5.2 For a given concrete mixture the rebound number is affected by factors such as moisture content of the test surface the type of form material or type of finishing used in construction of the surface to be tested vertical distance from the bottom of a concrete placement and the depth of carbonation. These factors need to be considered in interpreting rebound numbers.

Proper use of the Rebound Hammer . Updated to reflect the changes to ASTM C805 . The Rebound Hammer has been around since the late 1940’s and today is a commonly used method for estimating the compressive strength of in-place concrete. Developed in 1948 by a Swiss engineer named Ernst Schmidt the device measures the hardness of concrete surfaces
Purchase Hammer Drive Anchors. Before installing hammer drive anchors certain technical specifications must be considered to ensure that the correct size and length anchor are used. This page will provide you with the information you need to determine which sized hammer drive anchor is required.
Schmidt hammers or concrete test hammers are used to determine in-place strength of concrete. All of the concrete rebound hammers we carry below accurately measure compressive strength of concrete which directly determines the load-bearing capacity and durability of concrete structures.

The operation of the rebound hammer test is shown in the figure below. During the test when the plunger of the rebound hammer is suppressed against the surface of concrete a spring controlled mass with constant energy is made to hit the concrete surface to rebound back.. The force of rebound which is a measure of surface hardness is measured on a graduated scale.
