WHAT! NO TEST CUBES, BEAMS, CYLINDERS, CORES FOR CONCRETE PAVED AREAS?

A new approach to the problem of checking the degree of compliance with strength requirements of the design of a concrete paved area has resulted from investigations into the resistance to pull out of rag bolts and other fixings built into the surface of concrete by various means. Tests are described which can be used to determine the acceptance test value for the paving where a small area of concrete of specified thickness is laid on a base typical of the which is used in the work. For this test it would be necessary to ensure that when the acceptance value was determined, the strength of the concrete was neither lower nor significantly higher than the specification called for. Two alternatives are described for making a suitable concrete for the trial slab. The acceptance value would be determined by measuring the pressure developed in the cell at the bottom of each hole in the test slab when failure takes place.
