摘要：

In this paper, the influence of geometrical and physical parameters (size of the sand particle, thickness of the interface layer and ratios of the modulus of elasticity) on stress distributions in a mortar is studied. It is found that a weak or soft interface layer in the mortar will greatly reduce the strength of the concrete; if the modulus of the interface layer approaches to that of the cement paste and the modulus of the sand particle (or aggregate) is 4-10 times as large as that of the cement paste, the concrete will possess a much higher strength and thus has a better property.
