“…This trend has been observed in a similar study, which used fly ash as a subsidiary cementitious material for recycled aggregate-based pervious concrete [15]. Additionally, the study of Tripathi, Hussain, and Madhav [16] emphasized the possible influence of compaction on compressive strength values of concrete. It should also be noted that permeability and compressive strength displayed an inverse relationship, which suggests an optimal replacement ratio of admixtures for the ideal mix design.…”

The need to improve traditional concrete practices and the existing waste problem in the Philippines has opened an opportunity for by-products, such as scrap rubber tires and fly ash, as sustainable alternative materials in pervious concrete. This study investigates the effect of shredded rubber tires and fly ash content on the strength and permeability of pervious concrete. A total of 15 mix designs, with varying replacement ratios based on weight, were produced and tested for compressive strength, split tensile strength, and infiltration rate. In particular, the percentage replacements tested in the study were 0%, 10%, 20%, 30%, and 40% for the shredded rubber tires, while fly ash ratios were set at 0%, 10%, and 20%. Two-way ANOVA test and desirability function statistical analyses were conducted to determine the optimal replacement of shredded rubber tires and fly ash. Results showed that the addition of shredded rubber tires produced a decreasing trend, while increasing the fly ash content exhibited an increasing trend, both on the compressive strength and split tensile strengths. On the other hand, the infiltration rate increased with the addition of rubber aggregates. The research findings also indicated that using up to 10% shredded rubber tires, with 10-20% fly ash, yields a more desirable pervious concrete than the conventional mix.

“…Test procedures from IS 4031 (Parts 4 and 5): 1988 [20][21] are adapted for confirmation of the basic properties of binder. Earlier studies show that the use of coarse aggregate and binder in the ratio 4:1 gives good compressive strength in comparison to other ratios [22]. The water cement ratio of 0.40 was adapted and maintained constant throughout the study.…”

This study tends to use polyacrylamide (PAM) as a potential cement replacer for the enhancement of pervious concrete properties. The study considers four different replacement percentages and compares them with a zero-percentage replacement mix. The properties that were analysed in the fresh state before hardening include slump value, flow percentage, and fresh density of the mix. The analysis also includes further hardened properties such as water absorption, density, infiltration capacity, porosity, and abrasion resistance In addition, compressive strength under two different curing conditions, namely water curing and air curing. is analysed. Microstructural analysis is further performed using FTIR, XRD, and SEM/EDAX to confirm the experimental analysis. The results indicate a 12% increase in the maximum compressive strength in the mix with 0.5% replacement compared to the reference mix. Strength analysis also reveals that the polymer acts as a retarder. Using PAM to replace cement reduces water absorption, density, porosity, and infiltration capacity. In addition, the water treatment ability of various pervious concrete specimens is also analysed in terms of Total Suspended Solids (TSS), Chemical Oxygen Demand (COD). Total Phosphates (TP), Total Nitrogen (TN), Biochemical Oxygen Demand (BOD) and Total Organic Carbon (TOC). Results show that TP removal was as high as 82.5% in a mix with 2% replacement. Therefore, PAM can be regarded as a potential partial cement replacer in pervious concrete.

Pakistan is facing adverse environmental issues peculiarly in major cities. The condition gets worst during monsoon period when the whole city faces the urban flooding due to stagnation of storm water on all major streets and areas. The main reason is the lack of infra-structure to mitigate the crisis which is faced by the country during whole rainfall season. The introduction of Pervious Concrete in major pavement infra-structure can easily limit the problems of sump of rain water. As a part of road infrastructure, the upper layer of pavement can be pervious, making runoff water to move to sub-base. This paper offers the exploratory research to ascertain the compressive strengths and infiltration rate of different samples of Porous Concrete following the American Concrete Institute guidelines. The experiments were done with varying the properties of Pervious Concrete. The effects which were considered are curing time, mix proportion, percentage quantity of fine aggregate, ratio of water to cement and varying coarse aggregate size. The mix design ratio considered were 1:4, 1:5 and 1:6. For further experiment of infiltration rate, the custom slab was formed with dimensions 2’x1’x4” and was tested for all the desired ratios. For the purpose of cost comparison, a fixed size on land is kept as standard. The cost is compared for construction on the land, using three different materials: Pervious concrete, Traditional concrete and Asphalt premix.It was showed that the Traditional concrete is cheaper than the Pervious and Asphalt layer but Pervious concrete is also economical than Asphalt layer.
