The practice of having their products tested periodically is becoming very general among the producers of concrete masonry units. Since in a few cases, products manufacturers have reported that uniform results were obtained in one laboratory while variable results were obtained from another and since occasionally reports have been received where cardboard, wood or similar materials mere used for capping purposes, the committee decided to give further study to that portion of our Standard Specifications for Concrete Building Block, Building Tile and Brick which relates to the testing of these units for compressive strength.
