Cathode Ray Tube (CRT) glass belongs to the group of wastes which are hard be recycled due their toxic metals content. Geopolymers relatively new environmentally friendly materials allow for use different types within matrix. The following paper combines both issues and presents a geopolymer mixture containing discarded CRT as replacement an aggregate. main goal is describe basic mechanical beh...

Abstract Influence of nano-glass powder on physico-mechanical properties geopolymer composite materials has been studied, in addition to studying their firing stability against high temperature from 500 up 1000 °C. For increasing mechanical, physical as well for metakaolin composites; Nano-glass was used. Alumino-silicate are kaolin, fired kaolin (metakaolin) and limestone all pass 75 µm. Mater...

Attempts should be made to recycle, re–use and utilize waste. Paper manufacturing is a complex industry involving multiple processes where different products are produced and large quantities of waste of primary, biological or de–inking origin are generated, waste water treatment sludge, primary sludge, and secondary sludge among them.1,2 The primary sludge is generated in the largest quantitie...

Abstract Hydrophobic metakaolin-based flat sheet membrane was developed via phase inversion and sintering technique modified through 1H,1H,2H,2H-perfluorooctyltriethoxysilane grafting agents. The prepared characterized by different techniques such as XRD, FTIR, SEM, contact angle, porosity, mechanical strength. Their results indicated that the wettability, structural, properties of confirm suit...
