提高蒸养粉煤灰净浆制品抗收缩性能的有效途径

An effective way to reduce the shrinkage of steam cured no-aggeragate solid flyyash block

本文通过无骨料粉煤灰密实承重砌块的研制,认为要使无骨料粉煤灰砌块满足JC238—78规定的粉煤灰煤渣密实承重砌块的各项性能,可在原状粉煤灰中加入一定比例的磨细粉煤灰,再加入适当量的石灰、石膏,这将是达到这一目的的一个极为有效的途径。

In the present work, It was performed to develop a new type of block, that is, no—aggeragaie solid fly ash block. The results show that it is an effective way to reduce the shrinkage of steam cured no—aggeragate solid fly ash block by adding a certain proportion of ground fly ash to a mixture of fly ash, lime and gypsum, which is commonly used in manufacturing fly ash—cinder block. It is also believed that no—aggeragate solid fly ash block witn the same properties as those of fly ash—cinder solid block required by JC238—78 can be developed in this way.
