“…Concrete is the most commonly used material employed for construction purpose in the world today [1], the expensive cost of concrete constituents such as cement, fine and coarse aggregate has necessitated the need to search for alternative construction materials [1,2]. The general importance of concrete application in construction projects and civil works cannot be overemphasized.…”

“…The general importance of concrete application in construction projects and civil works cannot be overemphasized. The overwhelming demand for concrete in construction adopting normal weight aggregates (NWAs), such as gravel and sand has led to tremendous depletion in naturally occurring aggregates causing numerous damage to the environment which are irreparable [2]. As a result, the need to search for more sustainable and renewable materials has been intensified.…”

Shelter is a basic human need. Unfortunately, decent shelter for the masses; the poor have not materialized over the years. The cost of concrete materials in building and civil engineering project has been a concern to the society. These and other things led to the research on biological local materials that are dumped as waste in our environment, causing pollution and congestion as substitute materials. Therefore, this research work was carried out in respect to that and the research work was carried out to determine the use of palm kernel shell as a partial replacement for coarse aggregate in concrete taking into consideration the compressive strength and water absorption capacity. The following tests were carried out; visual test, sieve analysis, specific gravity test, slump test, water absorption test and compressive strength test. The result of water absorption and compressive strength shows that the water absorption capacity of palm kernel shell is normal compared to plain concrete and a replacement of 10% and 25% gave 4.78 N/mm 2 and 4.44 N/mm 2 compressive strengths respectively which cannot be used for light weight structure.

“…In France, a study investigated the incorporation of crushed Crepidula sp. (slipper limpet) shells into pervious concrete mixes and concluded that shell incorporation did not have an adverse effect on the concretes mechanical strength and increased porosity allowed for better water permeability, an important characteristic of pervious concretes (Nguyen et al 2013). Further studies have found similar viability of shell incorporation in various aggregate mixes (Yang et al 2010;Lertwattanaruk et al 2012;Kuo et al 2013;Nor Hazurina Othman et al 2013).…”

Mollusc aquaculture is advocated as a highly sustainable food source and may play an important role in future food security globally. With production increasing worldwide, it is timely to appraise all aspects of aquaculture when considering its expanding role as a food source. In this regard, one regularly overlooked aspect of mollusc aquaculture is waste generation: namely the production of calcareous shells. Shells from the aquaculture industry are widely regarded as a nuisance waste product, yet at the same time, calcium carbonate is mined in the form of limestone and viewed as a valuable commodity. In a time of increased awareness of the need for a circular economy, the aquaculture and seafood industry should consider shells as a valuable biomaterial that can be reused for both environmental and economic benefit. This review discusses the current waste shell issue and identifies large‐scale shell applications that are already in place. Further, it highlights proposed applications that have the potential to be scaled up to address the problem of waste shell accumulations and reduce our reliance on environmentally damaging incineration and landfill disposal. Of the plethora of shell valorisation techniques proposed in the scientific literature, this review will focus only on those that can incorporate large‐scale shell utilisation, and do not require high‐energy processing, and are thus; simple, sustainable and potentially economically viable. Further, this review questions whether, in many cases, shells can provide more inherent value being returned to the marine environment rather than being used in land‐based applications.

“…On the other hand, it is important to remark that currently there is no standard to assess the permeability for PC [28]. Concerning that, two types of test are commonly used to measure the permeability coefficient: the falling head permeability test [3,8,10,11,38] and the constant head permeability test [39][40][41][42][43][44].…”

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.
