Experimental investigations on the damage of Portland cement concrete made with natural aggregates
Abstract As part of research on the fracture behaviour of concrete, a series of tests on large (3.00 m×3.50 m×0.12 m) concrete slabs has been performed. The crack propagated under the action of a load applied to a crack notch placed in the centre of the largest side. The dimensions of the damaged zone in the neighbourhood of the crack tip have been determined using three different techniques: strain rosettes, acoustic emission and sonic testing. Computations based on the crack length must take account of this damaged zone. The tests have shown that this zone is approximately 10 cm long and about 10 mm wide, which corresponds to the maximum size of the aggregates.
