The indiscriminate disposal of periwinkle shells as agricultural waste at landfills has saddled geo-environmental engineers with the responsibilities of reutilizing these wastes as construction materials for dual purpose of soil stabilization and effective waste disposal. In this research, lime and periwinkle shell ash (PSA) under laboratory conditions

Morphology and properties of periwinkle shell asbestos-free brake pad [PDF]
Journal of King Saud University, Engineering Sciences, 2016 The development of asbestos-free automotive brake pad using periwinkle shell particles as frictional filler material is presented. This was with a view to exploiting the characteristics of the periwinkle shell, which is largely deposited as a waste, in ...

Strength Characteristics of Periwinkle Shell Ash Blended Cement Concrete
International Journal of Architecture, Engineering and Construction, 2012The study investigated the eect of periwinkle shell ash (PSA) as cement substitute on the strengths of concrete. Specimens were prepared from a mix of designed strength 25N=mm 2 and the replacement of cement with PSA was from 0% up to 40%. A total of 180 specimens were cast and tested for compressive and tensile splitting strength at 7 and up to 180 ...

Bioremediation of Crude Oil Polluted Soil Using a Blend of NPK Fertilizer and Periwinkle Shell Ash
Journal of Engineering, Emerging Technologies and Applied Sciences, 2023Analysis on the bioremediation of crude oil polluted soil using a blend of NPK (15-15-15) fertilizer and Periwinkle Shell Ash (PSA) is presented. The analysis involves using 7-batch bioreactors under aerobic conditions with each bioreactor containing 2 kg of soil sample and spiked with 200 ml of crude oil except for the control experiment, and were ...

The potential of locally sourced periwinkle shell ash (PSA) has been explored as an alternative photocatalyst for the photocatalytic decolourisation of Congo red dye. The effect of process parameters such as irradiation time, initial dye concentration, catalyst dosage, pH of the solution and the addition of hydrogen peroxide (H2O2) on the extent of ...
