Wood is organic, natural, and is a product of trees. Most woods are brown; however, some are lighter in color. Wood is an accumulation of cellulose with the fibers intact, which makes it firm and resistant to outside forces. Wood is used for many purposes other than furniture. It is used for providing fuel, packaging, and even for producing paper.
Concrete is made of cement and other building ingredients such as water and sand, among others. It is one of the most regularly used building materials. When aggregate is mixed with dry cement and water, the mixture forms a fluid substance that is easily poured and formed into shape.
The way concrete is handled after it is poured is particularly important. Unlike wood, the concrete material hardens after the water has been mixed and endured the hydration process.
