Chemical admixtures are those, which are added after batching of concrete so that every separate admixture gives some important functions to the properties of concrete.

Mineral admixtures are those admixtures which are obtain from industries. Mostly mineral admixtures are residue of some industries and are used to replace cement and make concrete cheaper.

These are many factors which has strong influence on strength of concrete. Of these factors are not being considering during mixing then these air entraining admixtures may have some negative impact on properties of concrete.

Air entraining admixtures affects very widely the properties of concrete. Slump value of concrete increases by using air entraining admixtures, by using
