Abstract
In this work fibers of dry reed was used a reinforcing material to produce cement boards after being chemically treated in order to enhance the bonding between mortar and fiber and prevent the dissociation of the composite material with time. (2%,4%,6%,8%) percentages of reed fiber was mixed for every Reed fiber size (300μ,150μ,75μ)
The curing period was 14 days, physical and mechanical tests were performed according to ASTM standard c-1185.
Different variation in results observed by changing fiber content and fiber size. The results showed an enhancement in density, thermal insulation, by increasing reed fiber content and decreasing in size, while its shows an increasing in moisture content and water absorption by increasing reed content because reed is one type of soft wood, the wood property is absorbing and keeping moisture. The best dry and wet flexural strength is in 8 wt% of 150μ reed fiber.
