The suitability of periwinkle shells as coarse .

The results of an exploratory investigation on the suitability of periwinkle shells as coarse aggregate for concrete are reported. The tests show that the strength of concrete made with periwinkle shells are limited by the strength of the shells but high enough for structural concrete. The modulus of elasticity and modulus of rupture are low compared with normal gravel concrete.

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.

Use of Sea Shells as Aggregate in Concrete

Sea Shell Concrete IV. CONCLUSION This early study found that expansion of sea shell as fractional coarse aggregate substitution decreases the solid workability inferable from its shape and rougher surface. Notwithstanding, it is fascinating to note that substitution of common coarse aggregate via sea shell at a level of 20 %
