    The main objective of this research work is to examine the influence of combined use of various types of sand on the fresh and hardened properties of SCC. The types of sand used are crushed sand (CS), river sand (RS) and dune sand (DS). In addition, binary or ternary system mixture of these sands were also used. SCC mixes were made with constant content of cement and marble powder waste.
