The Periwinkle shell (Tympanotonus fuscatus) is one of the most abundant wastes in the Calabar coastal region of Nigeria and needs to be put into proper use. The great need to shift attention towards waste materials with good mechanical properties to replace some materials used in the Automobile industries for Automobile products is paramount. This research focused on the Mechanical characterization of several composites developed from Periwinkle Shell Powder (PSP) as filler and four selected polymeric materials as the matrix.

Periwinkle shellfish can be found in abundance in the Niger Delta's wetlands. Periwinkle shells are frequently piled in open fields and landfills, resulting in pollution and the development of disease-carrying organisms. Attempts have been made to employ periwinkle shell ash (PSA) as recycled materials in cement-based products in order to manage periwinkle shell by-products, preserve natural resources, and minimize building expenses. A better understanding of results obtained can be established using statistical tools in the analysis and modelling of the trends established with respect to revi

Recently, the stabilization of clayey soil (CS) has drawn the attention of numerous researchers. In the past, Egg Shell Powder (ESP) and Periwinkle Shell Ash (PSA) were individually tested for their ability to stabilize clayey soil. The author has attempted to stabilize the clayey soil by combining the two of them. The goal of the current study was to compare the efficacy of various eggshell powder and periwinkle shell ash concentrations as soil stabilizers. Testing procedures include the California Bearing Ratio (CBR), Atterberg limits, Unconfined Compression Test (UCS), and compaction tests

Abstract In this study, the shell powder of Littorina littorea commonly called periwinkle was used as an eco-friendly filler in High-Density Polyethylene (HDPE) to form periwinkle/HDPE composites (PHPC). Understanding the effect of different particle sizes of periwinkle shell powder (PSP) and optimizing their influence on PHPC is the main scope of this work. Periwinkle shell (PS) particles with sizes ranging from <53 μm to 150 μm were chosen as reinforcements. The PSP sizes chosen in this study, <53 μm, 53 μm, 75 μm, 90 μm, 105 μm and 150 μm were named PHPCL53, PHPC53, PHPC75, PHPC90, PH

AbstractThe usage of plentiful raw discarded resources in the manufacturing of concrete has proven to be a sustainable and environmentally beneficial method of making concrete for a variety of purposes. In this study, the physical and mechanical properties of concrete made by partially and fully substituting fine aggregates and ordinary Portland cement with periwinkle shell ash and quarry dust (5%, 10%, 15%, 20%, and 100%), respectively, were examined. The ratio of water to cement utilized for the concrete mixture, 1:2:4, was 0.60. Fresh concrete underwent a slump test, and then 150-mm cubes o

Reservoirs that contain acidic gases can lead to the corrosion of the drilling string and casing which could result in incessant down time and also increase the cost of drilling operation. This research work aimed at investigating the potential of using locally sourced materials such as Periwinkle Shell Ash (PSA) that can serve as substitutes to imported chemicals used in the industry, to help raise the mud pH to the API standard (9.5-12.5) whilst reducing the cost of drilling operation. Calcium hydroxide (Ca (OH2)) was extracted from Periwinkle Shell using two different process routes (via th

Abstract Combined adsorption and photocatalysis synergy was explored in this research because the porosity of activated carbon and hydroxyl radicals' generation are the main drivers of the adsorption and photodecomposition efficiency of dyes. In this study, periwinkle shell ash (PSA) activated at 800 °C was used for the adsorption of toxic crystal violet (CRV) dyes. The PSA was characterized by scanning electron microscope, Fourier transform infrared spectroscopy, thermogravimetric analysis, Brunauer–Emmett–Teller surface area analysis, and X-ray diffraction. Findings showed that CRV adsorptio

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
