Research on Mechanical Properties of Cement Mortar with Iron Tailings

Abstract

In this study the iron tailing was tested whether it can be used in the civil construction, Furthermore, specimen were made to test the mechanical properties of cement mortar with iron tailings substitute for part of cement. iron tailing sand has been ball mailed to specific fineness. The fineness of experimental iron tailing (sieve residue for the 200 mesh sieve) is 0.45%, 3%, 4.9%, 5.65%, 6.50%, 8.70%, 11.10% respectively.This paper show the influence law of different finesses of iron tailing powder on the Mechanical properties of cement mortar.
