There are a lot of admixtures with different uses in the construction industry but it is not easy to choose the suitable admixture.
The (conplast Wp100), (sika grout 214) with (2%, 4%, 6%) and (5%, 15%, 30%) respectively have been used by weight and subistution of cement to the concrete mixture using (10) mm maximum size of coarse aggregate.
The results showed increasing in (compressive, strength, splitting tensile strength, dry density) and reduction in absorption by (29.4%, 21.5%, 18.3%) and (37.2%) respectively for (28) days test compared with the reference concrete mixture.
