A study on compressive strength, static and dynamic elastic modulus of self-compacted concrete contained nanomaterials

In this study, the influence of different kinds of nanomaterials such as Nano oxides of Silica (NS), Aluminum (NA) and Copper (NC) on compressive strength (f’c), static elastic modulus (Ee), relationship between f’c and Ee and the relationship between static and dynamic elastic modulus (Ed) of self-...
