Demolition and recycling - Options for recycled brick material

Aggregates for calcium silicate bricks

Crushed clay bricks, tiles and other masonry can also be used as aggregate in cast concrete. The crushed material replaces other raw materials such as sand and causes fewer disturbances to the landscape.

The production of crushed masonry aggregates for concrete involves crushing, sorting and cleaning the demolition waste.

The main environmental impact of this process is the production of dust during crushing and sieving. The problem can be minimised by sprinkling with water and is comparable to problems connected with the production of natural aggregates.

Several European research projects have explored the potential of using crushed masonry as aggregate for concrete. It is common practice in Austria, Switzerland, Denmark and especially Holland.
