Effect of nano-silica on the fresh and mechanical properties of conventional concrete

Nanotechnology is a new field of study that might eventually affect every other area of research and develop-ment. Many scientists have proposed various definitions of nanotechnology. Nano-materials could be a good product for the repair and rehabilitation of structures due to their particle size. It increases the packing density of the concrete and makes the concrete impervious easily. This research, checks the setting time, workability, compressive strength, splitting tensile, and flexural strength of different mix designs after the incorporation of nano-silica in conventional concrete at different ratios. The nano-silica incorporation varies from 0.0% to 3.0% by the interval of 0.5%. After the experimental investigation, the mechanical properties strength increases with the increment of nano-silica ingression in the concrete but it also decreases the workability of the concrete. After the experimental investigation, to propose a correlation equation between compressive strength and flexural strength is ffs = 7.44 + 4.93fcs.
