The performance of a concrete road slab is critically affected by its ability to withstand the tensile stresses imposed upon it caused by temperature movements and loading. The quality of concrete used in road slabs is therefore most logically specified in terms of its tensile strength. The cylinder-splitting test, which gives an indirect measure of tensile strength, is likely to be used in a future revision of the Department of the Environment's 'Specification for road and bridge works'. This report describes studies that have been made to investigate the effect of different materials on the indirect-tensile strength and on its relation with the cube-crushing strengths. It is shown how the relation between compressive and indirect-tensile strength is dependent on aggregate type and how the relation is affected by entrained air and different sources of cement. Data presented in the report should assist in the design of mixes on the basis of indirect-tensile strength for both plain and air-entrained concretes. /TRRL/
