Concrete bricks can be produced in a variety of forms, colours and sizes, at costs very competitive with traditional clay brick but with substantial advantages. Because concrete bricks have higher strength, reliable dimensional accuracy, require minimal maintenance, and can be made in a wide variety of shapes and colours, they are a very lucrative part of the manufacturer's product line. Columbia Machines are extensively used for the manufacture of flyash bricks. Cement consumption of flyash bricks, made on a Columbia machine, is much lower than the cement consumption on German flyash brick making machines or a China (Chinese) flyash brick making machines or Coimbatore flyash brick making machines.
