Does Sand Affect Brick Durability?

Does Sand Affect Brick Durability? | Science Fair Projects | STEM Projects
In this project, you'll mix clay, sand, and water to make bricks, then test how many times they can be dropped before they break.


The hypothesis is that coarse sand particles make more durable bricks than fine sand particles.

Method & Materials

You will label wooden frames, coat them with grease, mix clay, sand, and water, pour the mixture into the frames, dry the frames, separate the bricks, label them, and place them in an oven.
You will need wooden frames, clay, fine sand, coarse sand, tap water, empty pails, a chair, a measuring tape, an oven, a black marker pen, and grease.


The results showed that the brick made from coarse sand was more durable than the brick made from fine sand. The brick made from coarse sand lasted an average of 2.6 drops while the brick made from fine sand only lasted an average of 1.6 drops.

Why do this project?

This science project is interesting because it shows how the type of sand used to make bricks can affect their durability.

Also Consider

Variations of this project could include testing different ratios of materials used to make the bricks or testing how much compression or weight the bricks are able to bear.
