Durability of Calcium Sulphoaluminate (CSA) Cement-Based Materials from Municipal Solid Waste Incineration (MSWI) Fly Ash
The rapid growth of municipal solid waste has become one of the problems that plague Chinas future sustainable development.The decontami nation and disposal of municipal solid waste incineration (MSWI) fly ash has great significance to the promotion and application of MSWI technology in the world.In this work, MSWI fly ash was successfully used as a raw material in sintering and preparing calcium sulphoaluminate (CSA) cement in laboratory.Compressive strength and durability of the CSA cement-based materials were studied.The results show that compressive strength of the CSA cement has a similar developing trend with the Control Cem I which devdops fast at an early curing age but after 7d it increases slowly.The CSA cement-based materials are well in resistance to dry shrinkage, carbonation, and water permeability.
