The crushing values of cockle shell and periwinkle shell were approximately more than the recommended value of ACI for normal concrete by 19% and 30%, respectively. Mussel shell achieved the specification for Los Angeles coefficient, and ...
Periwinkle shell (PS) has been found to be a good lightweight material for concrete production. PS can be used to either partially or totally replace aggregates in concrete, yet achieve the desired properties [16and 15]. The continuous dumping of Rice Husks and Periwinkle shell has resulted and constituted
The periwinkle gravel concrete cubes were tested for its compressive strength. The bulk density of the periwinkle shells was found to be 515 kg/m3 while that for river gravel was found to be 1611 kg/m3. Concrete cubes with periwinkle shells alone as coarse aggregate were lighter and of lower compressive strengths compared to those with other ...
Studies have shown that climate, traffic conditions, characteristics of the asphalt binder and the aggregate are the main factors that can contribute to premature pavement failures. The ability of periwinkle shell ash as filler to improve the fatigue and rutting resistance of Hot Mix Asphalt (HMA) as well as moisture sensitivity was investigated.
investigation of the suitability of using periwinkle shell as coarse aggregate for making concrete in such coastal communities. Periwinkle shell is an agricultural waste material commonly found in coastal communities. They are relatively non-degradable, and, as such, constitute a great deal of environmental problems. Many of these

The fine aggregates and coarse aggregates were replaced with lateritic sand and materials [2]. The evolution of alternative aggregate periwinkle shells respectively at 10%, 20%, 30%, 40% materials is believed to be key to promoting research and .
periwinkle shells (Tympanotonus Fuscatus) to replace coarse aggregates in lightweight concrete, [12] employed the periwinkle shells as hybrid bio-composite material, while [7] reported that [17] employed the cementitious properties of the periwinkle shell ash as a filler for partial replacement of

Jan 01, 2019· Periwinkle shells are one of the most common molluscs used in concrete and are used as a substitute for natural coarse (Falade, 1995, Adewuyi and Adegoke, 2008, Osarenmwinda and Awaro, 2009) and fine aggregates (Nguyen et al., 2013).
The potential of periwinkle shell as coarse aggregate for concrete was studied in this paper. The properties of concrete made with periwinkle shell as coarse aggregate were examined. Test conducted on the concrete was compressive strength test. Prescribed mix designs of 1:1:2, 1:2:3, 1:4:6, 1:2:4 and 1:3:5 were used to produce concrete cubes used for testing.
24% savings in cost when periwinkle shells are used holistically () as coarse aggregate and 6.8% savings in cost when 30% are used to replace granite as coarse aggregate. Keywords—periwinkle shells, mechanical properties, concrete, compressive strength, fine aggregate, coarse aggregates I. INTRODUCTION
Periwinkle shell has an aggregate crushing value of 10% and an aggregate impact value of 21%, these implies that the shell has a higher strength and as such it can be used for construction of heavy duty floor finishes. The compressive and flexural strength of the concrete produced were found to depend to some extent on the physical strength of ...
Jun 22, 2019· The effects of periwinkle shell, curing duration and methods of curing on the compressive strength of concrete using response surface methodology were evaluated. However, the periwinkle shells were added to the concrete at 5%, 10% and 15% dosage by weight as partial replacement to the coarse aggregate. The concrete were cast at 0.5 w/c ratio and cured between 7 …
The periwinkle shells used for this study were obtained from heaps at Okrika waterside, by Hospital Road, Port Harcourt, Rivers State, Nigeria. The length varied from 31.8mm to 63.96mm and diameter of about 16.9mm near one end and tapering to a point at the other end. The periwinkle shell aggregates were thoroughly washed
