Modelling Reviewed Hydraulic Indices of Periwinkle Shell Ash Occasioned by Variations in Calcination Temperature

International Journal of Mechanical and Civil Engineering, 2022
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 ...

Deciphering mollusc shell production: the roles of genetic mechanisms through to ecology, aquaculture and biomimetics

Biological Reviews, Volume 95, Issue 6, Page 1812-1837, December 2020., 2020
ABSTRACT Most molluscs possess shells, constructed from a vast array of microstructures and architectures. The fully formed shell is composed of calcite or aragonite. These CaCO3 crystals form complex biocomposites with proteins, which although typically less than 5% of total shell mass, play significant roles in determining shell microstructure ...

Water Treatment for Fish Aquaculture System by Biochar‐Supplemented Planting Panel System

The Scientific World Journal, Volume 2020, Issue 1, 2020., 2020
Rice husk biochars were prepared by carbonization at 400–600°C. The products were analyzed by FTIR, SEM‐EDS, BET, and approximate analysis in order to find final products with the best properties and the lowest carbonization temperature. It has been found that the biochar prepared at 500°C, which has 37.86 ± 0.11% yield, 341.0776 m2/g of BET surface ...

POTENTIAL APPLICATION OF A LOCALLY SOURCED PHOTOCATALYST FOR THE PHOTOCATALYTIC DECOLOURISATION OF METHYL ORANGE IN AQUEOUS SOLUTION [PDF]

Journal of Engineering Science and Technology, 2015
Periwinkle shell ash (PSA) was investigated for its photocatalytic properties in decolourising methyl orange in aqueous solution. The effects of irradiation time, initial dye concentration and PSA dosage on the decolourisation process were investigated ...

Sulphate Induced Strength Loss Index Optimisation of Periwinkle and Clam Shell Ash Hybrid Pozzolana Concrete

International Journal of Advances in Scientific Research and Engineering, 2021
The globe yearns for sustainability in meeting the present and future needs of man. Hence, research into a more sustainable modes of harvesting, processing and use of nature’s raw resources is evidently timely. Cement replacement is opined on the need to reduce the environmental as well as economical limitations associated with its production, while ...

Evaluating the Fluid Loss and Carrying Capacity of Water‐Based Muds Treated With Wheat Husks and Periwinkle Shells

Journal of GeoEnergy, Volume 2025, Issue 1, 2025.
The formulation of drilling fluids with the desired characteristics required to achieve a successful drilling operation depends largely on the drilling additives. In this study, we investigated the potential of two agrowastes, wheat husks (WHs) and periwinkle shells (PSs) as additives in water‐based drilling fluids (WBFs).
