Crushed Stone an overview ScienceDirect Topics

Tests have also shown that steel slag is an equally good substitute for gravel or crushed stone aggregate in both stabilised cement and unbound base layers. Properties of a cementstabilised mixture of slag, natural crushed stone, and 0.7% and 2% of cement (Class 42.5 N) meet the compressive strength criteria set by Croatian standards [27].

Aggregate Crushing Value Test Determine Aggregate

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
