Conventional concrete is strong in compression but weak in tension. In the Conventional reinforced concrete, the benefits of steels are reinforced. To extract the maximum benefit of concrete and steel, a new form of sandwich construction, called steel-concrete-steel construction, has been developed in recent years. Also, many researchers are working for the replacement of conventional constituents. Therefore, in this project, a new steel-concrete-steel is tried with coconut shell as coarse aggregate and quarry dust as fine aggregate in the production of concrete. Totally eight beams were cast and tested for flexural behavior. There are two cases has been taken into consideration, one is without stud and with a stud. In each case four beams were cast one with conventional concrete with river sand (CCS), second with conventional concrete with quarry dust (CCQD), third with Coconut shell concrete with river sand (CSCS), fourth with Coconut shell concrete with quarry dust (CSCQD) respectively. All the beams were tested for their flexural behavior and the parameters like initial crack load, ultimate load capacity, deflections, and strains on compression plate, tension plate and also on concrete zone were studied. Test results are shown that coconut shell concrete sandwich beams behaves similar to that of conventional concrete beams and are conservatives.
