Durability of Calcium Sulphoaluminate (CSA) Composite Cement-Based Materials Made from Municipal Solid Waste Incineration (MSWI) Fly Ash

Abstract:

Municipal solid waste incineration (MSWI) fly ash was successfully used as a main raw material in sintering and preparing calcium sulphoaluminate (CSA) cement in laboratory. This work focused on effects of cement additives of MSWI fly ash, lime powder (LI), fly ash (FA), and slag powder (SL) on the durability of CSA cement-based materials. Compared with the hardened cement containing 10% MSWI fly ash alone, compressive strengths of samples containing 20% combined additives was improved significantly. When 20% combined additives were added the resistance to shrinkage, carbonation and sulfate attack was strengthened while the combined additives had negative effects on the resistance to water permeability.
