Study for the relevance of coconut shell aggregate concrete non-pressure pipe

The general behaviour of coconut shell aggregate concrete pipe is comparable to that of conventional concrete pipe. Three-edge bearing test results show that, both coconut shell aggregate concrete and conventional concrete pipes abide more load than load specified as per IS 458: 2003. The application of hydro static pressure not resulted in the formation of beads of water on the pipe surface during the application of the test pressure of 0.07 N/mm2 as per IS 458: 2003. Absorption properties of both coconut shell aggregate concrete and conventional concrete pipes are well within the allowable limits as per IS 458:1988 on the conditions specified. Test results and performance of coconut shell aggregate concrete pipes encourage the use of coconut shell as an aggregate for the replacement of conventional coarse aggregate in reinforced concrete pipes production.
