摘要：In the present review, we have tried to define the different families of chemicaladmixtures used in the formulations of cementitious materials, namely: plasticizers,superplasticizers, setting accelerators, setting retarders, air entraining, etc…. We havealso presented the different families of each type of those polymeric admixtures andtheir mechanisms of action.These admixtures can be used either to improve the physicalproperties of the fresh cement paste including the workability, the fluidity, the settingtime (depending on the climatic conditions of its installation in winter and/or summer)and the water content, and used either to improve the mechanical performance of mortarand / or concrete in the hardened state, to know the compressive strength, the porosity,the capillary absorption, and the durability. Or the both at the same time, in the freshand hardened state, reduction of the quantity of mixing water and subsequentlyimproves its mechanical resistance of compression and its durability.
