Fragmentary cement with fly ash and glass fibre reinforcement concrete’s strength

One of the most widely utilised building materials in the modern world is concrete. Cement is an essential part of concrete. Environmental concerns, in addition to deforestation and the combustion of fossil fuels, are very important in today’s society. For instance, a large amount of the greenhouse gas carbon dioxide, which accounts for 7% of the emissions of greenhouse gases into the atmosphere of the earth, is released during the manufacture of cement, a crucial component of concrete. It can be difficult to safely dispose of the glass waste that is produced in daily life because it has a short lifespan and is typically either stored or discarded after use. Solving the environmental issue brought on by industrial waste is now of great significance on a global scale. Recent research has shown that waste glass, when utilised in the proper fraction and grade, can be successfully used in concrete as a number of substitutes for the constituents of concrete. Due to its high SiO2 content, When made into a very fine powder, discarded glass demonstrates pozzolanic qualities. As a result, it can partially substitute cement in concrete and contribute to the development of strength. In this study, the effect of adding glass fibres in various volume fractions with 20%, 30%, and 40% fly ash substitution of cement was examined, along with its effects on compressive strength and split tensile strength in comparison to conventional concrete. Overall test results indicate that glass fibre can be used in concrete. According to the research, concrete reaches its maximum strength at 20% glass particles. After 20% glass fibre is added, concrete loses strength and weakens compared to the control. The impact of adding various volume percentages of glass fibres (20%, 30%, and 40%) is investigated in this study. Regarding the concrete’s split tensile and compressive strength, the impact of cement substitution was examined. According to the overall test outcome, glass fibre might be used in concrete. The outcome suggests that concrete’s maximal strength occurs at a glass powder content of about 20%. Concrete’s strength decreases and falls below that of the control at a level of 20% glass fibre
