Abstract

The study includes the preparation of fiber-cement panels made from the husks of rice paper and old newspapers, which are used in the prefabricated building panels, and manufacturing of these panels using two types of polymers as materials. The flexural strength reaches 6.99 MP compared with imported panels of 3.5 MP; thus these manufactured panels are resistant to combustion. The present study used rise husk with waste of newspaper at different rate in addition to cement and polymer materials consist of poly vinyl astate (PVA) and poly ol (PO) with rate (3:1) respectively. Physical and mechanical properties were determined in this study. In this paper rice husk fibers, old newspapers and silica were used to make natural fiber cement boards for the building partition. Experimental results show that the unit weight of natural fiber cement boards are about 1408 to 1630 kg/m³. The flexural strength of natural fiber cement boards is 70% higher than that of typical building materials and thermal conductivity with 0.217 to 0.430 Watt/m°K shows a good combustion-resistant capability.

Keywords: Rice husk, old newspaper, silica, cement, poly vinyl astate, poly ol.
