Abstract: Testing high-strength concrete (HSC) for compressive strength puts into doubt a certain number of concrete testing practices. First, most testing laboratories are equipped with loading capacity machines inadequate for testing 150 x 300-mm (6 x 12-in.) specimens, thus limiting HSC specimens to 100 x 200 mm (4 x 8 in.) in size.
Cylinder End Grinder. The Cylinder End Grinder grinds the faces of concrete cylinders plane and parallel to within ASTM C617, usually with just one pass of the diamond wheel. Compression testing can commence immediately after grinding without the use of capping materials. The machine's small footprint makes it perfect for most labs.

Sparingly spray the concrete surface you're going to be resurfacing with water so that you'll be applying the mixed resurfacer compound to damp concrete. Now simply use a squeegee to pull and push the resurfacer product evenly across the entire surface area of the concrete until you get a nice uniform thin layer.

The most common method for monitoring the strength of in-situ concrete is the use of field-cured cylinders. This practice has remained generally unchanged since the early 19 th century. These samples are casted and cured according to ASTM C31 and tested for compressive strength by a third-party lab at various stages.
To obtain samples for chemical testing, the cores can be placed in the Concrete Core Sample Grinder, and then ground back in successive layers, the grinding dust being collected for subsequent chemical analysis. The machine consists of a radial arm grinding head, which pivots about a horizontal axis, mounted on a solid steel support frame.
