Study Of Iron Tailings Concrete Small Hollow Block

With the decrease of resource on earth and the increase of environment consciousness of human beings, many countries treat tailing as secondary resource and widely carry on the study of utilization of ferrous tailing. Consequently, many achievements have been got, especially in the field of wall materials.Firstly, this paper uses variance analysis and other research means of statistics to study and definitize the best mix proportion ratio of ferrous tailing concrete. Its performance of mechanics and durability is studied. Meanwhile, its hydration theory and microstructure are analyzed with XRD and SEM.Secondly, this article studies the intensity theory of ferrous tailing small hollow blocks. Furthermore, the performance of mechanics and durability of these blocks and block structure built by these blocks is carried on.Thirdly, this paper discusses the calculation formulas, including those of compression intensity, shearing intensity and flexural intensity, and adjusts the coefficients in these formulas, which don't fit in with ferrous tailing small hollow blocks.
