High-strength concrete containing basalt and normal-strength concrete containing basalt or limestone yield higher compressive strengths with higher coarse aggregate contents than with lower coarse aggregate contents. The compressive strength of high-strength concrete containing limestone is not affected by aggregate content.

Exposed Aggregate Concrete - Decorative Pebble Finish ...

An exposed-aggregate surface is obtained by placing concrete and then removing the outer 'skin' of cement paste to uncover decorative coarse aggregate (either batched into the concrete mix or seeded onto the surface). Because of its durability and skid resistance, an exposed aggregate finish is ideal for most flatwork including: Sidewalks.
