“…The cellular structure and porous nature of OPS are largely responsible for PKS's high water absorption and low specific gravity values (Alengaram et al, 2011). According to Ogundipe et al (2021), the understanding of the water absorption value of aggregate is essential in developing the ideal water-cement ratio for the concrete mix proportion. PKS exhibited lower bulk density value than river sand and granite as revealed in the results in Table 2.…”

The evaluation of agro-industrial by-products as alternative construction materials is becoming more significant as the demand for environmentally friendly construction materials increases. In this study, the workability and compressive strength of concrete produced by combining Palm Kernel Shell (PKS) and Rice Husk Ash (RHA) was investigated. Concrete mixes using a fixed content of 15% RHA as replacement for cement and 20, 40, 60, 80 and 100% PKS as replacement for crushed granite by volume with the mix ratios of 1:1½:3, 1:2:4 and 1:3:6 were produced. The water-to-cement ratios of 0.5, 0.6 and 0.7 were used for the respective mix ratios. Concrete without PKS and RHA served as control mix. The fresh concrete workability was evaluated through slump test. The concrete hardened properties determined were the density and compressive strength. The results indicated that the workability and density of PKSC were lower than control concrete, and they decreased as the PKS content in each mix ratio was increased. The compressive strength of concrete at 90 days decreased from 27.8-13.1 N/mm2, 23.8-8.9 N/mm2and 20.6-7.6 for 1:1½:3, 1:2:4 and 1:3:6, respectively as the substitution level of PKS increased from 0-100%. However, the compressive strength of concrete increased with curing age and the gain in strength of concrete containing RHA and PKSC were higher than the control at the later age. The concrete containing 15% RHA with up to 40% PKS for 1:1½:3 and 20% PKS for 1:2:4 mix ratios satisfied the minimum strength requirements for structural lightweight aggregate concrete (SLWAC) stipulated by the relevant standards. It can be concluded that the addition of 15% RHA is effective in improving the strength properties of PKSC for eco-friendly SLWAC production..

“…Periwinkles are univalent invertebrates, a relatively cheap source of animal protein belonging to the Phylum Mollusca [29]. Periwinkles shells exist in "V" as a spiral shape, and a circular aperture are small greenish-blue marine snails while in texture it is brittle but very sturdy [30,31]. By constantly attaching the shell to the outside, the mollusc creates this spiral shape, coiling along an imaginary axis passing directly through the shell [32].…”

Periwinkle Shell as Mixing Ingredient in Concrete: A Review

et al. 2021

Growing population which also pushes for rising demand for seafood results in a generation of seashells which are thrown as environmental pollution waste after the edible meat is consumed. Meanwhile, the utilisation of natural resources as mixing ingredients for the production of concrete materials continues to increase over the year. The use of periwinkle shells as mixing ingredients in concrete materials can lower the dependency on natural aggregate supply. This paper discusses the properties of periwinkle shell and method of treatment prior to their usage as a cement and coarse aggregate as well as the mechanical properties of concrete produced using this seashell waste. Overall, the replacement of periwinkle shell as cement and coarse aggregate must be integrated in a specified percentage to enhance the performance of the concrete. For cement replacement, 5% of replacement gives the highest strength, meanwhile 10% of replacement as coarse aggregate can meet the desired strength. The increase in the use of periwinkle shell quantity as cement or coarse aggregate replacement reduces concrete workaibility. The integration of periwinkle shell influences the compresssive strength of concrete. Accomplishment in replacing periwinkle shell as cement and coarse aggregate would reduce pollutiion due to shell dumping and save natural resources. However, further investigation in terms of durability properties is recommended.

“…This quantity will be constantly increasing in view of the various actions carried out by successive governments to relaunch this sector which currently contributes only 43% of the demand and needs of fatty substances of plant origin in Benin [10,11]. Recently, several studies have dealt with the problem of the use of PKS as large aggregates to replace gravel for making structural concrete for buildings [12][13][14][15]. To date, few studies have been interested in the recovery of this waste (aggregates) in road engineering.…”
