Potential of Limestone Powder in the Production of Self Compacting Concrete
Abstract: Self-compacting concrete (SCC) is a cutting-edge building material. It's a smooth, durable concrete that fills the formwork completely. The SCC needs a lot of powder to perform well (mostly cement). However, increasing the cement content is impractical and may result in greater hydration heat and drying shrinkage. This project studies the effect of limestone powder (LSP) on the fresh and hardened appearances of SCC. To evaluate the samples with and …
