Investigating Concrete Properties with Partial Replacement of Cement by Alccofine and Eggshell Powder

In this study, we investigate the effect of substituting cement with Alccofine and eggshell powder on the strength properties of concrete. Cement production is a significant source of carbon dioxide emissions, prompting the search for sustainable alternatives. Our research aims to address this environmental concern by evaluating the potential of Alccofine and eggshell powder as partial cement replacements while maintaining or enhancing concrete quality. We prepared various concrete mixtures with a constant 10% substitution of Alccofine, combined with different proportions of eggshell powder replacing cement (ranging from 0% to 20%). Through thorough testing including compressive, split tensile and flexural strength assessments, we analyzed the mechanical performance of these mixtures. Our findings demonstrate that Alccofine and eggshell powder can effectively substitute cement in concrete, providing a more environmentally friendly option that improves material strength. However, further research is needed to optimize the mix proportions and assess long-term durability in diverse environmental conditions. Notably, combining eggshell powder with Alccofine presents a promising approach to enhancing concrete performance while reducing the environmental impact of cement production. This study contributes to advancing sustainable practices in concrete construction, promoting the use of eco-friendly building materials.
