Abstract

Natural sand plays a unique role in the mix proportion of road cement concrete, however, the stock of natural sand in our country is very limited. In order to find the material that can replace the natural sand without affecting the performance of the concrete, the paper compares the physical properties of iron tailings with natural sand and designs the proportion of road cementitious concrete with iron tailings instead of natural sand. The use of iron ore tailings can not only solve the problem of iron tailings storage, natural sand supply and raw material cost, but also turn waste into treasure, improve the environment and contribute to economic construction. On this basis, slump detection analysis, workability analysis and mechanical properties of compressive strength test results show that: the sand rate of about 24.4%, and the particle size of 0.15--0.30mm when the corresponding The amount of iron ore tailings corresponding to the best proportion of concrete mix.
