Influence of Periwinkle Shell Ash on the Strength Properties of Cement-Stabilized Lateritic Soil

International Journal of Pavement Research and Technology, 2021
The study investigated the use of Portland limestone cement (PLC) and periwinkle shell ash (PSA) under laboratory conditions on geotechnical properties of lateritic soil to enhance its suitability as pavement layer material. The soil was treated with varying percentages of PLC at 0–8% and PSA at 0–10% (each at an increment of 2%) and compacted using ...

Investigating the Relationship Between Workability and Water Absorption of Periwinkle Shell Ash Cement Concrete [PDF]

International Journal of Transportation Engineering and Technology, 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.
