acetic acid cement grinding

The anomalous solidification of concrete grindings from ...

By studying the 13 C and 29 Si SSNMR spectra, as well as the PXRD patterns of the concrete grinding residue and the solidification product, it was determined that the citric acid treatment leads to the extraction of the calcium from the concrete framework. This in turn enables the solubilization of the 1D silica chains found in concrete, which ...
