This paper presents the mechanical behavior of functionally-graded concrete (FGC) beam under flexural bending. The FGC beam was made of conventional concrete of strength class 30MPa with a thickness of 45mm and high performance glass fiber reinforced concrete (HPGFRC) of strength class 60MPa with thickness of 15mm.

This article presents the experimental results on the flexural behavior of reinforced concrete (RC) beams strengthened with textile-reinforced concrete (TRC). Four RC beams were made of B22.5 grade concrete, and the TRC strengthening layer utilized Sigratex Grid 350 textile, with fine-grained concrete Sikagrout 214-11 serving as the binder.

Study on the punching shear capacity of reinforced concrete and prestressed concrete flat slabs with the concrete grade is not greater than B60, no shear stirrup, no slab openings, no consideration of influence of moment at column-slab connections, columns with circle or rectangular section only.
