Partial Replacement of Coarse Aggregate with Waste Glass and Cement with Glass Powder
The depletion of natural resources is a widespread occurrence in developing nations such as India, attributed to the rising levels of urbanization and industrialization, which entail the construction of infrastructure and other facilities. The environmental and economic concern is the biggest challenge concrete industry is facing. The issues of environmental and economic concern are addressed by the use of waste glass as partial replacement of coarse aggregates in concrete. Cement was replaced by waste glass powder as 0%, 5%, 10%, 15%, 20% by weight for M-25 mix. The concrete specimens were tested for mechanical tests and durability (water absorption) at 28 days of age. The waste materials considered to be recycled in this study is amber glass (beer bottle). Glass was used to replace partially of coarse aggregates as 0%, 25%, 50%, 75%, 100% in concrete mixes. These tests included workability, flexural strength test, tensile strength, compressive strength and water absorption test. The compression test done at 7 days and 28 days. The other mechanical test done only at 28 days. It was observed that the compressive strength values are higher than normal concrete up to 25% replacement of coarse aggregate with waste glass and 5% glass powder and further increase in glass reduces the strengths gradually.
