It has become common use to replace the diametrical tensile split test on cores taken out of concrete blocks by a split test carried out on the block itself generally at a distance of one of the ends equal to a half of the height of the block The split tensile strength is expressed using the classical relation established for disks σ br =2P/πHl whereP is the fracture load H the height of
