三十年来,我国粉煤灰的研究与应用,取得了一定的成绩,建成了一批利用粉煤灰生产建筑材料的企业,培养了一支粉煤灰研究与应用的技术队伍,在节省粉煤灰处理费用,减轻环境污染等方面获得了相当好的社会经济效益。但是,在利用粉煤灰生产建材制品方面还存在不少问题,如投资效益差,粉煤灰的利用还不广泛等。产生上述问题的原因除了体制与管理方面等重要原因以外,许多人对我国粉煤灰的特点缺乏足够的认识也是很重要的。因此在厂址选择、产品方向、产品的质量与成本等方面带有一定的盲目性。近几年来,我们开展了粉煤灰基本性能的研究,获得了初步成果, In the past 30 years, the research and application of fly ash in China have achieved certain results. A group of companies that use fly ash to produce building materials have been built, and a technical team of fly ash research and application has been trained to save powder. The cost of coal ash treatment and the reduction of environmental pollution have achieved considerable social and economic benefits. However, there are still many problems in the use of fly ash in the production of building materials products, such as poor investment efficiency, the use of fly ash is not yet widely used. The reasons for the above problems are not only due to important reasons such as system and management, but also many people have insufficient understanding of the characteristics of fly ash in China. Therefore, there is a certain degree of blindness in terms of site selection, product direction, product quality and cost. In recent years, we have carried out research on the basic properties of fly ash and obtained preliminary results.
