Preparation and Characterisation of Periwinkle Shell Ash Periwinkle shells were sourced locally from Benin City in Edo State of Nigeria. The shells were washed and dried in an oven at 110 oC to constant mass, followed by crushing and calcination at 600 oC in a muffle furnace and subsequent sieving to obtain fine particles (< 350 µm) of ...
A series of tests were performed to determine the chemical composition of coconut husk ash, corn cob ash and peanut shell ash which are referred to as CHA, CCA and PSA respectively.
The chemical composition of the ash was determined and compared with the specifications of American society of testing and material. Compressive strength of percentage replacement of cement with periwinkle shell ash of 0, 10, 20, 30 and 40% at 28 days of curing was also determined with mix ratio of 1:1:2 and 1:2:4. Periwinkle shell ash
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.

And Rice Husk Ash, Pulverised Fuel Ash (PFA), sawdust ash, corn ash and so on to partially replace cement [12, 5, and 20]. The problem is that none of the previous researchers have attempted to study the
BEHAVIOUR OF PERIWINKLE SHELL ASH BLENDED CEMENT CONCRETE IN SULPHURIC ACID ENVIRONMENT I. C. Attah et al Nigerian Journal of Technology, Vol. 37, No. 2, April 2018 316 admixtures have been fly ash, blast furnace slag, silica fume and rice husk ash.
The study therefore concluded that Periwinkle Shell Powder (PSP) could be considered as good stabilizer for clayey or lateritic, and its uses as a stabilizer could also provide a big relief to the environmental pollution caused by its indiscriminate dumping. Keywords: Periwinkle Shell Powder, Geotechnical Property, Expansive soil, Stabilization. 1.
Composition Variability in assessment. Many studies have been conducted regarding the chemical composition of wood ash, with widely varying results. Some quote calcium carbonate (CaCO 3) as the major constituent, others find no carbonate at all, but calcium oxide (CaO) instead.
The proximate, nutritionally valuable minerals, functional properties and amino acids composition of periwinkle (Tympanotonus fuscatus var radula) meat were studied. The results showed that the sample contains % ash, % moisture, % protein, % fat, .

Chemical Analysis of Ground Shell Ash (GSA) Chemical analysis was carried out on samples of GSA and ordinary Portland cement (OPC) to reveal and compare their composition, and the result shown in table 1. The percentage composition of the constituent compounds in the GSA is compared to that of typical ordinary Portland cement (OPC).
Aug 04, 2020· The snail shell ash was then sieved to obtain a fine powder of 75 μm. The chemical composition of the recycled SLSG is based on the work of Owoeye et al. while that of SSA is according to Rimruthai et al. as shown in Table 1. Fig. 1(a–d) indicates .
In recent times, many waste materials like fly ash periwinkle shell ash, and ashes produced from various agricultural wastes such as palm oil waste, rice husk ash, corncob ash, millet husk ash, groundnut husk ash have been tried as pozzolanas or secondary cementitious materials.
The aim of the research is to investigate the influence of periwinkle shell ash (PSA) and Periwinkle shell dust (PSD) on the compressive strength of concrete. Objectives: The specific objectives include i. To determine the oxide composition of both periwinkle shell (ash and dust) using Xray Florescence Analysis (XRF). ii.
