Experimental Investigation of Using Ultra-Fine Glass Powder in Concrete
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 9
Abstract
The Ultra- Fine Glass Powder (UFGP) smaller than 0.075 mm (No. 200) produced from grinding and polishing edges on flat glass of different size and thickness, has been used instead of sand in different proportions which are 15%, 30%, 45%, 60%, 75%, 90% and 100%. It was found that there was a slight decrease in workability when the percentage of replacement decreased.The effects of UFGP on properties ofhardened concrete which includedry density, water absorption compressive strength and thermal conductivity are analyzed. The results of this study show that UFGP is determined to have a significant effect on increasing its compressive strength at 15%, 30%, and 45% , and there is a reductionindry density atup to ~ 45% . As for cost analysis and thermal conductivity test, this investigation is an environmental one by taking into consideration the fact that UFGP could be used to produce lightweight aggregate concrete without the need for high cost or energyloss.
