Study on the Sprayed Concrete with Iron Tailings

Abstract:

This essay is the subject of national eleventh five support schemes: The analysis of key technology on emission reduction and comprehension utilization of solid waste from large iron ore mine (Number:2008BAB32B14). The purpose of this test is to replace natural sand with the same amount of iron tailings and find a new technology method to utilize iron tailings. Based on theory of the preparation of sprayed concrete, this experiment made ratio test with 20%, 40%, 60%, 80% and 100% iron tailings content, and finally achieved the result which met the engineering required, after multiple batches of laboratory tests. By studying mechanical properties of sprayed concrete mixing different proportions of iron tailings, the optimal ratio of iron tailings to replace nature sand have been gotten. The result indicates that with 20% iron tailings to replace nature sand, the performance of sprayed concrete is the best.
