Study on Modification of Fly Ash for New Ultra-Early Strength Phosphate Repair Material
The incorporation of fly ash into phosphate repair materials can effectively improve their properties.This study experimentally investigates the influence of fly ash content on the setting time,strength,and shrinkage properties of phosphate repair materials.The results indicate that the addition of an appropriate amount of fly ash can delay the setting time.However,as the content of fly ash increases,the strength decreases to some extent,but it can reduce the drying shrinkage of the phosphate repair material.
