4.1.1.2 Crushed rock aggregates Crushed aggregate is quarried or excavated stone that has been crushed and screened to the desired standard particle size and distribution. The particles of crushed aggregate are completely crushed. This gives the products good compaction and load-bearing properties.

Ten materials were selected (Table 1), five crushed aggregates from Sweden, three natural sands from Iceland and a CEN-Normsand (DIN EN 196-1) as reference material. Additionally, a crushed aggregate from Brazil, which is presently used in concrete production was also analysed. Six of these samples were also included in the grain-size …

However, the increase is not very evident. Permeability of crushed RCA concrete is shown in Figure 19 a–c. Permeability of concrete containing 25% rounded RCA replacement of coarse aggregate is similar to reference sample as well. Increase of rounded RCA content to 50 and 75% leads to evident increase of permeability.

Aggregate size and shape measurement is comparatively difficult but has a larger impact on concrete properties. Four methods are available to estimate the size and shape characteristics of particles. The accuracy of each method depends on the particle sizes. Aggregate size varies from 0.15 to 25 mm for normal concrete.
