This paper uses the discrete element method to simulate a soft grain that can deformed without rupturing. This soft grain is composed of rigid primary particles with a cohesive contact law between them. The results showed that rigid primary particles within the deformable grain can move and rearrange in response to vertical compression.

In Vietnam, there is not enough sand from the river for the construction operation, and it is necessary to find other resources to replace it. Marine sand was distributed in large areasin the coastal area of Vietnam and was not used for rural roads. This paper presents experimental results on the workability and compressive strength of concrete which was made from Nghe An and Ha Tinh marine sand.

The purpose of this research is to analyse the available design equations and present the applicability of these equations for their use in the design of beams made of higher concrete strengths. In the present program concrete having compressive strength of 50MPa or more is considered as high strength concrete. Analytical investigation on HSC beams is made under four different aspects namely flexure, ductility, deflection and shear.
