WebAug 10, 2024 · The shear strength and dilatancy of typical uncemented calcareous sand from the South China Sea are investigated by soil lab tests. According to drained triaxial tests at various relative densities and confining stresses, it is found that the constant volume friction angle is approximated as 39° and the traditional Bolton’s equations can be … WebThe macroscopic analysis of the composition of the mortars suggests a lime-based binder and silico-calcareous aggregates of fine-medium size. Regarding the granulometry, with the exception of sample NO6, which had aggregates with an average diametre of above 3 mm (and can therefore be classified as concrete type), the mortars are mainly ...
