PRECAST CONCRETE ON BEAM COLUMN CONNECTION USING COCONUT SHELL BY EXPERIMENTATION

One of the sustainable alternative aggregates is coconut shell (CS) and coconut shell concrete (CSC) was established a decade ago. CSC precast elements and their behavioral studies are very limited. Joints capacity and behavior are significant in precast concrete elements. Hence, in this study precast column — beam behavior of CSC elements was studied. To start with, to connect the precast elements two different sizes 12 and 16 mm bolt and nuts connection was selected and used. The same sectional details were also used and specimen were produced with conventional concrete (CC) for comparison purpose. Monolithic elements of both CC and CSC were also cast and tested. Failure of both monolithic and precast CSC elements specimen were typical structural failure and are comparable to that of CC, High deflection were observed on CSC element compared to CC. No cracks were formed on precast specimen both in CC and CSC. All elements were able to achieve their full strain capacity. However, there are some deficiency faced in this study like occurrence of slip in precast elements.
