Abstract
This thesis reports on the workability and mechanical properties in term of compressive strength of a self curing concrete that contains fly ash to solve the problem of improper curing. In order to make the concrete cured by itself, a chemical called Polyethylene Glycol 400 is used where it helps in water retention throughout the concrete during curing process. Therefore the usage of water is not needed to cure the concrete to achieve its maximum strength. Polyethylene Glycol 400 is added to the concrete mix during mixing process and the concrete mix were left air cured in a room temperature after it has been molded. Superplasticizer is used in this project to increase the workability of the concrete mix because water cement ratio is reduced to minimize water consumption. Sustainability is very important and so fly ash which is the by-product of coal burning will help in waste management and reduce global warming caused by carbon dioxide emission from the production of cement. While Polyethylene Glycol 400 will solve the problem of improper curing that affect durability of concrete. This project is done to investigate the maximum compressive strength that can be achieved by a self cured concrete that contains fly ash to produce a new sustainable concrete.
