Review on crushed glass fine aggregate in concrete

Abstract

In order to reduce the utilization of land filling among waste management nice emphasis is being placed on waste reduction and utilization. Every year within the India approximately 2.5 Mt of waste glass is made and about half this waste isn’t reusable. Thus alternative routes got to be found for using waste glass and one risk is to use it among concrete as a replacement for cement and/ or mixture.

In the analysis programme concrete mixes were tested that had third, 25%, five hundredth and 100% of the fine mixture replaced by crushed waste glass. All glass was originally in bottle kind and was crushed to supply ‘sand’ that had a grading curve more-or- less a twin of fine mixture obtained from a billboard provider. 3 colors of glass were studied, i.e. flint (clear), amber and green. Concretes were conjointly created that contained a combination of colors (in proportion in keeping with the load of every sort of waste glass made annually among the India) and conjointly a combination of unwashed waste glasses. The concrete combine adopted for investigation, i.e. 1:2:4, was selected  due to its wide use among business, and every one concrete was created with a water: cement content of 0.6 while not the addition of plasticizer or ASR-retarding agents. The suite of laboratory tests included; slump, flow, initial and final setting time, unbearable pulse rate, water absorption by immersion and capillary action rise, ASR measuring (volumetric and linear), compression strength at ages from seven days to one year.

Techniques of developed digital imaging and process are applied to the glass mixture to quantify numerous particle form factors, i.e. ratio, proportion concavity, Riley inscribed globularness and surface texture index. Applied mathematics analysis has been accustomed compare the distribution of particle forms gift among the fine mixture materials utilized in the experimental work. Dimensional changes (in 3 orthogonal directions) were measured as concrete cubes hardened over a amount up to one year. The length changes of concrete prisms were conjointly measured over identical amount of your time. The resultant knowledge indicated that a fine mixture that comprised twenty fifth glass and seventy fifth sand would be categorized as “non-expansive”, i.e. identical because the sand on its own.
