The least immediate expense is incurred by spreading CGR slurry directly on vegetated roadway ditches and …
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. Particularly, systematic experiments of CGR effects on selected common prairie species growth under controlled environments are rarely reported. …

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 … Expand. 2. PDF. Save. Alert. Research Feed. Effects of concrete grinding residue (CGR) on selected sandy loam properties.
An area of focus within the construction industry throughout the past few years has been the question of how to handle concrete grinding residue (CGR), also known as sawing slurry. Generated during sawing and diamond grinding operations, slurry is the byproduct created when a diamond blade's cooling water mixes with concrete fines.
Concrete slurry is generated when activities such as concrete diamond grinding or saw cutting occur as associated with the construction, repair or improvement of roads. ... with each pass of the grinder moving the spreading operation farther down the in-slope to ensure no build-up of grinding residue.

That means that if you clean up right after grinding, there could still be particle residue a few hours later once it has settled. Final Thoughts. Concrete dust can be dangerous to humans and pets, particularly with prolonged exposure. That is why it is important to clean it up as soon as possible.
Concrete diamond-grinding on. pavement projects generates a non-hazardous waste byproduct called concrete grinding residue. (or CGR). CGR has known cementitious characteristics that suggest a latent use as a soilstabilizing. amendment, especially for poor and problematic soils.
As part of the diamond grinding process, water used to cool cutting blades combines with hardened cement paste and aggregate particulates, creating a byproduct is known as concrete grinding residue...
Interpretive Summary: Concrete grinding residue (CGR) is a slurry byproduct created by concrete pavement maintenance operations. The material is characteristically high in calcium. The application of CGR to roadside soils is not consistently …
2. The equipment for grinding cement concrete pavement shall use diamond embedded saw blades gang mounted on a self propelled machine that is specifically designed to smooth and texture concrete pavement. The equipment shall not damage the underlying surface, cause fracture, or spalling of any joints. 5-01.3(2) Material Acceptance
As a precautionary principle, the National Pollutant Discharge Elimination System (NPDES) permit establishes that the primary pollutant in concrete grinding residue (CGR) is its alkalinity and restricts CGR roadside discharge to 11 Mg ha −1 or the agronomic rate, whichever is lower. We evaluated the effect of CGR application on roadside soil chemical …
Concrete grinding residue (CGR), or "slurry," is a byproduct of diamond grinding concrete highways. It is made up of water used to cool blades, hardened cement paste and aggregate particulates. Is Slurry a Problem? Many states limit how much slurry can be discharged along the roadside during the diamond grinding process.
Concrete grinding residue (CGR) is a by-product created by concrete pavement maintenance operations. The application of CGR to roadside soils is not consistently regulated by state agencies across the USA, which is partially due to the lack of science-based information on its impacts to soils and plants. The objectives of this research were to …
At concrete pavement grinding sites, slurries of grinding dust and cleaning water are collected in tankers before disposal. Often the slurry is sprayed or dumped on roadside vegetation. "Concrete grinding residue or slurry can, under certain conditions, be a benefit. It can act as a agent, changing soil pH in a positive manner."
Typically, this operation uses a truck equipped with grinding heads at ground level to saw a thin layer of concrete, grinding it into fine particles, while mixing with water to cool blades and reduce dust. This process generates a slurry byproduct known as concrete grinding residue (CGR). The majority of current maintenance practice involves ...

Diamond grinding is a concrete pavement maintenance technique, and concrete grinding residue (CGR) is the byproduct. Concrete grinding residue deposited along roadsides affects soil chemical properties, but impacts of CGR on soil physical properties and plant growth are rarely studied.
Concrete road repairs often require the contractor and engineer to develop a plan to manage the residue generated during sawing and diamond grinding operations, known as sawing slurry or concrete grinding residue (CGR). …

The Husqvarna PG 400 Floor grinder for surface preparation and grinding of adhesive residue, paint and epoxy on large concrete areas. The grinding and suction is efficient thanks to the high rpm levels, the wide range of grinding discs and the design of the dust guard and vacuumport. PG 400 is easy and convenient to use, with ergonomically designed handlebar and low noise …
Summary: This MnDOT study determined that depositing concrete grinding residue (CGR) slurry at specific rates on roadside vegetation and soil may not cause lasting harm to plant growth and soil quality. Study results showed that CGR did not appear to hinder vegetation growth or soil quality, but did change soil chemistry.
Diamond grinding is a concrete pavement restoration technique that corrects irregularities such as faulting and roughness on old concrete pavements and extends the life of pavement. Cooling water used during the diamond grinding of concrete pavement highways generates slurry consisting of water, concrete and aggregate residue (CGR).
