“…There was a strong relationship between the porositydensity-strength properties and it says as porosity increases, the density decreases, which lowers the strength of concrete. In fact, it was also observed that the increase in porosity would definitely lead to an increase in the permeability coefficient as well, and subsequently, decreases the density [31].…”

“…Otherwise, the superfluous cement paste would significantly decrease the porosity and thereby lower the permeability of PC. The different types of aggregate gradation, water-to-cement (w/c) and cement-to-aggregate, and compaction techniques with variations in efforts play an essential role in providing an optimum balance in the mixture designing of PC mixtures [31]. Broader application of PC could be achieved through increased ravelling resistance and enhanced durability performance [2 &12] which is possible through proper selection of materials and mix proportioning.…”

“…The size of aggregates plays a crucial role in the porosity, density, and permeability of PC mixes. The larger size of aggregates induces higher porosity and more interconnected pores within the PC matrix, despite being well graded in nature [31]. The effect of different gradations at varying w/c ratio on the porosity and permeability of PC mixtures cured till 28 days is shown in Figure 7 Yu et al [58] used 2D/3D CT images to investigate the relationship between pores characteristics and permeability.…”

Pervious concrete a sustainable solution with limited fines or no fines and interconnected voids, has many environmental benefits, such as reducing the stormwater run-off, improving the groundwater table, reducing water pollution, and mitigating urban heat island. Many research works have been done in Pervious Concrete (PC) by varying different parameters such as, types of aggregate, aggregate gradation, water-to-cement (w/c) ratio, cement-to-aggregate ratio, geopolymer binder, ultra-high strength Matrix and compaction techniques. All these parameters have direct influences on the strength, porosity, permeability, hydraulic efficiency and durability characteristics of PC. The main aim of this paper is to review the recent work carried out in pervious concrete under six different categories (i) Effect of binders, coarse aggregate, admixtures and fibers used in PC (ii) Mechanical and durability properties (iii) pore structure characteristics (iv) Study on Clogging Effect (v) Role of PC in the water purification process and (vi) Numerical model in PC.

“…At present, PC is widely used in parks, sidewalks, light vehicle roads, and squares [14][15][16]. Generally speaking, the permeability and compressive strength of PC can meet the engineering requirements [17][18][19][20]. However, when PC is used as road surface or base layer, it will often be subjected to the repeated vehicle loads, which requires that PC not only has sufficient strength but also has certain deformability to resist fatigue [21].…”

The waste crumb rubber (WCR) and silica fume (SF), as industrial waste and byproduct, are widely used as additives in road construction materials, which can not only realize waste utilization and protect the environment but also reduce the consumption of building material resources. At present, most of the research has focused on the properties of concrete modified only by WCR or SF; there are few studies concentrated on composite modified concrete by the two, especially the study on pervious concrete (PC). This article aims to study the mechanical strength, deformability, and freeze-thaw (F-T) resistance of waste crumb rubber/silica fume composite modified pervious concrete (RSFPC). The RSFPC and control specimens were manufactured in the lab. The experiments of compressive strength, flexural strength, flexural failure strain, flexural elastic modulus, and F-T cycles were conducted. In addition, the properties of RSFPC were compared with WCR and SF single modification PC. The results indicate that the composite modification of WCR and SF can give full play to the advantages of the two materials so that the strength property and elastic modulus of PC will not be decreased and the F-T resistance and deformability can be greatly improved. Compared to a single modification group by WCR or SF, RSFPC has a more balanced and comprehensive performance, which will greatly expand the application of PC.

“…To enhance the pore ratio of pervious concrete, natural and artificial fibers can be used despite the reduction of strength and freeze-thaw resistance [10]. Pervious concrete has widely been used for pavements, vegetation concrete beds, and noise absorbing concrete [11,12]. Its ranges of porosity and compressive strength are typically 15-25% and 22-39 MPa, respectively [12].…”

The use of lightweight concrete has continuously increased because it has a primary benefit of reducing dead load in a concrete infrastructure. Various properties of lightweight concrete, such as compressive strength, elastic modulus, sound absorption performance, and thermal insulation, are highly related to its pore characteristics. Consequently, the identification of the characteristics of its pores is an important task. This study performs a comparative analysis for characterizing the pores in cementitious materials using three different testing methods: a water absorption test, microscopic image processing, and X-ray computed tomography (X-ray CT) analysis. For all 12 porous cementitious materials, conventional water absorption test was conducted to obtain their water permeable porosities. Using the microscopic image processing method, various characteristics of pores were identified in terms of the 2D pore ratio (i.e., ratio of pore area to total surface area), the pore size, and the number of pores in the cross-sectional area. The 3D tomographic image-based X-ray CT analysis was conducted for the selected samples to show the 3D pore ratio (i.e., ratio of pore volume to total volume), the pore size, the spatial distribution of pores along the height direction of specimen, and open and closed pores. Based on the experimental results, the relationships of oven-dried density with these porosities were identified. Research findings revealed that the complementary use of these testing methods is beneficial for analyzing the characteristics of pores in cementitious materials.
