Concrete grinding residue (CGR) is a slurry waste consisting of water and concrete fines generated from diamond grinding operations that is used to smooth a concrete pavement surface. During this process, CGRs are mostly disposed along the roadside, which can influence soils and plant communities along the roadways.


In the road construction industry, when diamond grinding concrete highways, water used to cool cutting blades combines with hardened cement paste and aggregate particulates. This byproduct, concrete grinding residue (CGR), is commonly called slurry. How CGR is handled varies greatly across the country.

concrete, which is a combination of cement, mineral aggregates and water. Concrete is a key building material for a variety of applications. The U.S. cement industry is made up of either Portland cement plants that produce clinker and grind it to make finished cement, or clinker-grinding plants that intergrind clinker


Finish grinding of clinker and other cement ingredients reduces 25 mm clinker balls to particle sizes optimally ranging from 3 to 30 microns. The European Cement Research Academy (ECRA) estimates that up to 70% of the power consumed in cement production is for material size reduction. Increasing the efficiency of particle size reduction could
