Abstract
Fibre-reinforced concrete is an emerging trend that delivers new materials with high quality for construction. Basalt fibre, an mineral fibre, has high potential to be used for reinforcing concrete, but there has been little research conducted into using this fibre for concrete reinforcement worldwide and no research work on this fibre reinforced concrete has been published in Vietnam. Therefore, researching into Baslat fibre reinforced concrete to establish fundamental understandings and material mixture recommendations is considered to be scientifically significant and practically worthwhile, especially for the climate and construction conditions in Vietnam. With the use of theoretical and experimental research methods, a procedure for designing the composition of Basalt fibre reinforced concrete was achieved and presented in this paper.

Abstract
Reinforcing soil for solving the geotechnical problems is a very useful and economical technique. Soil as a grainy environment has a very good resistance under pressure and when it is cut, but is not that much resistant when being pulled. Being reinforced due to increase of the friction, it will be more resistant when being cut. I this survey we leveled our focus on the analysis of modeling loose sand and using image process for measuring the displacement Vectors and also, investigating the effect of different factors such as reinforced type and layer on the soil failure mechanics and we compared consequences with unreinforced status of the soil. The results convey this very message that the surfaces of the soil which were failed and also the depth of mentioned surfaces in reinforced model compared to unreinforced one increase and cover more loading capacity.
Keywords: Reinforced soil, displacement vectors, soil mechanics, image processing.
