For massive engineering works, such as breakwaters, docks, and sea-walls, and for the foundations of structures great or small, concrete has been largely used, but for the walls of ordinary houses it has not found much favour. A causes have combined to hinder architects from adopting it. Notably among these are the dangers arising from its manufacture by careless workmen and unscrupulous contractors, the difficulty and expense of moulding it to curved and irregular forma, and the bald appearance and unlovely colour of the material itself.

Other objections to concrete walls are their homogeneity and hardness, which render the hanging of pictures and the fixing of plugs difficult tasks, and which make alterations a costly affair (this last is raised as an objection sometimes, but may perhaps be regarded as an advantage). The ease with which sound is transmitted through concrete walls is certainly a point against them. But it may be said, on the contrary, that good concrete is considerably less pervious than brickwork and some kinds of stone, stronger and more durable, and, under certain circumstances, cheaper."1
