anchorConcrete is a mix of large aggregate, small aggregate, and cement (a 4:2:1 ratio is a good approximation though designed mixes will be more calculated than that). The size of the large aggregate isn't particularly important, unless you are working in very tight spaces or around reinforcement, in which case you want suitably small aggregate. In this case there won't be a .
White Cement Concrete and Colored Concrete ConstructionSpecifiion for Concrete Aggregates should be followed to limit impurities in aggregates. Coarse aggregates should be free from iron oxides and other minerals that can stain the concrete matrix. Aggregates should not contain injurious amounts of organic impurities.

CIVL 1101Aggregates generally occupy 70 to 80% of the volume of concrete and therefore have a significant effect on its properties. Strength of concrete and mix design are independent of the composition of aggregate, but durability may be affected. Aggregates are classified based on specific gravity as heavyweight, normalweight, and lightweight. Normal weight aggregates makeup 90% of concrete .
Ways to Recycle and Reuse Concrete · Aggregate for mixing new concrete: Crushed concrete can replace some of the (new) aggregate used in readymix concrete. Controlling streambank erosion: Larger pieces of crushed concrete placed along vulnerable stream banks or gullies can help control erosion.

They may also have great deals for you. A ballast is a mixed aggregate which contains small stones and sharp (or grit) sand.
Judging Aggregate Reactions in Concrete| Concrete ... · The swelling, in turn, creates pressures inside the concrete that, if high enough, will cause cracking. The best method to avoid ASR is examining structures that are at least 20 years old and made with the aggregate you wish to use. A careful visual examination should reveal if there is evidence of ASR. If you cannot examine structures in the field and lack service records for aggregates ...
