Aggregate (composite) - Wikipedia

Aggregate is the component of a composite material that resists compressive stress and provides bulk to the composite material. For efficient filling, aggregate should be much smaller than the finished item, but have a wide variety of sizes. For example, the particles of stone used to make concrete typically include both sand.

Polished Concrete Aggregate Exposure Chart - American Society of .

Aggregate exposure class denotes the surface exposure after grinding and polishing operations. The density, size and distribution of the aggregates at the surface depends on the concrete mix design and placing and fin- ishing operations. Floor flatness at the time of grinding and polishing operations is an important.

The Specification of Honed or Polished Concrete Finishes - CCAA

1. Description anD scope. Honing gives concrete a smooth matt finish by grinding the concrete surface and exposing the aggregates. Smoother (polished) concrete surfaces can be achieved through extended honing using progressively finer abrasives (finer grinding grit heads/pads) to impart a lustre to the concrete surface.

Aggregates for Concrete - Civil Engineering

coarse aggregates generally occupy 60% to 75% of the concrete volume (70% to 85% by mass) and strongly influ- ence the concrete's freshly mixed and hardened proper- ties, mixture proportions, and economy. Fine aggregates. (Fig. 5-1) generally consist of natural sand or crushed stone with most particles smaller than 5.
