MAKING BRICKS WITHOUT CLAY. technical l innovation in the Junction 1905 Machinery

MAKING BRICKS WITHOUT CLAY. An industry is about to be established in Toronto Junction which may have a very important bearing upon the building operations of the city in the near future. A company is being formed to manufacture what is called ” silica brick ” with the ” Berg ” press on the sand lime process. The brick is, in short, nothing but sand, with from S to 10 oer cent, of lime mixed, pressed under heavy pressure, steamed over night, and is ready to put in a wall next day.

The brick, which can be made from ordinary sand is somewhat whitish in color.
A brick made from the sand pits at Toronto Junction has been tested at the School of Science and supports a pressure of 1-2 tons.
