Concrete >> Strength
James Instruments, Inc. : Windsor Pin
In-place strength test, brick, mortar, concrete
 

Measures the compressive strength of concrete, mortar and brick in-situ, quickly, accurately.

A non-explosive instrument, the Windsor Pin System uses a spring-loaded device to drive a steel pin into the concrete or mortar. The depth of penetration of the needle correlates to the compressive strength of the material under test. A removable chuck and a small pin size facilitate the testing of mortar joints; this is the only system for testing the in-place strength of brick mortar joints. Conforms to ASTM C-803.

Concrete >> Strength
James Instruments, Inc. : Rebound Hammer
In-place strength test of hardened concrete
 

Indicates the compressive strength of Hardened Concrete

Manual Test Hammers provide the most economical, quick and easy concrete compressive strength test in the field. It will also provide an indices of hardness and compressive strength for other construction materials. It conforms to ASTM C-805 and other international standards. A benefit of using manual rebound hammers is, it is easy to use the manual calculations of the mean rebound number. 

Manual Test Hammer
Model W-M-250
Is the traditional instrument used for non destructive testing of hardened concrete. The easy to use instrument provides a quick and simple test for obtaining an immediate indication of concrete strength in various parts of the structure. The minimum verifiable strength is 1400 PSI (10 MPA) to approximately 9000 PSI (62 MPA). All concrete test hammers measure the surface hardness of the material they are testing; this is then correlated to concrete compressive strength.

The manual concrete hammer, aka rebound hammer, schmidt hammer, swiss hammer, sclerometer, is the most widely used non destructive instrument for compressive strength determination. However, it typically has the largest coefficient of variation; therefore the result should be verified with another non destructive test such as the V-Meter MK II.

Concrete >> Strength
James Instruments, Inc. : Anchor Test
For tensile strength of anchors
 

Measures a wide range of anchor strengths in construction materials

Two models, each with two different gauge capabilities enable precision readings over a wide range of applications - from light to heavy duty loads. The standard system has a pull stroke of two inches with an option to extend to four inches. The longer pull stroke allows for complete extraction of most fixings in one simple operation. A load diffusion bridge and pyramid are available to keep reaction loads away from the anchor point.

Shown above, from left, is the Super Anchor Test System with Load Diffusion Bridge, and the Standard System with the Load Diffusion Pyramid.
