They observed that % and % of the periwinkle shell in replacement for granite was quite satisfactory for compressive strength when using concrete get price
· The hard shells are regarded as waste which are accumulated in many parts of the country. In our project, those shells are used as partial coarse aggregate replacement in concrete which is an effort towards protecting natural coarse aggregate for future generation. Coarse aggregate is partially replaced with 0%, 5%, 10% 15% by oyster shells.

kernel shells and periwinkle shells as coarse aggregate in lightweight concrete. Palm kernel shell was partially a waste in the 1990s and early 2000, more than 350,000 tons were available for sale, especially in concrete work (Mohammed, 2007). The aim of this study is to compare the performance of palm kernel shell concrete and periwinkle shell ...
· 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).
periwinkle shell as partial replacement for river gravel (coarse aggregate) in concrete. The study discovered that concrete cubes with periwinkle shells alone as coarse aggregate were lighter and of lower compressive strengths compared to those with other periwinkle.
periwinkle shells (Tympanotonus Fusus) to replace coarse aggregates in lightweight concrete,  employed the periwinkle shells as hybrid biocomposite material, while  reported that  employed the cementitious properties of the periwinkle shell ash as a filler for partial replacement of
Experimental Study on Palm Kernel Shells as Coarse Aggregates in Concrete Daniel Yaw Osei, Emmanuel Nana Jackson Abstract— This paper reports on experimental investigations on the effects of replacing crushed granite in concrete with palm kernel shells on the strength, density and workability of concrete.
Periwinkle shell ash as a filler material to improve the performance of the asphaltic concrete is considered. In this study, the mechanistic properties of asphalt concrete mixes modified with Periwinkle Shell Ash as a replacement for mineral filler were evaluated at 20 percent. Bitumen content were evaluated and six.. Expand.
potential of periwinkle shell as coarse aggregate for concrete. The results showed that concretes produced with 1:1:2, 1:2:3 and 1:2:4 mixes indied compressive strengths of N/mm 2, N/mm and N/mm 2 at 28 days curing age respectively. These strength values met the ASTM77 recommended minimum
