Abstract: The aim of this research is to investigate the effect of different proportions of nano silica and polyethylene glycol 400 (PEG 400) on self-compacting high strength concrete. Finding out optimum content of nano silica, concrete mixes of proportions 0%, 1%, 2%, 3% of cement content (NSSCC). By substituting the optimum nano silica dosage in self-curing concrete mixes which contains PEG 400 in 0%, 0.5%,1%, 2%, 3% proportions of cement (SCSCC). The physical properties are measured in time and diameter for slump flow, V- funnel tests. Mechanical properties are performed in terms of compressive strength, split tensile strength and flexural strength. The experimental results are almost satisfied the EFNARC guidelines. Fresh properties of concrete has decreased as increasing nano silica proportions. Mechanical properties of SCSCC are less compared to NSSCC.
