One area of the concrete life cycle worth noting is the fact that concrete has a very low embodied energy relative to the quantity that is used. This is primarily the result of the fact that the materials used in concrete construction, such as aggregates, pozzolansand water, are relatively plentiful and can often be drawn from local sources. With a total embodied energy of 1.

Various forms of chamber kiln rose to dominance in the s. Less obvious here is the arrival of continuous kilns from onwards: the latter had times the output of batch kilns.
