Glass Waste as Fine Aggregate Filler Replacement in Concrete Addition of Superplasticizer
Glass has been made and used in various ways, such as bulbs, bottles, and cathode-ray tubes, all of which have a limited lifespan and are disposed of in landfills, causing multiple environmental concerns. Due to the physical and chemical similarities between glass and sand, glass waste can be used in concrete mixing by substituting glass waste for partial fine aggregates of sand. This study aims to determine the best percentage of glass waste as fine aggregates in concrete, both with and without a superplasticizer. The study looks at how varying percentages of sand substituted with glass trash affect the compressive strength of concrete. The first step of the experiment involved replacing fine aggregates with glass trash at a ratio of 15, 20, 25, and 0% as the control group. The second step entails combining the optimal percentage replacement from the first portion with superplasticizer at varying dosages of 0.8, 1, and 1.2% of the total cementitious weight. After 7 and 28 days of curing, the samples were subjected to a compressive strength test and characterization. According to the findings, samples with replacement percentages of 15, 20, and 25% showed better compressive strength than the control group sample, supporting the characterization result. In the case of the superplasticizer admixture, the compressive strength has risen considerably for each dose sample compared to the control sample. In conclusion, the research reveals encouraging findings for replacing sand with glass in concrete up to 20% by weight of sand, with the addition of a superplasticizer if higher strength is needed.
