After the concrete specimens have been curing for a specific number of days [3, 7, 14 days], they are prepped by the lab for breaking. This involves either grinding the ends of the cylinder so that they are parallel or capping them. Grinding the ends of a break is done to ensure continuity in contact while the load is applied.
Concrete cylinder end Core cutting and grinding machine using a water hose, rinse the grinding dust and debris from the grinding compartment into the reservoir. It is important to clean the machine after each use, as deposits will build up inside the grinding wheel, enclosure, and lid.

Important steps in cylindrical grinding 1. Check the work for size to make sure grinding stock has been allowed, and the same time note any tapering of the work. 2. Inspect the work centers to see that they are clean and true. Select machine centers of suitable diameters to fill the work's centers properly.
The in-place strength of concrete cylinder at the location from which a core test specimen was extracted can be computed using the equation: (4) f cy = F l / d · f core where f cy is the equivalent in-place concrete cylinder strength, f core is concrete core strength, and F l/d is the strength correction factor for aspect ratio.
