Compressive Strength assessment of self-compacted concrete with Nano materials using ultrasonic pulse velocity method

In this paper the compressive strength (f’c) of self-compacted concrete (SCC) containing Nanomaterials (NM) is evaluated by non-destructive ultrasonic pulse velocity method. This study involves about 13 different mixtures containing Nano oxides of Silica (NS), Aluminum (NA) and Copper (NC) with amou...
