Non-Destructive Testing of Concrete (NDT on Concrete) Non destructive test is a method of testing existing concrete structures to assess the strength and durability of concrete structure. In the non destructive method of testing, without loading the specimen to failure (i.e. without destructing the concrete) we can measure strength of concrete. Now days this method []What are Different Tests for Concrete Quality Check?There are various in-situ test conducted on hardened concrete, both destructive and non-destructive.
