash concrete
