Potential of usage of self compacting concrete with addition of recycled CRT glass for production of precast concrete elements

摘要

The electronic and electric waste (e-waste) quantities have been sharply increasing since the beginning of the 21st century. A significant portion of e-waste is composed of glass originating from the cathode ray tubes of the TV-set screens and computer monitors (CRT glass) which, due to the complexity of the recycling process and its chemical composition is very hazardous and represents a huge environmental problem. One of the modes of recycled CRT glass application is for making of self-compacting concrete (SCC). The paper investigated various properties of fresh and hardened SCC where CRT glass played the role of powdery mineral admixture. SCC made in such a way, with satisfactory physical-mechanical characteristics is suitable for production of various precast concrete elements. In order to monitor the durability of experimental concrete in actual conditions, several curbs were experimentally placed in the course of reconstruction of a street in Ni?.
