Abstract
Sheet glass powder (SGP) used in concrete making leads to greener environment. In shops, near by Chidambaram many sheet glass cuttings go to waste, which are not recycled at present and usually delivered to landfills for disposal. Using SGP in concrete is an interesting possibility for economy on waste disposal sites and conservation of natural resources. This paper examines the possibility of using SGP as a replacement in fine aggregate for a new concrete. Natural sand was partially replaced (10%, 20%, 30%, 40% and 50%) with SGP. Compressive strength, Tensile strength (cubes and cylinders) and Flexural strength up to 180 days of age were compared with those of concrete made with natural fine aggregates. Fineness modulus, specific gravity, moisture content, water absorption, bulk density, %voids, % porosity (loose and compact) state for sand (S) and SDA were also studied. The test results indicate that it is possible to manufacture concrete containing Sheet glass powder (SGP) with characteristics similar to those of natural sand aggregate concrete provided that the percentage of SGP as fine aggregate is limited to 10-20%, respectively.
Highlights
During the last decades it has been recognized that Sheet Glass waste is of large volume and is increasing year by year in the Shops, construction areas and factories
The objective of this paper is to present the results of experimental investigations on Physical and Mechanical properties of concrete made with Sheet Glass powder concrete
The compressive strength test results for the concretes containing Sheet glass powder (SGP) as fine aggregates of cubes according to their age are very similar to each other
Summary
During the last decades it has been recognized that Sheet Glass waste is of large volume and is increasing year by year in the Shops, construction areas and factories. Using waste glass in the concrete construction sector is advantageous, as the production cost of concrete will go down [1]. Waste glasses are used as aggregates for concrete [2,3,4]. In Chennai there is a place called Chidambaram where most of the colored sheet glasses from windows are packed as a waste and sent to landfill. Very limited work has been conducted for the use of ground glass as a concrete replacement [7]. These waste storage disposals are becoming a serious environmental problem especially for Chidambaram where place disposal sites are lacking. There is a need for recycling more and more waste materials
