The replacement of timber products by nonrenewable materials is an unfortunate development, since it has been repeatedly shown that the use of timber does have associated environmental benefits compared with the use of nonrenewables (e.g. Marcea and Lau, 1992 Hillier and Murphy, 2000 Bowyer etal., 2003 Lippke etal., 2004). Timber has a lower embodied energy content (and hence a more favourable carbon emission profile) compared to most other building materials and can provide other benefits, such as improved thermal properties. It and the products made from it (in common with other renewable materials) can be used as a repository for atmospheric carbon dioxide. Wood is derived from a renewable resource, albeit potentially an exhaustible one unless it is managed correctly. Disposal of wood can be readily achieved with little environmental impact (subject to how the wood has been treated prior to disposal). 

In front of the building a timber floor protected by a eave should be laid. Trucks coming and going with materials should be moved by hand. Trucks with pneumatic-tyred wheels or barrows with bronze wheels are best for this purpose. If a narrow-gauged track is to be used, in the vicinity of buildings holding blackpowder, the rails should be of wood and the trucks should be fitted with bronze wheels. 

This paper deals with the reuse of used timber as wood-chip concrete which is made by injecting cement paste into the void of compacted wood-chip. It will be finding that a valuable building material could be made by the method developed by the authors. 

Wood treated with copper arsenate (CCA timber or Tanalith) is used as a structural and outdoor building material.

Are standards (uprights) resting on suitable base plates and (where the scaffolding is not on hard standing) timber sole boards Bricks, blocks and other building materials should not be used as packing. 

Building materials with high fire resistance are, for example, brick, stone, concrete, very heavy timbers (the outside chars and insulates the inside of the timber), and some specially made composite materials used for fire doors. 

The primitive savage endeavors of mankind to secure protection against the elements and from attack included seeking shelter in rock caves, learning how to build tents of bark, skins, turfs, or brushwood and huts of wattle and daub. Some of such types crystallized into houses of stone, clay, or timber. The evolution of mankind is thus linked to the history of building materials.

Autotrophic vegetation as a whole has rendered possible the development of animals on earth, of consumers and predators at the higher levels in the food chains of ecosystems. More than 100,000 species of animals, most of them insects, depend on the producers life. Mankind cannot survive without green plants and their capability of building up carbohydrates from just water and carbon dioxide in the chloroplasts of leaves by the use of solar energy. Agriculture and horticulture have made use of this capacity since prehistoric ages and forestry has developed from the uncontrolled use of firewood and timber for houses, ships> tools, and furniture to a planned production of renewable raw materials.
