“…Moreover, 30% replacement of sharp sand by PSA was a satisfactory mixture ratio for lowcost/lightweight buildings as well as 6.8% costsavings [50,51]. The results also agreed with the research findings of several previous publications [34,40,47]. Moreover, the cost savings were low compared to an earlier finding that made savings of 14-17% using 35-42% PSA [36].…”

“…Although research findings confirmed that NaNO 3 can improve the compressive strength and splitting strength performances of concretes [47], nevertheless it was sufficient to be classified as a load-bearing concrete. Hence, advances in concrete developments to achieve pillar strength status and weight/load bearing status are required for the improvement of PSP and PSA blended concretes.…”

“…As the exploration of periwinkle shell continues to grow, researchers sought organic and inorganic supports to enhance concrete composites that contain PWS. Researchers now examined the effect of sodium nitrate as an accelerator in PSA blended with cement concrete [47]. Optimum concrete blend performance was achieved when PSP was 30% content and only 2% of NaNO 3 .…”

The choice of building materials and the rising cost of construction materials have continued to plaque the building and construction industry without an immediate solution. Industrialists and scholars are investigating several naturally occurring materials for concrete composite reinforcements. The article chronologically reviewed the growth and development of periwinkle shell powder (PSP) and periwinkle ash powder (PSA) as composite materials in concretes. Findings showed that 28 days of curing age are required for lightweight concretes reinforced with PSP or PAP at 10-30% optimum. Produced lightweight concretes were susceptible to acidic medium and induce lower compressive strength which eventually leads to concrete/structure disintegrate and collapse. Research challenges and funding hamper the application of PSP/PAP in the concrete formulation and are unable to drive innovations and economic benefits as a composite. Advances in concrete technology showed that PSP/PSA mollusk shells achieve pillar strength grade and weight/load bearing status for the improvement of PSP/PSA blended concretes. Also, the composite potential showed that the functionalization of PSP/PSA, sustainability, and nano modification of cementitious materials and concretes are promising. Future studies are required to develop periwinkle reinforced concrete silos, sewers, and smart concrete materials with improved mechanical, thermal, and aesthetic properties.

“…The increasing rate of production has consequentially led to increased generation of waste shells. Shells such as periwinkle have in the past years been used by locals for minor constructions in the Niger-Delta regions [42][43][44], while a majority is continuously accrued and abandoned in open lands, constituting in environmental pollution.…”

This research appraised the effects of recycling senilia senilis waste seashells as a full or partial substitution for natural coarse aggregate (granite) in eco-friendly concrete production. The design mix employed a 1:2:4 concrete mix ratio for M25 grade, a w/c ratio of 0.5, river sand as fine aggregate, ordinary Portland cement (OPC) as a binder, and varying proportions of crushed seashells and granite as coarse aggregates (0:100, 10:90, 20:80, 30:70, 40:60, and 50:50). Laboratory tests revealed that workability requirements were only met with a 10%-40% seashell addition, workability decreased with increasing seashell percentages. The compressive strength increased with curing age but decreased with the additions of seashells. The seashell-modified mixes failed to reach the design target strength for M25 concrete. Nonetheless, the 10 and 20% seashell-modified mixes achieved the required strength for M20 concrete. Split tensile strength increased with curing age for all mixes, the seashell-modified mixes yielded slightly reduced tensile strength values compared to the unmodified mix at all curing stages. However, the 10%, 30%, and 40% seashell-modified batches attained recommended split tensile strength values on the 28th day. Furthermore, high correlations were observed between the datasets of the some of the measured parameters, and variations for Split tensile strength as a function of seashell percentage and compressive strength were developed discretely by fitting the experimental data to the numerical models. Relationships were also developed for compressive strength and workability as functions of seashell percentage. Eco-friendly building construction recycling waste seashells is encouraged as it offers positive economic and environmental prospects.

“…Seashells are primarily composed of CaCO 3 [12]. As such, recycling has been widely studied as a source of CaCO 3 or as CaO [16][17][18][19][20][21]. Seashell wastes were used in 15th-century Latin America as a raw material for the manufacture of Tabby concrete [22].…”

Assessing Durability Properties and Economic Potential of Shellfish Aquaculture Waste in the Construction Industry: A Circular Economy Perspective

et al. 2022

The construction industry’s high demand for natural resources, combined with the waste generated by agriculture, creates an opportunity for the circular economy. This experiment used the CaCO3 found in scallop shells as an ingredient for the manufacture of fire-resistant materials, replacing gypsum in compositions of 40% and 50% by weight. The mechanical compressive strength was estimated for both freeze-thaw cycles and acid and sulfate attacks. The cost of disposing of scallop shell waste in landfills, savings from substitution, and the payback period relative to the amount of production were determined. The compressive strength of the materials decreased by 80% when subjected to freeze-thaw cycles and sulfate attack. In response to acid attack, they showed a 100% increase in strength during the first three weeks and a decrease thereafter. The savings amounted to $46.36 (22.4%) for 40% replacement and $58.93 (28.4%) for 50%. Respectively, return on investment is achieved at 800- and 630-per-metric ton produced. The difference between the costs of waste disposal (in aquaculture) and the potential savings from using CaCO3 as a raw material (in construction) creates an opportunity for commercialization between the two industries, serves as a reference for decision-makers, and complies with circular economy principles, reducing both inputs of raw materials and outputs of waste.
