Mechanical Characteristics of Lightweight Concrete Enhanced by Fly-Ash and Steel Fiber
This research deals with production of light weight aggregate concrete by using clayey stone aggregate, normal material (cement , sand) and some of mineral admixtures (fly ash and steel fiber ).

| description | This research deals with production of light weight aggregate concrete by using clayey stone aggregate, normal material (cement , sand) and some of mineral admixtures (fly ash and steel fiber ). Many trial mix were doing some of these by weighing ratio and others by volumetric ratio . We get light weight aggregate concrete (LWAC) with 24.92 N/ mm2 compressive strength and we improved mechanical properties by adding same percentage of fly ash and steel fiber (0.5 ,1 ,1.5) % of each other as a percentage weighing ratio of cement content . compressive strength increased with (7.8 , 5.2 , 2.9) % , splitting tensile strength increased with (20 ,16.71, 12)% and flexural strength increased with (24.5 , 17.9 , 8) % when adding (0.5 ,1 ,1.5) % of each steel fiber and fly ash respectively. The practical results of the current study indicates that the using clayey stone to produce (LWAC) is success and we can improved mechanical properties of this (LWAC) was produced in this research by adding fly ash and steel fiber with previously percentage. |
