Properties of Self Compacting Concrete Containing Limestone Powder as Replacement of Sand

Abstract

In this paper the properties of Self Compacting Concrete (SCC) was investigated using white cement and lime stone powder as fine aggregate instead of sand. All mixtures were proportioned with constant amount of (cement, lime stone powder, coarse aggregate and silica fume). While the glass powder, ceramic powder and glue were used as additives in different proportions from cement weight. The study focuses on comparison of fresh properties for self compacting concrete using two types of testing flow test and J-ring test. Whereas the hard concrete properties tests limited to compressive strength.The results leading to some developing in fresh properties and hard properties of self compacting concrete due to adding the additives. The best spread ability obtained at adding glue (4%) from cement weight. While the glass powder and ceramic powder affect to hard properties, adding ceramic powder increased the compressive strength at rates between (10-20) % from cement weight and adding glass powder modified the compressive strength at rates more than (20)% from cement weight.
