admixtures for microfine cement

A material other than water aggregates or cement that is used as an ingredient of concrete or mortar to control setting and early hardening workability or to provide additional cementing properties Admixtures of concrete are generally used to alter the properties of concrete such as increased workability or reduced water content acceleration or retardation of setting time acceleration
