Admixtures are used in specialised concrete to enhance and modify its properties.These admixtures comprise a distinctive blend of chemical or mineral components that are incorporated into the concrete mixture to …
-
Admixture is added in concrete or mortar for increasing the rate of hydration of hydraulic cement and for shortening the setting time. Admixtures are added to the concrete batch immediately …
-
Retarding admixtures has little or no effect other than to delay the setting of the cement. They do not plasticize significantly and do not affect the water demand or other …
-
A chemical admixture can be added to concrete to achieve or modify its properties. Admixtures are added to the concrete, in addition to cement, water and aggregate, typically immediately before …
