Phosphorous slag, one of the pozzolanic active materials, is a by-product from production yellow phosphorous. In this paper, phosphorous slag was ground and adopted to prepare concrete as mineral admixture. Specific strength method used assess influences content on pozzolannic effects in with different age. The results indicated that increase age, were enhanced concrete. powder beneficial development long-term
