Abstract - In the present day, much research is being done globally to identify a viable cementitious material to take the role of cement. For the purpose of partially or completely substituting cement in concrete, many materials are tested in this order: fly ash, silica fume, GGBS, Metakaolin , Micro materials, Quartz powder, etc. In this paper, a novel ultrafine material named Alccofine and cement made with biobased materials might have lower CO2 emissions. Recently, it has been known as alccofine, is an efficient partial replacement for cement. Here, cement is partially replaced in self-compacting concrete by substituting 10% of alccofine The optimum percentage of alccofine content is considered for the research. Fresh and hardened properties of SCC and self- compacting concrete (SCC) were investigated for the mix and control one. The results showed that all tested properties have similar results of conventional SCC for alccofine. %. Where, slump flow diameter (SFD), compressive strengths and split tensile strength for alccofine were 550 mm, 38.66MPa and 3.6 MPa respectively achieved at 35% ratio of WS. Flexural behaviour of reinforced concrete beam using this  alccofine is studied and compared with conventional SCC beam. Hence obtained similar results of conventional SCC.

Key Words: Alccofine,mineral admixture, Flexural stength.
