Concrete - Wikipedia

Concrete, usually Portland cement concrete (for its visual resemblance to Portland stone), is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently in the past a lime-based cement binder, such as lime putty, but sometimes with other hydraulic cements, such as a calcium aluminate cement or Portland CementTypes of Concrete Additives and Their Uses - Big D Ready Mix,Chemical Additives These are used to: Reduce the construction cost; Overcome emergencies at concrete operations Guarantee quality during mixing all through to curation process Modify the features of a hardened concrete; Mineral Additives They are used to: Increase concrete strength Economize on the mixture; Reduce the permeability levelsImprovement of Strength of Soil-Cement With Additives,(1 percent) a higher percentage of strength increase (50 percent) was obtained Con­ tinued study by Le Tellier and Wagner (1955) showed that considerable increase of strength could be effected on silt plus portland cement In 1955 a thorough review and investigation of the improvement of soil-cement with additives was undertaken
