5 Things I Learned When Grinding Concrete for the First Time
21.08.2017· Using a concrete grinder is something that I always wanted to do when I started working at Bartell Global. A friend of mine needed a hand removing some glue off of a floor and I thought, hey this can’t be so hard, let’s give it a go! I knew the theory of concrete grinding pretty well, so I thought I was pretty prepared after talking to some of our grinding experts. The short version of
Concrete grinding, Practice of grinding, Health and safety
Concrete grinding produces silica dust. If the dust is breathed in over a period of time, it can lead to a disease called silicosis or scarring of the lungs. This was such a common problem for grinder operators in years past that one of its common names was 'grinder's asthma'. Audio for slide 13 (mp3 |6|KB) Fortunately, most modern machines have very good dust extraction systems. Depending on

LITERATURE REVIEW CONCRETE GRINDING RESIDUE DISPOSAL
Concrete grinding residue (CGR) is a slurry byproduct created from diamond grinding operations that is used to smooth concrete pavement surface. As a waste material, CGR consists of cooling water for grinding blades and concrete fines from the removed concrete layer. Since the CGR has high pH, it can be a critical environmental issue and should be managed properly to reduce its impact to the
