A Greenhouse Study of Concrete Grinding Residue Influences on Seedling Emergence and Early Growth of Selected Prairie Species . Abstract . Concrete grinding residue CGR is a byproduct of diamond grinding, a road surface maintenance technique. Direct deposition of CGR along roadsides may influence plant growth, which has not been fully studied.
In this paper we present a study on the effect of chemical grinding aids during cement grinding. Cement samples produced with and without grinding aid are compared in terms of performances and milling efficiency. Microscopy techniques are used to confirm and understand the reasons for the variations in grinding efficiency and for the ...
