Cultural preference is another important factors since it indicated the acceptance of the products as alternative construction material. House formed out of concrete are the preffered type in this country. Most house in the urban and suburban areas are shanties made of bamboo or wood. Concrete dwellings can therefore be regarded as a status symbol because of it being cementitious in nature. WWCB have popular in the Philippines as an alternative to concrete, and it has proven to withstand adverse effects of tropical cyclones, seasonal monsoon rains, and high humidity, WWCB have the required strength as well as the resistance to high humidity in the tropical climate as presented in table 2.1.
Aside from the excellent dimensional stability and acceptable mechanical properties of wood wool cement board, it also has some degree of resistance against combustion and attack by termites and micro-organisms, such as fungi and decay. It is the presence of cement particles in the wood cell wall that provide that resistance against micro-organisms and reduces combustibility (Parmaswerran, 1977).

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONE BACKGROUND TO THE STUDY1.0 INTRODUCTIONRight from when man stated to build, he has been compelled to use the locally available materials around him. Building has now become major construction material allover the world has necessitated a critical study of its constituent materials. More so, the present economic crunch calls for cost saving measures on the part of engineers/researchers involved in the management of the country’s project.Hence, the need for researchers to ...

CHAPTER THREE - [ Total Page(s): 1 ]CHAPTER THREEMETHODOLOGY3.1 INTRODUCTION The production of the cubes involves the construction wooden moulds, acquisition of materials, mixing of the cube materials, pressing and curing. A laboratory test on the physical and mechanical properties of the cube is carried out.3.2 MATERIALS PROCUREMENT The wood planks used were procured from the sawmill at Irewolede and it is commonly known as Omo wood (Alstonia Longesis). The wood planks were cut into thinner planks with a m ... Continue reading---
