| Abstract | ||
| Abstract The reaction product of linseed oil fatty acid and diethano l amine was used as a concrete admixture. It has multiple benefits; it reduces the required water content for a concrete mixture by about 13% (by adding admixture equal 0.1% of cement content) and also slows the corrosion of reinforcing steel in concrete. By reducing the water / cement ratio a higher compressive strength is produced without increasing the amount of cement. It acts as an accelerating admixture which reduces initial and final setting time rate of concrete. Also it can be used as corrosion inhibitor which imparts a defensive strategy for concrete structures in marine atmosphere, high way bridges and others. This admixture is classified as F group according to ASTM C 494. In the present study, the authors will concentrate on the effect of the admixture on improving the mechanical properties of concrete. The comparison of the new admixture and a commercial one on the concrete properties showed that , this admixture improved mechanical properties by about 20% more than commercial admixture. | ||
