Strength Performance Of Coir Fiber Concrete With Wollastonite As Partial Cementitious Material To Control Global Warming

Abstract

In construction of structures, adding cementitious and supplementary materials to cement concrete has grown to reduce costs, save energy, and protect the environment. Wollastonite is a natural mineral (CaSiO₃), When it hydrates calcium Silicate –calcium-silicate-hydrate compound will be formed and it strengthens cement. ​The high availability and low demand of Wollastonite has subsequently increased the chances of implementation in cement concrete technology to reduce the carbon foot print. Since the availability of coir fiber in nature is abundant and will become more economical to use as reinforcement in concrete due to its crack reduction capacity. This work is focused on compressive and tensile strength performances of coir fiber concrete under the influence of wollastonite as partial cementitious material. The addition of coir fibres is kept constant as 0.6% by weight of cementitious material. Wollastonite as cementitious material replaced the cement in varying proportions of 0%, 10%, 12.5%, 15% and 17.5% by mass of cement. Both the strengths of coir Fiber concrete were studied under the influence of wollastonite.  10% wollastonite by mass of cement influences for better strength in coir fiber concrete.
