The Effect of Capping Condition on the Compressive Strength of Concrete Hollow Blocks [PDF]
مجلة جامعة النجاح للأبحاث العلوم الطبيعية, 2003 One of the quality control tests done on the concrete hollow blocks is the compressive strength. In order to simulate in situ strength of the concrete blocks, capping technique was used in order to achieve smooth perpendicular surface for compressive ...

Damage-cluster distributions and size effect on strength in compressive failure [PDF]
, 2012 We investigate compressive failure of heterogeneous materials on the basis of a continuous progressive damage model. The model explicitely accounts for tensile and shear local damage and reproduces the main features of compressive failure of brittle ...
