Abstract
Aggregates occupy more than 60% of the volume of concrete, play a main role in affecting its fresh properties as well hardened properties. The main objective of this research is to produce Self Compacting Concrete (SCC) by using a new type of coarse aggregate (Burned shale) and locally available materials in our region such as sand, limestone powder and silica fume. Experimental programme was designed to characterize the properties of fresh and hardened SCC and   the performance of SCC under influence of a solution of sodium sulphate. Two cement content 450 kg/m3 and 550 kg/m3 were chosen in this research. Also silica fume was used addition with 10% and 15% of cement. Limestone Powder =10% of cement. Super plasticizer (viscocrete) was used addition with 3 % of the cement. Water cementatious ratio ranged from (0.25, 0.35). There different test methods to characteristics performance and properties of scc in the fresh state like  Slump-flow test  , V-funnel , L- Box , U box , Fill box .All the cube specimens of concrete mixes were removed from the curing tank before testing age about 2 hours to dry in laboratory. The Hardened Concrete  properties tests limited to compressive  strength  test after 7,28,90 days ,  using pulsive velocity apparatus and shemidet hammer inference  cube compressive strength, test was performed at 28 days.
