The paper concerns investigation of the effect of impact crusher operation on selected qualitative characteristics of mineral aggregate products. Qualitative characteristics of crushing products in terms of size reduction ratio and fine particles contents were analyzed from the point of view of operational parameters of the impact An option to prevent waste from going to dump sites is the conversion of RC into recycled aggregate (RA), which usually requires crushing and sieving. This alternative is interesting, because it converts most of the incoming waste into product and does not require water in the process, as the aggregates are produced by washing non-hardened Evaluation of the use of crushed returned concrete as

Crushing Characteristics of Coarse Aggregates for Asphalt

The aggregate crushing mechanism was found to be controlled by the fracture mode; the contribution of the attrition and abrasion modes was relatively small. When coarse aggregates with low crushing resistance are considered for the use for asphalt mixture, proper compaction is proved to be vital to prevent excessive aggregate The effect of coarse aggregate crushing on the mechanical properties of normal concrete and high-strength concrete during the uniaxial compression test is investigated.
