    Technically Speaking: FineTuning Concrete's Volume

    About 60% to 75% of concrete's volume is comprised of aggregates (both fine and coarse aggregates). Fine aggregates typically consist of sands or certain types of crushed stone, with most particles being smaller than 5mm. Coarse aggregates are usually made of gravel, crushed stone or a mix of both.

  • Crushed Concrete Aggregates

    Crushed Concrete Aggregates

    By and large, strength of concrete produced from crushed concrete aggregate is lower than concrete made using natural aggregate. Strength reduction of concrete produced from recycled coarse aggregate and natural fine aggregate ranges from 5 to 24%. This influenced by strength of crushed concrete, water to cement ratio of crushed and new concrete.

    Jun 30, 2011 · Recycled concrete aggregate (RCA) refers to crushed concrete and other materials suitable for use as fill and compactible fill. Initiatives to use CCA in concrete mixes have proceeded slowly and cautiously for many reasons. A central concern is whether CCA can have the same quality as materials—a pile of demolished concrete could have ...
