Study on Thermal Performance for Straw Fiber Concrete Hollow Block

Abstract

In this paper, based on ansys studies for thermal performance of concrete hollow block which were conducted on the content of 5% and 15% of the straw plant fiber, and get temperature distribution and the law of heat of the blocks which suffer the load of convection, then calculate the mean coefficient of thermal conductivity and thermal resistance based on the data block obtained. The results show that mixed plant fiber can effectively improve thermal performance for the concrete hollow block,and better insulation effect,thus can provide the basis for the promotion of plant fiber building block materials.
