Description
The free flow ability of fresh self-compacting concrete (SCC), capable of overcoming obstacles and penetrating
into difficult joints is one of the special properties that differentiate SCC from normal concrete. It can then be
rightly said that the fresh property of self compacting concrete (SCC) is the most important factor that
distinguishes SCC from conventional concrete. Due to the importance of this property to the overall performance
of self-compacting concrete, the tests of fresh SCC must be gotten right since any mistake will compromise the
essence of recurring to SCC in place of normal concrete.
This research attempts to enhance the flow-ability of SCC via replacement of cement with varying dosage of
limestone and super-plasticizer. To validate the improvement of SCC fresh properties, slump test is used to
assess workability, L-box test for passing ability and V-funnel test for filling ability. Test results analyzed with
statistical tools confirmed that the workability and rheological properties of self-compacting concrete can be
improved through the adoption of various dosages of limestone powder
