This paper examined the properties of high-strength pervious concrete to investigate the applicability to highways. The properties included porosity, compressive strength, and flexural strength. The high-strength pervious concrete were produced using ordinary Portland cement, silica fume premixed cement, and geopolymer as binding materials. Consequently, the experiment confirmed that the relationship between the compressive strength and flexural strength of pervious concrete using high-strength binding materials (compressive strength of 150 N/mm² or higher) such as silica fume premixed cement (water-cement ratio = 0.15) and geopolymer (solution-powder ratio = 0.5). In addition, it confirmed that their porosity can be approximated by an exponential function, similar to that of pervious concrete using ordinary Portland cement as a binding material. Furthermore, it was observed that pervious concrete using silica fume premixed cement (water-cement ratio = 0.15) as a binder could achieve a compressive strength of 22.5 N/mm² and a flexural strength of 4.5N/mm² up to 20% porosity, emphasizing water permeability. In addition, it was established that pervious concrete using geopolymer as a binder could achieve a compressive strength of 22.5 N/mm² in the high-porosity range of 20-25% and partially meet the flexural strength requirement of 4.5 N/mm², also in the region emphasizing water permeability. These results demonstrate the potential of high-strength pervious concrete for use in highways.

“…There is an abundance of published literature on the characteristics, mechanical properties and durability aspects of PC since this type of concrete has been developed some time ago. For example, there is available literature that addresses plain PC [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] as well as PC that incorporates supplementary cementitious materials [18][19][20][21][22]. However, research on PC that contains RCA as partial or full replacement of NA remains relatively scarce, especially in combination with fibers that are capable of compensating for the inferior properties of the recycled aggregate.…”

This study considers 12 pervious concrete mixes incorporating 100% recycled coarse aggregate from old concrete demolition waste and containing various amounts of natural fine aggregate and date palm leaves fibers. First, the properties of the recycled aggregate in terms of their particle size distribution, abrasion resistance, crushing values, specific gravity and water absorption are obtained. Next, the pervious concrete density, compressive strength, tensile strength, permeability and porosity are determined by experimental testing following the relevant standards. The results are analyzed and compared to determine the influence of using recycled coarse aggregate in the mixtures and the impact of the amount of natural sand and volume fraction of the fibers on the mechanical properties, permeability and porosity of the concrete. Findings of the study showed that the use of recycled coarse aggregate in pervious concrete without fine aggregate reduced the compressive strength by 36% and tensile strength by 57%. Replacing 11.7% of the recycled coarse aggregate with natural sand and adding date palm leaves fibers in an amount equivalent to 0.64% volumetric content to such concrete helped increase the compressive strength by 16.2% and tensile strength by 3.2% above the corresponding strengths of the control mix. There is a clear relationship between permeability and porosity due to their correlation with the density of pervious concrete, and the effect of porosity on tensile strength is more influential than it is on the compressive strength. An equation that can predict the tensile strength of pervious concrete from the compressive strength is proposed, as a function of the natural fine aggregate fraction of the coarse aggregate and volumetric content of natural fibers. Results of the research confirm the feasibility of using recycled aggregate in pervious concrete mixes and the positive impact of natural fibers on the mechanical properties.

It is unknown whether Ferronickel slag (FNS)-ordinary Portland cement (OPC)-based pervious concrete (FOPC) is feasible. To this end, a feasibility study was conducted on FOPC. Firstly, a detailed microscopic examination of the FNS powder was conducted, encompassing analyses of its particle size distribution, SEM, EDS, and chemical composition. These analyses aimed to establish the suitability of a composite of FNS and OPC as a composite cementitious material. Subsequent experimentation focused on evaluating the compressive strength of the composite paste material with varying mixed proportions, revealing a slight reduction in strength as the FNS substitution rate increased. Furthermore, the study designed eighteen different mix proportions of FOPC to investigate the key physical properties, including porosity, density, compressive strength, and the coefficient of permeability. Findings indicated that increases in the cementitious material proportion correlate with enhanced concrete strength, where the ratio of cementitious to aggregate increased by 6.7% and 16.5%, and the strength of FOPC increased by 10–13% and 30–50%, respectively. Conversely, a rise in the FNS substitution rate led to a reduction in compressive strength across different mix ratios. Additionally, the ratio of paste material to aggregate was found to significantly influence the permeability coefficient. These comprehensive performance evaluations suggest that incorporating FNS into OPC for pervious concrete applications is a feasible approach, offering valuable insights for the promotion of waste reuse and the advancement of energy conservation and emissions reduction efforts.
