Sclerometer tests on concrete

The sclerometer tests are NDTs that allow the estimation of the concrete quality on-site. The tests use a Schmidt sclerometer that measures the superficial hardness of the concrete from the recoil of an incident mass after the collision with the surface being tested. This recoil is then converted to a value of compression resistance through an abacus. The test must be carried out on homogeneous concrete surfaces and it usually involves the removal of the carbonated superficial layer by scraping before.
