摘　　要：发展非烧结粉煤灰轻骨料是粉煤灰利用的一个较有效的途径。然而,非烧结粉煤灰轻骨料的性质与粉煤灰陶粒有很大区别。为了全面评价非烧结粉煤灰轻骨料的质量,必须注意下列与混凝土性能有关的问题:与混凝土中水泥浆性能的相容性;对混凝土中钢筋锈蚀的保护性能;混凝土的变形性能;高温下混凝土的性能以及混凝土的质量控制。The development of the non-sintered fly ash LWA is a more effective measure for the utilization of the fly ash. However, there is a great difference in the behavior between the non-sintered and the sintered fly ash LWA. For comprehensive evaluting the quality of the non-sintered fly ash LWA, the following problems concerning the properties of concrete must be considered: the compatibility of the behavior between the aggregate and the cement matrix; the corrosivity of the steel in concrete; the deformability of the concrete; the behavior of the concrete under high temperature and the quality control for the concrete.
