Modification of Lime-Cement Plaster by Introducing Mineral Admixture in Advance

Abstract: Lime-cement plaster sees widespread use as a building material. People know it for its ability to last, let air through, and be easy to work with. But adding natural ingredients can make it even better, turning it into a more eco-friendly and costeffective option. This research looks at what happens when you mix cow dung into lime cement plaster. For years, people have used cow dung in earth-based building. It's full of plant fibers and tiny living things. Builders value it because it helps things stick together, keeps water out, and fights off germs. This study looks at how well plaster works when mixed with different amounts of cow dung. It checks how easy the plaster is to use, how long it lasts, how well it keeps out water, and how well it insulates against heat. The results show that adding cow dung makes the plaster more flexible and less likely to crack while still keeping its strength. It also improves the plaster's heat retention capabilities and serves as a natural alternative to synthetic additives. The study concludes that cow dung could be a suitable natural supplement to lime-cement plaster. This supports friendly manufacturing practices and reduces reliance on chemical-based additives.
