To enhance load-bearing capacity and prevent structural damage, reinforced concrete elements are often strengthened with additional layers of material. This study investigates the bonding performance between Textile Reinforced Concrete (TRC) and reinforced concrete slabs through four-point bending tests.

The results of ultrasonic wave propagation experiments indicated that the presence of steel fibers at a 2% content increased the time of wave propagation. On the other hand, curing conditions, specimen maintenance time, and transmission path distance affected the ultrasonic wave propagation time in high-strength concrete.

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.

Steel fiber reinforced concrete (SFRC) is a multiple-composite material developed during the early 1970s. In SFRC, short steel fibers are randomly distributed in concrete. Steel fibers can prevent the development of micro-cracks inside the concrete and reduce the expansion and development of the macro-cracks, thus enhance mechanical performance of SFRC. However, there is lack of studies on the influence of flowability of fresh SFRC on the steel fiber distribution patterns and mechanical properties of hardened SFRC.

Portland cement concrete (PCC) / asphalt concrete (AC) bonded components are seen in both conventional pavement structures as well as overlays. Due to the environmental and traffic loads, cracks occur at the interface of the PCC and AC layers and finally, may propagate through the interface or one of the layers.
