Determination of Properties and Heat Transfer Rate through building boundary of Corn Cob Cement Material for Applying to be Construction Material

摘要

In order to reduce heat transferring through building boundary affecting the increase of energy efficiency, the development of property of construction material is significant. An effective way to be used is the utilization of agricultural waste, biomass such as palm, bagasse, coconut shell which has fiber structure, mixing with cement material to be formed as concrete. This research aims to develop and test the property of concrete, which have structure of mixing between corn cob and cement material. With the large amount of agricultural residue, corn cob is selected for this study. Test of physical, mechanical and thermal properties of corn cob cement material is performed. Comparison of property of cement materials consisting of different types of fibers, corn cob, palm, bagasse, coconut shell, is investigated one another. Two house models consisting of the structure of pure and corn cob cement materials with the same size of 2 x 2 m2 in each are fabricated. Each house is positioned to face to the sun all day. Conduction heat transfer rate passing through boundary in each house models is determined and compared each other. Evaluation of suitability of use of corn cob cement material for applying with construction purpose is given.
