With the purpose of validating the compressive strength test result on half-unit specimen for concrete paving blocks quality control, experimental results on half-unit and whole unit blocks from 24 production batches were analyzed. The compressive strength results in whole unit was greater than in half-unit specimen, but they are connected by a form factor.
produce a hardened concrete block of the required minimum quality. The cost of the paving block will depend on the variations in the strength which is likely to be obtained and if the range of variations .Concrete Block Paving by A.J. Dowson S. Marshall & Sons Ltd, UK is reduced, then the costs of the material will be lower.
Oct 31, 2016· Compressive Strength Tests on Concrete Masonry Blocks. Eight blocks are taken to determine the average compressive strength of concrete masonry block. The blocks should be tested with in 3days after collected in lab. The age of each block shall be 28 days.
Class: Two classes i.e. compressive strengths are specified. Class 25 has an average compressive strength of at least 25 MPa. Research has shown that the structural performance of the pavement is dependent on the degree of interlock, which spreads the load and is virtually independent of the strength of paving blocks,
