2.2 Periwinkle Shell Ash The periwinkle shell was obtained from a dumpsite located in Uyo, Akwa Ibom State, Nigeria. It was calcined to a tempera-ture of 1200oC and allowed for about an hour inside the oven. The calcined shell was brought out of the oven, and allowed to cool and further pulverized to powdered form. The pulverized

KOH/g. Periwinkle shell was obtained from Ihiagwa Market after the edible portion had been harvested. The shells were soaked in water for one week to thoroughly remove impurities. They were dried, ground and sieved to three particle sizes of 150, 300 and 425 μm. The chemical composition of the periwinkle shell is as shown in Table 1.
Calcium silicate was successfully synthesized using agricultural byproduct such as rice husk ash and shell of snail namely Pomacea canaliculata by solid state reaction. Chemical composition of silica in rice husk ash and calcium oxide in shell were 91.50 and 98.25%, respectively by X-ray fluorescent determination. The rice husk ash and shell in molar ratio of 1:1 were milled for 5-8 hr and ...

Dec 04, 2012· Abstract: The study investigated the effect of periwinkle shell ash (PSA) as cement substitute on the strengths of concrete. Specimens were prepared from a mix of designed strength 25 N∕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 days.

May 02, 2019· In this paper, a comprehensive study on the relationship between workability in form of slump and water absorption, a permeability and durability property, of cement concrete blended with periwinkle shell ash is presented. Periwinkle shell ash was obtained from the granulation process of calcined periwinkle shells at a calcination temperature of 800°C.
Periwinkle shells were heated in a furnace to a temperature of 850 °C, where they were turned into their carbon ash. This was done in order to reduce their hydrophilic properties and the percentage composition of moisture [8]. Processing ofthe Composites Periwinkle shell ash .
