Waste Glass Powder as a Partial Replacement of PPC

Krati Gahoi, Rajeev Kansal

Abstract: Concrete is the mixture of various materials coarse aggregate, fine aggregate, cement & water, each of them is mixed in various proportions to achieve specific strength. Cement being the most important material plays an important role in the manufacturing of concrete. Cement possesses binding properties and provides strength. The concrete consumes various non-renewable sources & their consumption increase the threat of sustainable concrete. Around 7 % of greenhouse gases are emitted by cement industry in the earths atmosphere. Today various researchers are studying the use of supplementary material which posses cementitiuos properties for example fly ash, silica fumes, blast furnace slag etc. Just like other waste products like fly ash, silica fume etc. glass powder is also used as a partial replacement of cement. Waste glass in the form of fine aggregate or as alternative cement can be used. Researchers has investigated that glass posses a pozzolana properties due to increase in silica content, so it can be replace cement to some degree and can improve the strength and also increase the durability of concrete. In this study the glass powder replaces the Portland pozzolana cement from 0 % to 25 %, at interval of 5 % and the various properties of concrete is tested. At 3rd, 7th and 28th day the compressive strength is measured while the flexural strength is measured at 28th day. In addition to this the slump value, the water absorption and the cube density were also measured and all the properties were compared with the conventional concrete. The results concluded that the waste glass powder can be used as a partial replacement of cement.

Keywords: Pozzolana Portland cement, waste glass powder, compressive strength, density, water absorption
