Use of Recycled Brick in Aggregates

Conservation and reuse of resources is a necessity in achieving sustainability across the globe. In recent years, construction and demolition debris including bricks has appeared in stockpiles around Minnesota. The objective of this research project was to investigate the possibility of putting the brick to beneficial use as aggregates for base courses in pavements. This would help to conserve natural stone aggregate and also recycle the brick instead of dumping it as waste in a landfill. In addition, contractors could save money by being able to reuse locally available material. MnDOT is already quite progressive in its use of recycled materials and allows the use of recycled concrete aggregates, recycled asphalt pavement, and recycled glass in base and surface courses. Based on current literature review, Minnesota may become a pioneer in the use of recycled brick aggregate as well. There are many different types of clay bricks including structural bricks (both commercial and residential), pavers, and refractory bricks. The structural bricks and pavers will also vary from region to region. The bricks used in Minnesota are of the highest quality available because they have to meet severe weathering requirements. Structural brick accounts for the largest amount of brick manufactured. In this project, samples of various types of bricks were tested. The main tests conducted were the Los Angeles Rattler to assess abrasion properties and the magnesium sulfate soundness to evaluate freeze-thaw durability. In addition, basic engineering properties such as specific gravity and absorption were determined.
