Chemical Composition of Cement: The relative proportion of three oxide compositions is responsible for influencing the various properties of cement, like lime, silica and alumina. An increase in lime content beyond a certain value makes it difficult to combine completely with other compounds. Consequently,
Chemical Admixtures. Chemical admixtures are the ingredients in concrete other than portland cement, water, and aggregate that are added to the mix immediately before or during mixing. Producers use admixtures primarily to reduce the cost of concrete construction; to modify the properties of hardened concrete; to ensure the quality of …
Hydration of cement. Hydration is the chemical reaction between cement and water that forms bonds and results in a solid mass. The main compounds in cement - C3S, C2S, C3A, and C4AF - hydrate to form calcium silicate hydrates (C-S-H gel), calcium hydroxide, and calcium aluminate hydrates. Hydration is affected by factors like …
