“…This difference affects the mechanical properties of PC. Regarding the flexural tensile strength results, these follow the same tendency observed in the compressive strength results as expected [45]. In this study, the flexural tensile strength is on average 40% of the compressive strength agreeing with the results found in the literature review [41].…”

The aim of this study was to propose a correlation for the hydraulic parameters of pervious concrete (PC). Thus, three aggregates from civil construction waste and one basalt aggregate (reference) were used to produce PC. The ratio c/a (cement: aggregate) 1:3.26 and a w/c ratio of 0.34 were used in all mixtures. Compressive and flexure tensile strength tests were performed to mechanically characterize the mixtures produced, whereas porosity and constant head permeability tests were also carried out to assess the material hydraulic properties.Firstly, the experimental results were compared with the requirements established in international guidelines (ACI 522R-10, NBR 16416(2015) and VTT-R-080225-13). The results complied with the guidelines indicating it is feasible to produce pervious concretes with the sustainable aggregates used in the study in low structural applications such as walkways. On the other hand, a correlation between permeability and porosity was proposed based on Darcy’s and Bernoulli’s laws. The proposed equation, obtained by means of a non-linear regression, is an exponential equation that characterizes the hydraulic efficiency of the internal channels of the material considering the pores interconnection. The correlation between porosity and permeability was finally validated using results from the literature showing the same trend found in laboratory, and therefore it was demonstrated that the proposed correlation in an efficient tool to predict the hydraulic efficiency of pervious concrete.

“…This was attributed to the wide particle size distribution that increases the probability of retention, and the cohesive nature of clay causing more surface interactions and particle adhesion. Nguyen et al (2017) found that silty clay and sand caused the most rapid clogging. The work of Coughlin et al (2012) concluded that clay caused approximately ten times more clogging per unit mass than sand.…”

“…Some studies have applied sediments for a set number of cycles while others have proceeded until the sample is fully clogged. Some research has included a cleaning cycle to simulate periodic maintenance (Haselbach, 2010;Deo et al, 2010;Patel et al, 2012;Mata and Leming, 2012;Coughlin et al, 2012;Schaefer et al, 2011;Tong, 2011 andNguyen et al, 2017). Therefore, the variable findings are due to researchers using a range of different test methodologies.…”

“…Monita Olivia et al [1] also used ground cockle shell as SCMs, they found that the compressive strength has been an optimum value by 4% of replacement, while the tensile strength and flexion have been shown better results with the seashell concrete. Dang Hanh Nguyen et al [9] found that the crushed seashells can be used as a replacement in the previous concrete composition, for low-volume roads, they showed that an acceptable durability of pervious concrete with and without crushed shells for the application of low traffic load. According to Monita Olivia et al [10], the substitute of the Portland cement with the ground cockle shell and clam shell influenced in physical and mechanical properties of the concrete, the OPC cockle concrete showed lower setting time, density and tensile strength than the OPC concrete.…”

This paper studies the use of cockle shell as supplementary cementitious materials SCMs as substitute for cement. The cockle shells generally have a high CaO content which can alter the behavior and the properties of mortars and concrete. Cockle shell is used with weight ratios of 5, 10, 15 and 20% to formulate a mortar with cockle shell and a control mortar CM with 0% of cockle shell. The properties in the fresh state, the mechanical strength and the weight loss test as well as the depth of penetration of each mixture were carried out through the conducted experiments. Consistency and density of fresh mortars were determined, the results obtained showed that cockle shell have a significant influence on the properties of mortars in the fresh state. The different results of hardened mortars show that the introduction of cockle shell tends to accelerate the development kinetics of strength at the young age but its ratio cannot be above of 5%. Mortar with 10% presented the lower depth penetration, the loss weight increased proportionally with the increasing of cockle shell amount.
