The Manufacturing of Cement (and Concrete??)

Our recently posted article…., linked below, got wondering about the origins of cement, so I turned to my old friend, the book Dictionary of Industrial Archaeology by William Jones.

Thanks to SCT for proofreading my retyped extract from the original book.

Cement a calcinated mixture of lime and clay ground into a powder which, when the correct amount of water is added, is used for joining building materials together, or for making concrete. It is applied as a stiff paste between stones or bricks, and when set (i.e. hardened) it has an adhesive power bonding the items together. Hard cement is strong in compression, but weak in tension, hence its usefulness in foundation work.
