Aggregate properties significantly affect the workability of ...
What is a Jaw Crusher? – MEKA Crushing Equipment
In general, crushing is carried out in three stages, depending on the desired size of the material. Primary Crushing. This is the first stage of the crushing process. In general, the size of the feed material, which is between 800 and 1500 mm, is reduced to between 150 and 300 mm. Secondary Crushing. This is the second stage of crushing.

A Practical Guide to Grouting - Parchem
Looking first at cement based grouts, these materials are essentially fine concretes - cement, aggregate and admixtures in a bag - to which we add water on site. Concrete shrinks - so does a cement based grout. What we need to do is minimise or compensate for this shrinkage, hence the term "Shrinkage Compensation".

Crushing Plant - an overview | ScienceDirect Topics
The crushing process produces agglomerations of the original concrete's aggregates with adhered mortar. These agglomerations are, typically, more angular than conventional aggregates. Also the crushed concrete will produce fines from the mortar element, the amount being controlled to a large extent by the strength of the original concrete.
