Research on preparation of particles by crushing the waste glass which contains lead and the addition technique in concrete

Abstract

Untreated leaded waste glasses will pollute the environment which can release lead ions. Which is can be solidified into the concrete after being broken. Then the pollution problems could be solved, and the concrete slabs would radiation protection specialty of be increased. In this paper, the entire process of the crushing of waste glass which contains lead and its addition technique in concrete could be designed and researched after the FEM and EDEM analysis. A new double toothed roll crusher was studied base on the traditional crashers in this paper, and its work mechanism, structure and technique characteristics were introduced to crash the glass into the specified size. The morphological structure and optical transparence of the particles could be watched through a wide depth of field microscope.
