Feb 01, 2019· 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…

Apr 15, 2017· A recent study showed that the properties of recycled concrete aggregates (RCAs) can be significantly improved by acetic acid treatment. This study demonstrates that a useful product, vaterite, a metastable polymorph of calcium carbonate, can be produced from the waste solution of this treatment through an improved pH swing method.

Effect of Acetic Acid on Concrete. Concrete in use in agricultural applications may be attacked by the silage effluents containing mainly acetic and lactic acid. Acetic acid reacts with cement hydration products to form calcium acetate. 2CH 3 COOH + Ca(OH) 2 ==> Ca(CH 3 COO) 2 + 2H 2 O. 2CH 3 COOH + C-S-H ==> SiO 2 + Ca(CH 3 COO) 2 + 2H 2 O

Hydraulic cements such as Portland cement are interground with diesters formed by reacting a polyol (e.g. alkylene glycol) with a monobasic carboxylic acid (e.g. acetic acid) to enhance the efficiency of the grinding operation.

Degradation of cement

Continue applying the acetic acid and scrubbing the cement until all calcium deposits are removed. Step 5 Sprinkle baking soda liberally over the clean cement to neutralize the acid. While the acid neutralizes, fill a plastic pail with water.
