HT-450 High-Strength Concrete Test Hammer | 20–110 MPa


Product Description

Mechanical rebound testing for high-strength concrete from 20 to 110 MPa

HT-450 High-Strength Concrete Test Hammer

Keywords: HT-450 high-strength concrete test hammer, high-strength concrete rebound hammer, concrete test hammer 20–110 MPa, C50–C100 concrete strength tester, bridge concrete rebound tester

The HT-450 high-strength concrete test hammer is designed to assess the compressive strength of high-strength concrete in building and bridge structures. Its 4.5 J impact energy and 20–110 MPa test range make it suitable for C50–C100 concrete. This mechanical concrete rebound hammer supports field evaluations of high-rise building components, bridges, and other concrete structures using the rebound method.
