Abstract
Chemical, mineralogical and physical characterization of nine Canadian brickmaking raw materials, as well as the general physical properties of the corresponding burnt samples from the brick plants and the laboratory firing, are studied. Possible relationships between the properties of the raw material and the burnt brick are discussed. All the raw materials contained illites mixed with chlorites. The geological formation of the shales seems to determine the relationships between free quartz and total silica, and between free quartz and calcium carbonate. Within the normal brick-firing temperature range, the water absorption of the burnt brick is a function of the calcium carbonate content and the forming technique. The saturation coefficient seems proportional to the amount of fine particles in the green bricks and inversely proportional to the coarse fraction. All laboratory-fitted samples, except one type, show absorption characteristics similar to the plant-burnt bricks.
