Abstract

Taiwan is situated in the seismic belt and belongs to the subtropical climate. The abilities of heat insulation and seismic resistant of buildings in Taiwan were become more and more important. Fundamentally, it should develop a new materials suitable for use in hot and humid environment. This research aims to study the engineering properties of the wood-wool cement and compare with those of traditional building materials. The test results show that the unit weight of wood-wool cement boards is about 615 kg/m3. The wood-wool cement boards collocate with the light-weight rigid frame and paste those construct the wood-wool cement light wall, its unit weight will increase to about 1580 kg/m3; Compare with the unit weight 2300 kg/m3 concrete, the unit weight of wood-wool cement boards and light wall will decrease 73% and 31%, respectively. The wood-wool cement light wall is not only beneficial to convenience of construction but also increase the load-bearing capacity of buildings, future more, it is contribute to reduce the seismic force. The thermal conductivity of wood-wool cement boards and the wood-wool cement light wall are about 0.09 kcal/m-hr-°C and 0.58 kcal/m-hr-°C, which compare with the test result, 1.25 kcal/m-hr-°C of concrete with compressive strength 210 kg/cm2 are obviously decrease. As bending strength and wind pressure test that we know, the wood-wool cement light wall is worse than reinforced concrete. But the mechanics of the wood-wool cement light wall corresponds to the wallboard strength requirement of Taiwan Building Code. From the economic analysis, the wood-wool cement boards possess higher economic benefits due to better energy efficiency. As we know from the above, it can be expected soon to use the wood-wool cement light wall in buildings.
