Researchers used a computer method to study how concrete breaks at a small scale. They found that the type and direction of rocks in the concrete affect how strong it is. More glue between rocks makes concrete weaker. Concrete breaks in a certain way, with cracks forming around the glue. The shape of the concrete also affects how it breaks. Notches in the concrete change how it breaks too.
