Considerations Before Using Nanomaterials in Construction

Considerations Before Using Nanomaterials in Construction

Oct 16, 2020 More confounding is that even if you don’t add nanomaterials in concrete, it may release them when demolished. In fact, cutting, grinding, sanding or spraying may all produce dust or mist that could get inhaled, ingested or absorbed. To evaluate the risk, you need to determine worker exposure and dose, but that research can be complex.
