TL;DR: In this article, the use of recycled aggregates (RAs) for making pervious geopolymer concrete (PGC) was studied, and the results indicated that both RC and RB can be used as recycled coarse aggregates for making PGC with acceptable properties.

TL;DR: In this article, the properties of pervious concrete made of high-calcium fly ash geopolymer binder were evaluated and the relationship of the density-void content, compressive strength-density, and compressive-strength void content of the PGCs were derived and found to be similar to those of conventional concrete.

TL;DR: In this paper, rice husk ash (RHA) was used in order to strengthen pozzolanic cement paste and the effect of 0, 2, 4, 6, 8, 10% and 12% weight percentages as a cement replacement in concrete mixtures on the mechanical properties was studied.

TL;DR: In this paper, the properties of pervious concretes containing two types of recycled aggregates (RBA and RCA) were studied and the improvements in strength and abrasion resistance were achieved as a result of better bonding between recycled aggregate and cement paste due to increased surface porosity and roughness of recycled aggregate.

TL;DR: In this article, a computerized falling head permeameter system was used to measure hydraulic conductivity of pervious concrete from samples taken from three different field-placed slabs with known porosity.
Abstract: A computerized falling head permeameter system was used to measure hydraulic conductivity of pervious concrete from samples taken from three different field-placed slabs with known porosities Important differences between samples were found, and these follow the same trend as differences in porosity The relationship between porosity and hydraulic conductivity is suggested as a tool for designing pervious concrete pavements as a stormwater pollution best management practice A quantitative relationship between porosity and hydraulic conductivity was established based on the Carman-Kozeny equation for the samples tested Samples with porosities less than 15% presented limited hydraulic conductivity Important considerations on the measurement of hydraulic conductivity of pervious concrete samples are discussed, and the Ergun equation is used to explore the flow regime inside pervious concrete samples
