The tests for Aggregate Crushing Value (ACV) and FACT (10% Fines Aggregate Crushing Test) measure the crushing strength of broken rock. These results do not necessarily relate to the ﬂexural or compressive strength of concrete made with that aggregate, but are a useful index of overall quality. Normal values for ACV range from 14 to 30%, and for
Jun 30, 2011 · For the purpose of this article the term crushed concrete aggregate (CCA) is defined as returned concrete and recycled concrete aggregate clean enough to be used as aggregate for new concrete. Recycled concrete aggregate (RCA) refers to crushed concrete and other materials suitable for use as fill and compactible fill.

Concrete Mix Design Definition Concrete mix design is defined as the appropriate selection and proportioning of constituents to produce a concrete with predefined characteristics in the fresh and hardened states. In general, concrete mixes are designed in order to achieve a defined workability, strength and durability .
gate, such as gravel, requires slightly lower values, while crushed aggregate requires slightly higher values. Fine aggregate content is usually 35% to 45% by mass or volume of the total aggregate content. CHARACTERISTICS OF AGGREGATES. The important characteristics of aggregates for concrete are values Bulk density Mix design calculations
