HIND AGRICULTURAL RESEARCH AND TRAINING INSTITUTE C oncrete is widely used construction material in the present industry. The concrete consists of cement, fine aggregates and coarse aggregates. Concrete is strong in compression and weak in tension. Also the cement manufacturing industry on an average emits 7 per cent of greenhouse gases to earth’s atmosphere which leads to global warming (Singh and Jain, 2018). The use of river sand as fine aggregate tends to exploitation of natural resources which cause lowering of water table. In order to address these environmental affects extensive research is ongoing into the use of cement replacements, using many waste materials [like Is glass powder a waste or boon for concrete : A thought provoking study Bhupinderjeet Singh and Ritesh Jain Received : 15.01.2019; Revised : 06.03.2019; Accepted : 22.03.2019 ABSTRACT : The utilization of glass powder in the present days as a substitute for cement is to enhance the strength of concrete. The glass powder was supplanted by 0 per cent, 5 per cent, 10 per cent, 15per cent and 20 per cent for 7 and 28 days for cubes for compressive strength. The utilization of concrete and generation of cement makes considerably more ecological issues and costlier. To maintain a strategic distance from such conditions, the substance of cement is decreased and replaced by glass powder which lessens cost and builds quality and durability of cement. Concrete is the most broadly utilized and adaptable structure material which is commonly used to resist compressive powers. By the addition of some pozzolanic materials, the different properties of cement viz., workability, durability and quality can be improved (Singh and Jain, 2018). Glass may be added in crushed form or in powder form along with the addition of admixtures/plasticizers or without addition of any of the alternate materials in the nominal concrete (Singh and Jain, 2018). Accordingly, a study about usage of glass powder has been made in this paper to include it in concrete as an ingredient so that the best possible usage may be used in the concrete with a partial replacement. From the test the glass powder concrete gives more strength as compared to conventional concrete and can be used for normal construction process.

Waste glass is a non- biodegradable material and disposal of waste glass into the land results in the soil pollution (Jangid and Saoji, 2014). So to avoid these disposable problems waste glass is used as partial replacements of coarse and fine aggregates. In cement manufacturing a replacing aggregate with glass waste will reduce unit weight of the concrete, under laboratory studies glass has high silica content on its feasibility condition. Use of waste glass in concrete makes the structure denser, this results in reduction of water absorption and improves durability of concrete (Jangid 15/19 (16) See end of the Paper for authors’ affiliation Correspondence to : Bhupinderjeet Singh Department of Agricultural Engineering, Punjab Agricultural University, Ludhiana (Punjab) India Email : singhbhupinderjeet 096@gmail.com
