High performance concrete

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.

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 main objective of this paper is to categorize the available literature (analytical/experimental). The discussion remains descriptive, and the reader is recommended to consult the cited references for specifics on parameters and mathematical models. Three phases were adopted to conduct this literature review: (a) conducting the review, (b) conducting the analysis, and (c) writing up the review.

The main focus of this research is the composite comparison of steel fiber, polypropylene fiber and basalt fiber as it is a new category of hybrid fiber reinforcement in high performance high volume flyash concrete. Also many other researchers have studied incorporating individual fibers in high volume flyash concrete to improve the mechanical properties.
