Experimental Study on the Mechanical Properties of Reinforced Pervious Concrete

Abstract

Pervious concrete (PC) has gained popularity as an environmentally friendly solution for mitigating the urban heat island effect and promoting sustainable construction. However, its lower compressive strength, attributed to its higher porosity required for permeability, poses challenges for withstanding heavy vehicle loads on pavements. Our study aims to improve the flexural strength of regular PC by adding advanced reinforcing materials like steel wire mesh or glass fiber mesh. This results in reinforced pervious concrete, referred to as RPC, which offers enhanced strength and durability. The primary objective of our research is to investigate the mechanical behavior of RPC, with a specific emphasis on essential design parameters such as PC elastic modulus, modulus of rupture, and stress–strain characteristics under both single and repeated loading conditions. Our findings reveal that the influence of repeated loading on the compressive strength and elastic modulus of PC pavement is negligible, as there are no significant differences observed between the two loading protocols. Notably, our statistical analysis indicates that the PC strength (fc′) averages around 15 MPa. Moreover, empirical formulas for the elastic modulus (Ec = 3072fc′) and modulus of rupture (fr = 0.86fc′) are derived from our research. Furthermore, our study establishes that the stress–strain behavior of PC closely aligns with the general concrete model proposed by a previous scholar, providing valuable insights into the material’s structural performance. These findings contribute to a better understanding of RPC’s mechanical properties and offer potential solutions for improving its suitability for heavier vehicular loads.

Corrosion of Steel Rebars in Construction Materials with Reinforced Pervious Concrete

“…Table 2 shows the results obtained for two tests for each aggregate size. These were in accordance with other published works that indicate that compression strength is more related to voids and the binding material used [1,43,44]. The compressive strength values show that all the specimens were within the range of 65-82 kg/cm 2 , between M5-and M10-grade concrete.…”

Research on Statistical Characteristics and Prediction Methods of Ferronickel Slag Pervious Concrete Performance with Different Sizes of Aggregate and Mixtures

“…Meanwhile, Lee et al [2] scrutinized the characteristics of pervious concrete, both of high strength and of conventional strength, when augmented with either steel or glass fibers, employing fifteen distinct mixes of these materials. Further, Lee et al [3,4] broadened their research scope to examine the influence of advanced reinforcement materials, such as steel wire and glass fiber meshes, on the flexural strength of standard pervious concrete. They concentrated on key design variables, including the elastic modulus, modulus of rupture, and stress-strain behavior under various loading conditions.…”

Study on the Performance Evolution of Hydraulic Concrete under the Alternating Action of Freeze–Thaw and Abrasion

“…Currently, the majority of the existing research is devoted to the influence of a single factor on the performance of hydraulic concrete, while research under the action of multiple factors is relatively scarce [12]. For example, the addition of an appropriate amount of fibre into pervious concrete can enhance its resistance to wear while enhancing permeability by modifying the structural framework of concrete, thereby reducing the erosion damage inflicted by high-speed water flow [13][14][15]. The coupling of freeze-thaw cycles and adverse effects on hydraulic structures is the main focus of this type of multi-factor study [16][17][18][19][20][21].…”
