Palm oil clinker as drainage layer in green roof system under Malaysia climatic conditions. Journal of Engineering and Technology, 5 (2). pp. 27-37. ISSN 2180-381 (2014)
Abstract
This paper reports on the potential of using palm oil clinker as drainage layer in green roof system as replacement of conventional materials (expanded clay, expanded shale, pumice, etc.). The ability for draining of palm oil clinker is studied since the purpose of drainage layer is to drain the excess water and to ensure aeration of substrate layer and root. This study used an experimental procedure in which hydraulic conductivity, infiltration rate and bulk densities were measured. Besides, the plant developments of selected green roof plants were also monitored to see any effect from the palm oil clinker replacement by means of experimental trays to simulate the real green roof system. It was found that palm oil clinker has a good ability of draining the excess water and there is no side effect in term of plant development. This indicates that there is a possibility of using palm oil clinker as drainage layer in green roof system.
