Flooding is one of the climatic change consequences that has become a dangerous threat to many coastal cities. Pervious concrete is considered a solution to decrease rainwater runoff and mitigate flood effects, as it allows water to percolate through the ground and prevent possible damage. Using waste products as aggregates in pervious concrete not only exploits waste materials and makes it valuable but also reduces the amount of this waste ending in the landfill or harming the environment, and it decreases the demand for natural resources. Infiltration rate test and compressive strength tests were conducted to investigate the effect of using waste plastic and/or recycled rubber as concrete coarse aggregates with different ratios (5%, 10%, 15%, 20%, and 25%) on the pervious concrete. The results showed that increasing the waste materials in concrete decreased the compressive strength for all ratios while increased the infiltration rate values.

This paper presents the experimental results on the effect of metakaolin (MK) as a replacement of cement in pervious cement concrete based on compressive strength, void ratio and permeability test. Metakaolin was used to replace Portland Cement Composite (PCC) in pervious concrete by 10% (by wt.). The results show that pervious concrete sample containing 10% metakaolin with 1% superplasticizer exhibited 4 times higher compressive strength at 7 days when compared to normal cement concrete. In addition, the continuous voids of 10%MK concrete sample was found higher than PCC only, indicating the effectiveness of metakaolin in improving the interfacial bond of the binders due to micro-filler effect of metakaolin and the additional CSH gel formation. The continuous voids of pervious concrete with 10% MK is 17%, which is higher than the percentage of continuous voids in normal pervious concrete. This finding is also supported by the infiltration rate of concrete samples. Furthermore, the microstructure analysis through Backscattered Electron Imaging and X-Ray Diffraction reported denser matrix and CH reduction in polished paste samples due to 10%MK addition.

Pervious concrete technology is a special and reliable way of fulfilling increasing specifications for the climate. Pervious concrete is important in restoring groundwater, minimize erosion and converging flood water by absorbing rainwater and allowing it to seep through the land. Pervious concrete is comprised of coarse aggregate, Portland cement and chemical admixtures and is a building substance. It is somewhat different from standard concrete since there are little to no fine aggregates. The main objective of this project work is to study the densification and splitting tensile strength with the infiltration rate of pervious concrete. Also to do water quality test of rainwater after passing from 3 inches of the charcoal layer. The results concluded Compressive and splitting stability of Pervious concrete shows an extensive increment in strength when 2% of Ta titanium Dioxide is replaced by cement at the curing age of 7, 14 and 28 days. At 28 Days mean compressive and splitting tensile strength (Having Strength Enhancement Admixture) comes up to be 2104.5psi and 531.4 psi respectively which is considerable for Pervious concrete. From the infiltration rate test it can be concluded that as the percentage of gravel increases in the concrete mix, the permeability or infiltration rate increases. Infiltration rate ranges from 838.5 in/hr to 927.8 in/hr for the two concrete mixes M1 (1:0:2.5) and M2 (1:0:3) respectively. From the water quality test it can be concluded that when rainwater is passed from a 3inches layer of charcoal the PH value increase from 4.47 to 5.77 which can be used for cleaning and bathing in our houses. Hence it is recommended that 100% reduction of sand from concrete give significant mechanical strength and an increase of infiltration rate can be proposed for the roadway of parking and walking track. Also after passing rainwater from 3 inches layer it can be recommended for cleaning and Bathing Purposes.

The street curb and stormwater inlets are among the component often found on the road which serve as part of the urban stormwater drainage system. They act as a stormwater removal and discharge it into the underground drainage system. However, the current stormwater inlet practiced in Malaysia has limitations which often cause water ponding and consequently lead to road flooding. Rather than improving the performance of stormwater inlet, the flow interception and rate of stormwater removal may be enhanced by introducing a new technology called the pervious curb. It isto be made of pervious concrete which provide an ability to allow water to pass through it.This paper attempts to adapt the existingtwo pervious concrete mix design and applied it into the so-called pervious curb. Herein, a newly designed infiltration rate test was used to test the pervious concrete performance under the effect of infiltration through side surface of the concrete curb. While doing so, the infiltration rate of the pervious concrete will be investigated under varying slopes. Results showed that the infiltration rate is quite high and the rate of infiltration increases as the inclination gutter increases. Thus, it is proven that the new infiltration rate test is applicable and can be used for other similar applications. Furthermore, the test has significantly revealed that the pervious concrete has high potential in enhancing flow interception and able to reduce water ponding as a street curb.

The aim of the study is to investigate compressive strength of pervious concrete by reduction of fine aggregate from zero to 100%, additionally investigate infiltration rate of pervious concrete. Experimental study has conducted at Cecos Engineering University Peshawar. The pervious concrete samples were produced for 7 and 28 days. Compressive strength of pervious concrete indicated higher reduction of the sand reduces compressive strength and almost 50% compressive strength decreased by reduction of 100% sand from the design mix. On the other side, infiltration rate for 28 days shows direct relation above 40% reduction of sand and highest 273% of infiltration rate by reducing 100% sand from the design mix. The 90% reduction of sand from concrete give considerable compressive strength of 2150 psi and infiltration rate of 165.79 inch/hour, which can be recommended for pavements of parking and walking area.
