Roller compacted concrete (RCC) is a material with no slumps and is made from the same raw materials as conventional concrete. The roller compacted dam method, the high paste technique, the corps of engineers method, and the maximum density method are all ways of designing RCC. The evolution of RCC has resulted in a substantial change in construction projects, most notably in dams, because of the sluggish pace of conventional placement, consolidation, and compacting. The construction process was accelerated by incorporating RCC into dams, resulting in a shorter construction period. Research shows that the dams that used RCC had completed one to two years sooner than the dams that used regular concrete (Bagheri and Ghaemian's, 2004). The application of RCC has risen significantly during the past several decades, particularly for pavement applications. It has a lower construction cost than asphalt and may be completed fast. It is extensively used in areas/roads that transport big goods at moderate speeds. RCC is increasingly being used in metropolitan areas, particularly on roadways and streets. RCC has shown great interest in asphalt roads in terms of durability, compressive strength, prolonged service life, and lower maintenance costs. Fibre addition is frequently favored in RCC, just as in traditional concrete. Fiber inclusion contributes to the mechanical qualities of RCC as well as its long-term sustainability. Within the focus of this research, RCC is reviewed based on four factors: environmental effect, cost, fiber addition, and country-specific RCC use. This study is unusual in this sense and provides researchers with valuable information

“…At present, the demolition of waste buildings in the brick structure and masonry structure accounted for a considerable proportion, research shows that [5][6][7] the main components of construction solid waste for waste concrete and waste brick, of which waste concrete accounted for 41%, waste bricks accounted for up to 40% or more; and in small and mediumsized cities and rural areas, waste bricks accounted for a higher proportion of the even reached more than 70%. Therefore, in the face of the problem of solid waste utilization in construction, not only to deal with a large number of waste concrete, but also to solve a considerable number of waste bricks.…”

Aiming at the background of the application of fracture mechanics in fiber recycled concrete as well as the shortcomings of the current research, the relevant results and progress are summarized from three aspects, namely, the basic theory of fracture mechanics of fiber recycled concrete and the research progress of the fracture properties of fiber recycled concrete as well as the testing methods of the fracture of fiber recycled concrete, respectively. The development history of the application of fracture mechanics in concrete is described, three fracture forms, fracture process zones and three softening curve models of concrete are introduced, and it is proposed to combine the bilinear softening curve and the virtual crack zone model to construct the ontological relationship of the whole process of concrete cracking. The current research status of recycled brick aggregate concrete and polypropylene coarse fiber concrete is introduced. The incorporation of recycled brick aggregate adversely affects the workability, basic mechanical properties and fracture properties of concrete. The reinforcing effect of polypropylene fibers on concrete can effectively improve the adverse effects of brick aggregate on concrete, which opens up the research prospect of green concrete and has high research value. The applications of three-point bending test, four-point bending test and DIC technique in the study of concrete fracture characteristics are introduced.

“…Reusing and recycling waste materials is seen as the most environmentally friendly solution to the disposal problem. Therefore, a new approach to lightweight concrete production resembles the utilization of lightweight materials (agriculture and building waste materials and cork) as a replacement for aggregate (coarse or fine) (Selman and Abbas, 2022; Abdullah et al, 2021). lightweight materials can be utilized as a whole or partial substitute to aggregate; hence, it is a new approach to producing lightweight concrete.…”

This study aims to evaluate experimentally the mechanical characteristics of Self-Compacting Concrete (SCC) comprising expanded polystyrene beads (EPS) to produce flowable lightweight concrete reinforced with steel fibers. In this paper, the effect of steel fibers and EPS content on the fresh and hardened mechanical properties of SCC specimens, using two percentages for Polystyrene aggregate replacement (25% and 50%) and three values for volume fraction of steel fiber content (0%, 0.75%, and 1.5%), were examined. Fresh mixture properties were determined using slump flow, L-box, and V-funnel tests. Mechanical properties for hardened samples were obtained using standard specimens for compressive strength, density, split, and flexural strength. The study showed that EPS content has no adverse effect on the rheological features of the SCC. However, workability falls below specification limits when adding steel fibers to SCC. Results revealed that using 25% of EPS content resulted in lightweight structural concrete, while lightweight moderate-strength concrete was produced using 50% of EPS content. Furthermore, the study has shown that the split and flexural tensile strength were reduced substantially by 53% and 60% due to EPS addition. However, adding steel fibers remarkably improved the indirect tensile strength and Modulus of rupture by 46% and 80%, respectively. The mode of failure of the concrete specimens containing EPS beads and steel fibers did not show brittle failure behavior generally encountered in normal-weight concrete, indicating a more ductile behavior.
