To check the applicability of the Griffith theory to portland cement systems which are neither elastic nor homogeneous, specimens of hardened cement paste, mortar and concrete made with normal and lightweight aggregates, and with notches of varying lengths were tested in flexure and in tension. While the paste specimens were notch- sensitive, mortar and concrete strengths were independent of notch length. It appears that for mortar and concrete the direct application of Griffith criteria is not valid up to a certain length of cracks. This critical length depends on the size, volume, and type of aggregate.
