Concrete Strength Testing

Strength Testing

There are numerous methods available to measure the in-place strength of concrete. Each test method has specific uses and limitations and it is important that the best method be used for each application.

Strength testing utilizing rebound hammers is specified in ASTM C805. The rebound hammer test has been widely used since the mid-20th century and is most popular for its simplicity of use and for field applications. Humboldt’s rebound hammers accurately measure compressive strength of concrete which ultimately determines the load-bearing capacity and durability of concrete structures.

Ultrasonic testing is an excellent method to monitor the strength and deterioration of concrete, which may have occurred due to age, fire, frost or chemical attack. Ultrasonic testing can also perform thickness measurements, locate localized defects such as voids, honeycombing and the detection of objects such as pipes and ducts.

Windsor Probe concrete strength testing is performed by using a hardened steel probe with a concical tip to penetrate the concrete surface which is fired into the concrete with a gun using a cartridge. The strength of the concrete is determined by the depth of penetration of the probe. The Windsor Pin is a non-explosive version of the device, spring-loaded to drive a steel pin into the concrete or mortar.
