Utilization of waste glass in alkali activated slag/fly ash blends: reaction process, microstructure, and chloride diffusion behavior
This study aims to investigate the chloride diffusion behavior of alkali activated slag and fly ash blends with different contents of waste glass powder (GP) addition. The reaction heat flow of alkali activated slag/fly ash/waste glass is characterized. The reaction products are determined by X-ray diffraction and thermogravimetric analysis (TGA). N2 adsorption analysis (BET) is used to evaluate the microstructure of samples. The accelerated chloride penetration test (ACPT) is applied to study the chloride resistance of the AAMs. Subsequently, the leaching test of chloride penetrated samples are conducted and ion chromatography is utilized to measure the chloride content in the samples. According to the BET results, the total volume of mesopores decreases with increasing GP content. The results of ACPT show that the increasing GP in AAMs shows an enhancement of chloride resistance.
期刊介绍：
The Journal of Sustainable Cement-Based Materials aims to publish theoretical and applied researches on materials, products and structures that incorporate cement. The journal is a forum for discussion of research on manufacture, hydration and performance of cement-based materials; novel experimental techniques; the latest analytical and modelling methods; the examination and the diagnosis of real cement and concrete structures; and the potential for improved cement-based materials. The journal welcomes original research papers, major reviews, rapid communications and selected conference papers. The Journal of Sustainable Cement-Based Materials covers a wide range of topics within its subject category, including but are not limited to: • raw materials and manufacture of cement • mixing, rheology and hydration • admixtures • structural characteristics and performance of cement-based materials • characterisation techniques and modeling • use of fibre in cement based-materials • degradation and repair of cement-based materials • novel testing techniques and applications • waste management
