Concrete Sludge Brick is made of concrete sludge and small amount of cement. The use of concrete sludge can reduce usage of sand in bricks production and at the same time reduce the production cost. This also can help in protecting the environment in the long run by reducing sand mining activities.
Concrete Sludge Brick produce a comparable compressive strength to normal sand brick but with cheaper production cost. The production cost is approximately 30% lower compared to the normal sand brick. In term of density, Concrete Sludge Brick exhibit lower density compared to normal sand brick thus offer better handling on the site
