Design of wall materials based on waste glass regeneration

Abstract

With urban high buildings increasing in China, the demand for efficiency of wall insulation is getting more and more serious, especially in northeast and northwest China. However, thermal insulation wall in domestic is quite easy to produce cracks under external conditions, which greatly reduces life time. In this paper, we expand the discarded glass and mix aggregate and polypropylene fiber to improve the compressive strength of concrete to achieve green multifunctional concrete.Through the performance test of the expansive glass, we conclude that performances of expansive glass become best at the sinter point of 660°;Moreover, TiO2 added to the exterior wall coating can catalyze the degradation of nitrogen oxides and formaldehyde to purify the air. Non-toxic and harmless, the wall, with strong thermal insulation efficiency, is expected to replace the current building materials in order to produce and utilize massively.
