Two Stage Procedure for Assessment of In Situ Compressive Strength of Bamboo Reinforced Beams Using Non Destructive Tests

Abstract

‘Bamboo’ is used in place of structural as well as reinforcing steel because of its good physical and mechanical properties, shrinkage and average density. It can be considered as well established building material for the developing countries such as India, Africa and South America etc. although the implementation techniques, suitable connection techniques are need to be improving. In this study in first stage singly bamboo reinforced beams and cubes of conventional mix grade from M 25 to M 40 were casted and two different Non Destructive Test methods, Schmit Hammer and Ultasonic Pulse Velocity as well as destructive test using compression testing machine were carried out in second stage Statistical Regression technique applied on the results obtained from two different Non Destructive Test methods, Schmit Rebound Hammer (RN) and Ultasonic Pulse Velocity (U) and destructive test results in order to derive correlation of compressive strength (y) of bamboo reinforced concrete.
