Experimental Study on Mechanical Properties of C40 Concrete Prepared with Phosphorus Tailings
In view of the shortage of cementing materials and river sand caused by rapid economic development,the effects of phosphorus tailings as cementing materials and fine aggregates on concrete were studied by experiments.The results show that the addition of 5%phosphorous tailing powder has the best effect as a substitute for cement.The addition of 40%phosphorus tail ore as fine aggregate to replace river sand has the best effect,and its mechanical properties have the most obvious improve-ment.It can be seen that phosphorus tailings can be added to concrete as a solid waste.
