“…The state-of-the-art in pervious concrete focuses on reporting the mechanical and hydraulic properties of variations in the water/cement (w/c) ratio, granulometric composition, use of chemical admixtures and supplementary cementitious materials (SCMs), compaction effect, use of recycled fibers and aggregates [21], [22]. However, the composition of the mixture and fundamental criteria for concrete to meet the recommendations for application as pervious pavements still need to be explored [23].…”

This study aimed to identify the influence of replacing coarse natural aggregate with coarse recycled concrete aggregate on the thickness and volume of the cementitious paste under the variation of the water/cement ratio in the fresh and hardened properties of pervious concrete. The determined theoretical paste thickness was inefficient for pervious concrete dosage. However, it was found that the paste volume was the parameter that was best related to the mechanical and permeability properties of the studied material. Pervious concrete with natural aggregates showed higher compressive strength than concrete with recycled aggregates, although both met the regulations. All the concretes produced, except one with recycled aggregate of w/c ratio 0.25, reached the tensile strength in the minimum design bending. Pervious concrete with recycled aggregates showed more significant mass loss by abrasion and more porosity than concretes with natural aggregates. Finally, all pervious concretes presented permeability coefficients greater than the lower limit determined by the standard.

“…For instance, pervious concrete mixtures with varied dolomite aggregate types were analyzed to determine the influence of aggregate type and size on the properties of pervious concrete [15]. The properties of basalt fiber-reinforced pervious concrete (BFRPC) and carbon fiber-reinforced pervious concrete (CFRPC) with two single-sized aggregates were also compared [16]. Similarly, Malaiskiene et al [17] studied the influence of the percentage of coarse aggregates on the concrete structure with a focus on density, infiltration rate, water absorption, and compressive strength.…”

The Effect of Untreated Dura-Palm Kernel Shells as Coarse Aggregate in Lightweight Pervious Concrete for Flood Mitigation

This research aimed at ascertaining the performance of raw dura species of Palm Kernel Shells (PKS) in comparison to a different species of PKS (tenera) as a replacement for known aggregates for pervious lightweight concrete. Using limestones as the known aggregates, control pervious concrete was batched, and relevant tests were conducted. Major tests conducted on the composites concerned compressive, tensile, and flexural strength, as well as permeability, densities, and absorption. Logistic constraints on transporting the dura-PKS limited the quantity needed to ascertain the variety of replacements of the dura-PKS. With a 25% replacement known to be the most suitable ratio for related investigations, we adopted that ratio and compared to the extreme ratio of 100% dura-PKS. The tests revealed that a 100% replacement of known aggregates by the dura-PKS resulted in high porosity and permeability, although the resistances to compression, tension, and flexural loads read low for the same mixture. Instead, pervious concrete 25% of dura-PKS replacement yielded optimum water permeability rate and flexural and compressive stresses. However, the flakiness index recorded for the dura-PKS was almost half that of the tenera species and was not reflected in the mechanical properties as the results gave relatively lower strengths. The results in the case of the dura species do not differ significantly compared to the tenera-PKS in terms of strength and permeability.
