Does the type of sand affect the durability of bricks Featured science projectScience project video


What makes some bricks stronger than others? This science fair project aims to compare the effect of sand particle size on brick durability.


Coarse sand particles make more durable  bricks  than  fine sand particles.

Scientific Terms

Bricks, mortar, corrosive, fire resistant, kiln



Bricks are ceramic blocks that are made from clay, sand and water. They are used in construction for building walls and pavements. The bricks are normally secured using mortar while they are being arranged in rows and/or stacked up. Mortar is a mixture of cement, sand and water.

Bricks are normally small in size. This makes it  convenient for  brick layers to work with them. It also  enables  construction work to be carried out in small and confined spaces
Bricks are  durable and require very little maintenance. They are also non corrosive and are fire resistant

Bricks continue to have a very important place in the construction industry, despite being invented centuries ago.
