The Effect of Grinding Time on the Performance of Gold Tailings Aerated Concrete

Abstract

The properties of aerated concrete are affected by many factors such as the nature of raw materials and preparation technology. Most Tailings are a kind of inert materials, which need to be mechanically activated to improve their activity when they are used as aerated concrete raw materials. In this paper, the performance of gold tailings aerated concrete under different grinding time was analysed by comparative experiment, so as to mainly reveal the mechanism of grinding-time-varying performance of aerated concrete. The results show that the gold tailings with a grinding time of 17 min show the advantages of the products in the preparation of aerated concrete
