A brief review on the fabrication and mechanical behavior of functionally graded concrete materials

Abstract

Functionally graded concrete materials (FGCs) are new concrete composites whose functions and properties change with the spatial position. In this paper, the research status on the fabrication and mechanical behavior of FGCs was briefly reviewed, and the next work is also summarized.

Flexural Characteristics of Functionally Layered Fiber-Reinforced Cementitious Composite with Polyvinyl Alcohol Fibers

“…These kinds of composite materials have undergone a series of materials and emerging structural developments after the concept introduction for industrial applications such as in the aerospace, automotive, and biomedical fields [16][17][18]. Some studies [19][20][21][22][23] have applied the concept of a functional gradient to the field of cementitious structures in order to maximize the rational application of the mechanical properties while reducing costs and the emission of greenhouse gases. Torelli and Lees [24] proposed an original fresh-on-fresh casting method to generate functionally layered concrete sections composed of an external U-shaped durability layer of low porosity concrete and a rectangular lightweight bulk core section, which aimed at minimizing the use of cement and to reduce the self-weight of precast concrete beams.…”
