| 要旨 | This study involves a proposal of an in-place testing approach for concrete with a penetration resistance device. The existence of low-strength concrete (≤ 9 MPa) in buildings in Bangladesh requires a rapid evaluation of concrete compressive strength which is possible by an easy in-place test method with the penetration resistance device. Three types of pins of different diameters and shapes were used among which 2.5 mm diameter sharp pin gave the best relationship. The effect of surface roughness on the penetration depth results is also investigated which was found negligible for 2.5 mm diameter pins. |
