Tensile Testing Essay
Question 1: Compare and contrast the use of timber frame with concrete frame in construction, clearly comparing the use of each material by their individual characteristics and properties, advantages and disadvantages, costs, durability, climatic resistance and ease of assembly and adaptation.
Concrete is “a building material made from a mixture of broken stone or gravel, sand, cement, and water, which can be spread or poured into moulds and forms a stone-like mass on hardening” (http:// (www.oxforddictionaries.com/definition/english/concrete)
Timber is described “as wood prepared for use in building and carpentry” (http://oxforddictionaries.com/definition/english/timber).
Concrete is known to be one of the …show more content…
The climate usually affects the ground conditions of the site as well; there can also have a massive impact on the selection of what material to use for constructing a frame. The foundations for a timber frame house have to be very accurate to place the frame on top. There is very little room for movement or changes. However with insitu-concrete, the design can be changed up to the last minute and alterations are easily made if the foundations are inaccurate.
Many timber frames are built off site, therefore are less labour intensive, with only a general need for carpenters onsite during installation, and extremely quick to erect. Reinforced concrete frames are built up onsite. They are very labour-intensive, with multiple trades having to work onsite at any one time, and the programme of works is generally a lot longer as the workers onsite have to wait for the concrete to cure. Because the timber frame e is built off site, there doesn’t need to be as much storage space onsite. This can be a massive factor, depending on the area you have got to work in, and can be an impeding factor on what frame you decide to use to construct your frame. There is also likely to be more downtime onsite with a concrete frame, due to not being able to our concrete in the rain. The addition of extra water to a concrete mix can weaken
