How Aggregate Shape Affects Concrete Bond

Aggregate shape and surface texture affect how well concrete holds together. Rough, angular aggregates usually bond more strongly with the cement matrix than smooth, rounded ones. This stronger adhesion can help produce high-strength concrete.

Angular aggregates also have a larger surface area. T...

The strength of a concrete mix made of rough and angular aggregates is higher than that of smooth and rounded aggregates.

This is because a rough surface offers better bonding with cement particles than a smooth surface.

Additionally, compared to round aggregates, angular aggregates offer a larger surface area to adhere to for ceme...
