Effect of Silica Fume on Durability of Wood Fiber Reinforced External Wall Board

Abstract:

In order to improve the durability of the wood fiber reinforced external wall board, silica fume, a kind of inorganic silica material was added in the board. The properties of the boards containing different amount of silica fume were studied. The durability was effectively characterized by determining the fracture work and bending strength after wetting-drying cycles test of the board. The results showed that the fracture work and bending strength of the board obviously increased when the proportion of silica fume and cement was 1:9~1:3.
