PCE-HT-225A is a heavy-duty concrete hardness tester or concrete test hammer, also called a concrete rebound hammer or Swiss hammer, used to measure surface hardness and material compression strength. Suitable for use with concrete, rock and building materials, this rugged, manufacturer-calibrated rebound hammer is both easy to use and built to last.
The quality of concrete is judged mainly on the basis of compressive strength, since compressive strength is directly responsible for the structural behavior and durability of concrete constructions. The compressive strength is designated by a sequence of letters and numbers. For example, "B 25" is considered normal concrete with a compressive strength of 25 N / mm². There are many intermediate values up to the highest strength class of "B 55." Thus, using this concrete hardness tester, you can quickly, easily and accurately classify concrete strength.
