Ground seashell aggregate can replace up to 20% natural fine aggregate in concrete. • Up to 50% seashell as a partial coarse aggregate can give normal-weight concrete. • Current data on durability of seashell aggregate concrete indicate varied effects. • Sound absorption and thermal insulation studies of seashell concrete are required.
shell as course aggregate. SCOPE OF THE WORK: The point of this study is to study the utility and profitability of coconut shells as a coarse aggregate as a contrasting option to characteristic aggregate in cement. 1. This trail work was held to acquire the quality …
Up to 50% seashell as a partial coarse aggregate can give normal-weight concrete. Current data on durability of seashell aggregate concrete indicate varied effects. Sound absorption and thermal insulation studies of seashell concrete are required.
21-02-2017· Coconut shells are more suitable as low strength-giving lightweight aggregate when used to replace common coarse aggregate in concrete production. In the following paper the normal weight aggregate has been replaced by coconut shell aggregate and cubes have been casted to test their compressive strength and other physical properties.
Partial Replacement of Coarse Aggregate with Demolished ... "Use of demolished concrete waste in partial replacement of coarse aggregate in concrete" SSRG International Journal of Civil Engineering (SSRGIJCE) – volume 3 In this paper, it is discussed that there is a large amount of demolished waste generated every year in India and other developing countries.
17-04-2021· 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.
coarse and fine aggregate replacement in concrete' have written a journal by integrating the cockle shells as partial coarse and fine aggregate replacement which could reduce consumption of natural fine aggregate use. Following were 4 types of mix used in this study. • Plain concrete with of natural coarse and fine aggregate.

with Fly Ash And Coarse Aggregate With Sea Shells In Concrete Suryawanshi Vinod Vyankatesh1, A.N. Shaikh2 1, 2 Dept of Concrete Technology 1, 2 M.S.Bidve Engineering College,Latur Abstract- The project "Experimental Study on partial Replacement of cement with Fly Ash and Coarse Aggregate with Sea Shells in Concrete" deals with the Eco Friendly
seashell. Further coarse aggregate is replaced with seashell of about 10% along with the partial replacement of cement with fly ash. The cement is replaced with 5%, 10%, and 15% by fly ash. The design mix used to execute this project is M20 grade concrete.
The concrete samples were prepared by adding seashells about 0%, 10%, 20%, 30% and 40% as a partial replacement to coarse aggregate. All these samples were cured for 7 days, 14 days and 28 days before the compressive, split tensile and flexural test were carried out.
