STRENGTH TESTING OF CONCRETE PAVERS

This paper aims to show that the tensile splitting test is more meaningful than the compressive strength test for evaluating the strength of concrete paving blocks. Its discussions and findings are based on research on testing concrete pavers from a production line, which were manufactured with 'dry' concrete. 888 individual determinations were performed on 23 samples of concrete paving blocks, obtained from eight regions of South Africa. The following test methods and Standards were used: (1) SABS 1058 Compressive strength of concrete paving blocks (260 determinations); (2) cube compressive strength determinations (255 determinations); (3) BS 1881 Tensile splitting test with a 6mm wide edge (295 determinations); (4) BS 1881 with a cylindrical edge of radius 100mm (36 determinations); (5) BS 6717 Compressive strength on concrete paving blocks (24 determinations); (6) NZS 3116 Compressive strength on concrete paving blocks (24 determinations); and (7) ASTM C936 Compressive strength on concrete paving blocks (24 determinations). The Student's t method was used to test the comparisons statistically. It was found that the tensile splitting test to determine the quality of concrete paving blocks can be implemented by a considerably cheaper test apparatus.
