Distinguish, differentiate, compare and explain what is the differences between Chemical Admixture and Mineral Admixture Concrete are as follow:
Comparison and Differences between Chemical Admixture and Mineral Admixture Concrete
Chemical Admixture — These admixtures have formulated chemical composition and these are used for certain proportions of concrete. They are mainly used to reduce the cost of concrete construction. Chemical compounds are added to concrete in very small amounts for purposes such as entertainment of air, plasticization of fresh concrete mixtures, or comic.’ of setting time Certain admixtures, such as pigments, pumping aids and expansive agents are used only in extremely small quantity and are usually batched by hand it,’ premeasured containers. Chemical admixtures are used in construction industry for building durable. strong and water-proof structure.
Mineral Admixture — Mineral admixtures are usually added to concrete in large quantity. They can improve the resistance of concrete to thermal cracking alkali-akorgate expansion, and sulfate attack. Natural pozzolanic material and industrial byproducts, such. fly ash and slag are commonly used mineral admixtures. These admixtures do not have any binding property by themselves but these are react with calcium hydroxide liberated on hydration of cement to produce cementing compound with good binding properties. These are added in large amount to improve performance of the concrete and reduce the cost of construction.
