Utilization of Alumina Waste and Silica Waste for Geopolymer Production
This research studies the utilization of alumina waste and silica waste for geopolymer production. Alumina waste was obtained from aluminium thermal metallurgy industry, silica waste was obtained from silicone recycle industry in Thailand. This present study aimed at investigating the basic physical and chemical properties of waste materials and also the optimal proportion in geopolymer product...
متن کاملUtilization of Powdered Gypsum-Wallboard in Concrete
Two groups of concrete mixtures, one without sodium sulfate and other with sodium sulfate, as an activator, were made with recycled powdered gypsum-wallboard for this investigation. Group 1 concrete mixtures were made using up to 20% of ASTM Class C fly ash and 20% powdered gypsum while Group 2 contained up to 60% of fly ash and 20% of powdered gypsum by mass. Relevant properties of concrete we...

متن کاملthe potential of deinked waste paper sludge in gypsum fiberboard production
application of cellulosic fibers and minerals of deinked waste paper sludge has a great impression on utilization and characteristics of final product. this study was designed to produce use gypsum-fiber board from the dip sludge. the gypsum: sludge ratio was considered as 100:0, 90:10, 80:20, 70:30 and 60:40. two types of gypsum boards were prepared with fixed 12 mm thickness and cold pressing...
متن کاملUtilization of different waste proteins to create a novel PGPR-containing bio-organic fertilizer
High-quality bio-organic fertilizers (BIOs) cannot be produced without the addition of some proteins, while many waste proteins are haphazardly disposed, causing serious environmental pollution. In this study, several waste proteins were used as additives to assist with the reproduction of the functional microbe (Bacillus amyloliquefaciens SQR9) inoculated into matured composts to produce BIOs....
