The behaviour of large size concrete specimens (250 × 250 500 mm) in uniaxial tension has been studied. complete tensile stress–strain response the was acquired through a limited experimental programme. programme comprised testing three different mix categories. A relationship between and nominal compressive strengths established. Accordingly, strength can be predicted by expression [Formula: see text], where f′ t c are respectively. In comparison with expressions for small (150 150 300 mm), this predicts lower mm). addition, axial stress–crack width curves, fracture energy brittleness concretes also obtained based on stress–deformation curves. It found that both dependent maximum aggregate concrete.
