Ferrochromium slag is a kind of porous aggregate with rough surface structure.Based on its influence on the structure of interface transition zone and bond strength,the modifier suitable for ferrochromium slag was designed by orthogonal test.According to the principle of wall building,ferrochromium slag was modified to reduce its crushing value and water absorption.The mechanism of modifying ferrochromium slag with modifier was studied.By effective improving the interface structure between ferrochromium slag and slurry,ferrochromium slag can be used as high-quality concrete aggregate,and a high-strength modified ferrochromium slag mortar was prepared.This study provided a theoretical basis for the large use of ferrochromium slag,with energy saving and emission reduction benefits.
