Study on the Thermal System of Microporous Cementitious Materials

Article Preview

Abstract:

Industrial residues--fly ash, carbide slag, desulfurization gypsum--of different proportions were used as raw materials to discuss the sintering characteristics and thermal effect of each proportion and their effects on porous cementitious materials. The properties of those materials were analyzed and the formula were calculated according to sulphoaluminate cement formulations . The sample were burned at different temperatures according to ceramsite-making method so that some hard water minerals and a microporous structure could be formed. By analyzing the content of and β-C2S in the burned sample using XRD, SEM and EDS and discussing the effects of different burning processes on porosity and water absorption rate of materials to know the sintering system. The results show that the material burned at 1250°C for 20 min has good thermal insulation properties and cementing properties.
