Abstracts: Workability is an important property of fresh concrete because it affects the quality of several aspects of the construction process, including finishing. Good workability provides indirect benefits to the hardened concrete as well, because full consolidation is easier to achieve. Workable mixtures that allow adequate consolidation greatly reduce the presence of large voids in the concrete, which can otherwise significantly reduce concrete strength.Increasing the water content will increase the flow and compactiblity of the mix, but can also reduce strength while increasing segregation, bleeding, and permeability. Therefore the main objectives of project are to maintain the workability of concrete without any change in quality of concrete using plasticizer and super plasticizer and to study on workability and compressive strength of designed mixed concrete. This project shows detailed information about workability and process involved in producing workable concrete based on the experiment that has been done in laboratory.
