Abstract
Fly ash is the main solid waste discharged from coal fired power plant,and the fly ash is mainly used for concrete additive, and the added value is low.In order to improve the utilization value of fly ash, the research on the preparation of lightweight high strength ceramsite.At 1100 ℃, Lytag sintering new phase anorthite, at 1200 ℃, Shi Yingxiang dissolves into the sintering phase, Lytag sintering new phase augite, suitable calcination temperature control at 1100-1200 ℃ range.When the calcination temperature is increased to 1200 ℃, the cylinder pressure intensity reaches about 6.3 MPa, the volume density reaches about 1.6 g/cm3.When the P value is low, the sintering temperature of fly ash ceramsite is reduced, the ceramsite is easy to burn, when the P value is more than 10, the sintering temperature of fly ash ceramsite is too high, and the fly ash ceramsite is not easy to expand.关键词
