At current time, it is still difficult to produce SCC of constant quality at ordinary ready-mixed concrete plants because facilities and quality control of materials had not reached the required level. To improve manufacturing and handling, a viscosity agent (VA) was added to the mixtures. This paper will use different kind of viscosity enhancing admixtures (VEA) to produce different kinds of SCC and study the influence of VEA on self-compacting concrete. Different volume of coarse aggregates were employed to understand the materials influence on SCC .The results obtained indicate that using of viscosity enhancing admixtures (VEA) has proved to be very effective in stabilizing the rheological properties and consistency of self-compacting concrete .It is possible to reduce quality fluctuations in a fresh state for commonly available materials and production facilities. Creep & shrinkage was studied to understand the mechanical properties of these SCC.
