Utilization of Phosphorus Slag and Fly Ash for the Preparation of Ready-Mixed Mortar

Abstract:

Phosphorous slag and fly ash were used as raw materials for the preparation of ready-mixed mortar, and a series of technological parameters, such as phosphorus slag content, fly ash content, and chemical activators were investigated based on the compressive strength and setting time of specimens in this paper and the performances of products were also tested. The results showed that the optimal mix proportion for preparing ready-mixed mortar (M10) is as follows: cement 5%, phosphorous slag 10%, fly ash 10%, sand 75%, water reducer 1% and chemical activator 1%. The consistency, water retaining, setting time, 28d compressive strength, 14d bond strength and 28d shrinkage meet the requirement of Chinese standard GB/T 25181-2010.
