A set of 18 concrete and six mortar mixes is described, with cube strengths at 28 days of 74 to 117 MPa and electrodynamic E values of 47 to 55 GPa (37 to 42 GPa for the mortar). Very limited potential for increased E is seen after 28 days and comparative detrimental effects are noted due to air-dry
The size effect of concrete strength has been analysed by statistical theories of brittle materials in this paper. On the basis of available theories and experiments, normal distribution was used in preference to any other. The use of Weibull's theory in a non-uniformly tensile stress state has been
