Influence of glass powder silica fume and scrapped ceramic waste on the mechanical properties of concrete

Abstract

Carbon dioxide emissions from cement manufacture have a substantial environmental effect. The massive energy usage in the cement manufacturing process is also an issue. India is dealing with a major energy problem. Cement prices are rising on a daily basis. Furthermore, the usage of waste for the disposal and recovery of natural concrete components might harm the environment. Using trash not only decreases cement production and hence energy consumption, but it also helps to safeguard the environment. The goal of this study is to investigate the characteristics of concrete utilizing silica fume as a partial substitute for cement and glass powder in lieu of fine aggregate. These waste materials were used to replace some of the cement in the concrete samples, and their compressive, flexural, and split tensile strengths were assessed. According to the results, the addition of glass powder and silica fume improves the mechanical qualities of the concrete, but the addition of discarded ceramic waste has the reverse impact. Furthermore, the combination of glass powder and silica fume outperformed each waste item alone. The trials were carried out using Concrete Mix M40, which had been modified by substituting 40% of the coarse aggregate with waste ceramic aggregate, 20% of the fine aggregate with glass powder, and 10% of the cement with silica fume cement. Following tests of the concrete's compressive, split, and flexural strengths at 7, 28, and 28 days, the appropriate replacement dose was considered. The load-bearing capability of the beams is approximately the same as that of conventional beams throughout the board for the 20% replacement levels applied. The research comes to the conclusion that natural coarse aggregate may be used in place of scrapped ceramic aggregates (SCA) in concrete. Other beam specimens and typical beam specimens (CM) deflected more with load than a beam specimen with 10% SF, 20% GP, and 10% SCA. Modern technology allows for the production of lightweight, high-strength concrete at a low cost. When compared to CA, SCA lowered aggregate weight.
