以煤炭为燃料的电力工业日趋发展,粉煤灰的排量也随之增多,目前大部分尚未得到有效利用,大量的粉煤灰急待解决。虽然各地已有粉煤灰蒸养砖、粉煤灰砌块、粉煤灰无熟料(或少熟料)水泥等硅酸盐制品在建筑工程中应用,但因其早期及后期强度不高,收缩较大,抗碳化和耐磨性能较差等,对进一步扩大应用有一定影响。 The development of the coal-fired power industry has resulted in an increase in the volume of fly ash. At present, most of them have not yet been effectively utilized, and a large amount of fly ash has yet to be resolved. Although silicate products such as fly ash steamed bricks, fly ash blocks, fly ash non-clinker (or less clinker) cement, etc. have been used in construction projects, their early and late strength is not high. , Larger shrinkage, poorer resistance to carbonization and abrasion, etc., have a certain impact on the further expansion of applications.
