The top pro sports teams and college athletic programs use Hammer Strength, which makes it an ideal choice for those who want top-tier training equipment. $1,446.00
In fact, there is about a variation of 15-20% in concrete strength measured by the method. Schmidt hammer is in not a standard test for acceptance testing of concrete strength. It is only a test used for estimating the strength of concrete in structure and it can hardly be considered as a substitute for compressive strength test.
Though these aren’t the absolute strongest anchors on the market, they can still support quite a bit of weight: up to 385 lbs in 4000 psi concrete, 340 lbs in C-9 block, and 250 pounds in brick Their sleeve design makes them pretty easy to install if you’ve properly drilled the holes with a hammer drill.
Humboldt's concrete rebound hammer provides a reliable, yet economical, alternative to the original schmidt hammer. It is designed for testing concrete 4" (100mm) or more in thickness with a maximum particle size less than or equal to 1.25" (32mm), providing a quick and simple test for obtaining an immediate indication of concrete strength in various parts of a structure.
Two buildings in Seattle, Washington, contain concrete with a compressive strength of 19,000 psi. The primary difference between high-strength concrete and normal-strength concrete relates to the compressive strength that refers to the maximum resistance of a concrete sample to applied pressure.

For the relatively small price, you are getting the electric hammer, a couple of chisels, a hard storing case, and a pair of gloves. The cost didn't affect the performance, though. This XtremepowerUS breaker boasts a powerful, single-speed operated 20 A motor that delivers up to 1900 BPM with incredible 55 J. Obviously, such tool can't be too lightweight.
Concrete and aggregate testing plays a vital role in the construction project by providing owners, designers, and contractors with valuable information throughout a project’s progress. Concrete & aggregate used in your construction projects must meet strict Australia …
The concrete maturity method is a proven in-situ strength estimation technique (ASTM C 1074) that accounts for the effects of time and temperature on the strength development of in-place concrete. It is used in construction world round to save time and money on projects.
to 20% (Concrete Institute of Australia, 2008). It is therefore recommended that the standard rebound hammer test be used as a method of testing variabil-ity of strength properties between concrete samples rather than as a substitute for standard compression testing. 2.2 Penetration resistance method Penetration resistance methods are invasive NDT
5.4 Relationships between rebound number and concrete strength that are provided by instrument manufacturers shall be used only to provide indications of relative concrete strength at different locations in a structure.

Dec 07, 2016· It represents the mechanical properties of concrete; for example, the 28 days compressive strength of concrete cylinders is the key parameter in most design codes (ACI 318-14, CSA A23.3-14). Strength is also considered (at least in the old school) a key factor for durability performance. On-site evaluation of concrete strength is a main ...
A fast and easy, non-destructive test (NDT) method of estimating the cylinder compressive strength is by the use of a Schmidt Hammer.. The Schmidt Hammer impacts on the concrete surface which causes the hammer to rebound giving a rebound number.
