โœฆ Synopsis

The effects of the maximum void size ann aggregate shape and roughness on the flexural strength of high strength mortar were investigated. Substantial reductions in the maximum void size and air content of quartz aggregate mortars resulted in flexural strength increases. These increases in flexural strength were somewhat lower than predicted by Griffith's theory, thus su~esCing that the maximum void size did not act as the critical flaw controlling the flexural strength.

Factors relating to the cement-aggregate bonn, including auregate shape ann roughness, appeared to affect the flexural strength more than the maximum void size.

The effect of three fillers (ground limestone, dolomite and basalt) on the strength of cement mortars was studied on 1:2.75 mixes having a w/c ratio of 0.70. The filler content ranged from i0 to 40% of the cement weight and their fineness (specific surface) from 1,150 to 11,200 sq.cm per g. Results

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
