摘要
粉煤灰基矿物聚合材料是粉煤灰绿色综合利用的有效途径之一,本文从粉煤灰原料性质、制备影响因素及材料形成机制三个方面出发,重点对粉煤灰中玻璃相含量定量研究、粉煤灰在碱性条件下的水解和缩聚两个过程研究进行了综述,提出了目前该类材料研究中存在水解与缩聚重叠导致研究困难等问题,给出了可采用化学方法大幅降低缩聚反应速率等思路,为该类材料的深入研究提供了方向。
The preparation of geopolymer from fly ash is one way of green comprehensive utilization.In this paper,research progress was reviewed from three aspects:character of fly ash,affect factors and formation mechanism,focused on the quantitative analysis of glass phase content,hydrolysis and polycondensation of fly ash under alkaline condition.Some problems in the research are put forward,such as the overlapping of hydrolysis and polycondensation,which could be resolved by decreasing the polycondensation reaction rate with chemical process.These researches would provide a direction for the further studies of fly ash based geopolymer.
