What is a plastic admixture?

Answer 1

This is a general term most commonly used in relation to concrete. An admixture is simply a mixture of two or more substances. A plastic substance is simply one which may be formed or moulded with relative ease. In concrete terminology, a plastic admixture is a certain mixture which has properties of extended setting time or workability. This is desirable because there may be some time between the concrete being mixed at the factory works and it being laid or moulded on the required site. The term plastic admixture usually refers to the substances added to ordinary concrete (additives).

Answer 2

A plastic admixture is a material added to concrete or mortar to improve workability and reduce water content while maintaining the desired strength and durability of the mixture. It helps in making the concrete easier to place or spread without compromising its performance characteristics.
