澳大利亚的建筑研究部门和高等学校对粉煤灰综合利用的研究取得了成功的经验,改变了粉煤灰是一种工业废料的传统认识,其中建筑企业是比较大的用户,对推进粉煤灰的商品化起了积极作用。澳大利亚认为用粉煤灰做水泥混凝土的掺合料,有如下几点好处:(1)粉煤灰掺合料对水泥混凝土拌合物有增塑作用,可以减少水的用量。粉煤灰作为混凝土的成分,在混凝土配合比的设计中予以考虑。由于减少了用水量,就可以在保证获得同 Australia’s architectural research department and colleges and universities have obtained successful experience in the comprehensive utilization of fly ash and changed the traditional understanding of fly ash as an industrial waste, in which construction companies are relatively large users and are advancing fly ash. The commercialization has played an active role. Australia believes that the use of fly ash as admixture for cement concrete has the following advantages: (1) The fly ash admixture has a plasticizing effect on the cement concrete admixture and can reduce the amount of water used. Fly ash as a component of concrete is considered in the design of concrete mix ratio. Since the amount of water used is reduced, it can be guaranteed
