Urban wastes recycling into fired clay bricks: A review

rick is one of the most common masonry units used as
building material. Due to the demand, different types of
waste have been investigated to be incorporated into fired clay
brick for example sludge wastes, agricultural wastes, fly ash,
fuel wastes and other wastes. Previous investigations have
demonstrated positive effects on the physical and mechanical
properties such as lightweight bricks with improved shrinkage,
porosity and strength. However, reduced performances in
number of cases were also demonstrated. In addition, the
high temperature in the firing process allows volatilization
of dangerous components through emissions, changes the
chemical characteristics of the material and eliminates the
toxic components through fixation process. Therefore, this
alternative disposal method for the urban waste may provide
sustainable method to immobilise toxic chemicals that pose
a very high risk to the environment through either leaching
or emissions as well as providing a new construction product
with improved properties providing the mix is appropriately
designed and prepared for the required properties.
