Acetic Acid is a synthetic carboxylic acid with antibacterial and antifungal properties. Although its mechanism of action is not fully known, undissociated acetic acid may enhance lipid solubility allowing increased fatty acid accumulation on the cell membrane or in other cell wall structures.
These included the use of acetic acid patented by Missouri Portland cement with C 465 approval gained by Union Carbide, HEA2™ by W. R. Grace, and REAX by Westvaco. Later, various glycols came into use as grinding aids, with products being marketed by numerous companies such as Dow, Union Carbide, Westvaco, and W. R. Grace.
Grinding aids for hydraulic cement Dec 2, 1985 W. R. Grace Co. Hydraulic cements such as Portland cement are interground with diesters formed by reacting a polyol ( alkylene glycol) with a monobasic carboxylic acid ( acetic acid) to enhance the efficiency of the grinding .

CNB Acetic acid triethanolamine ester as well . The invention also discloses an application of the acetic acid triethanolamine ester as a cement grinding assistance reinforcing agent in the grinding production of cement, and the adding amount ofthe acetic acid triethanolamine ester is percent of the total weight of the cement.
Acetic acid also forms miscible mixtures with hexane chloroform and several oils However it does not form miscible mixtures with longchain alkanes (such as octane) The desirable solvent properties of acetic acid along with its ability to form miscible mixtures with both polar and nonpolar compounds make it a very important industrial

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 + CSH ==> SiO 2 + Ca(CH 3 COO) 2 + 2H 2 O
The acetic acid is used for the manufacture of grinding admixtures in the cement industry. The most admixtures used by commercial milling are mixtures of amine acetates, glycols and sugars. The commercial formulations contain 10% acetic acid as amine acetate. In this work the amine acetate was synthesized using the product from fermentation of ...

They include 1,2propanediol, acetic acid, triethanolamine and lignosulfonates. Temperature control Edit Heat generated in the grinding process causes gypsum (CaSO 4 .2H 2 O) to lose water, forming bassanite (CaSO 4 . 2 O) or γanhydrite (CaSO 4 .~ 2 O).
A process for increasing the grinding efficiency of Portland cement and for inhibiting the pack set of said cement which comprises, intergrinding with said cement from to percent by weight of cement of an additive consisting essentially of, a watersoluble glycol and a watersoluble salt of an aliphatic acid having less than three ...
Dec 08, 1987· The present invention is based upon the discovery that diesters formed by reacting a polyol, mono and polyalkyl diols and ls with a monobasic carboxylic acid, acetic acid, are excellent grinding aids in the grinding of hydraulic cements such as Portland cement.
Grinding aids such as glycol, amines, and acetic acid help cement particles to flow efficiently. This reduces grinding energy and results in increasing product throughput. These grinding aids are added to the cement prior to the final grinding circuit.
on cement matrices exposed to these organic acids (acetic, succinic, citric, and oxalic acids) alone or in mixtures are provided in Table 1. The relative aggressiveness in terms of altered (layer depths) kinetics of the acid solutions is also given. The acids in question are commonly found in various organic leachates and effluents [3 – 7 ...
