Abstract
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.
