In some cases, they catalyze the C3S hydration reaction to produce earlier initial set and strength. Cement additives with retarding properties improve the flow and set properties of cement. Na/Ca chlorides and Na acetate/formate are helpful for increasing early strength of cement. Polymer-based additives can contribute to the fluidity of the mix.


Sodium Acetate Anhydrous is the anhydrous, sodium salt form of acetic acid.Sodium acetate anhydrous disassociates in water to form sodium ions (Na+) and acetate ions. Sodium is the principal cation of the extracellular fluid and plays a large part in fluid and electrolyte replacement therapies. Sodium acetate anhydrous is used as an electrolyte replenisher in isosmotic solution for parenteral ...

"Sodium acetate, on the other hand, has proven its ability to preserve and even increase the compressive strength of concrete under harsh weather conditions." To test their ideas, the researchers produced 72 concrete cubes with varying mixes of sodium acetate, which were then cured at either -25°c or +60°c for seven or 28 days.


For cement grinding, the present inventors discovered that triisobutylphosphate may be advantageously used at a dosage of 1-5% by weight based on non-volatile component of KAOW material. Exemplary KAOW-containing cement grinding additive composition of the present invention comprise KAOW, diethyleneglycol, glycerin, and triisobutylphosphate.


Triethanolamine is used as organic additive (0.1 wt%) in the grinding of cement clinker. It facilitates the grinding process by preventing agglomeration and coating of the powder at the surface of balls and mill wall. Triethanolamine is also used primarily as an emulsifier and surfactant. It is a common ingredient in formulations used for both ...


Grinding aids have been researched and used for decades to reduce energy consumption in the process of cement production. In this work, the effects of new alkanolamines, such as N,N-bis(2-hydroxyethyl)isopropanolamine (DEIPA), N,N-bis(2-hydroxypropyl)-2-aminoethanol (EDIPA) and N,N,N′,N′-tetrakis(2-hydroxyethyl)ethylenediamine (THEED), on the grinding, flowability and …

The solution was titrated with a sodium hydroxide solution with a concentration of 0.3226 g L −1 to a reddish color, and the volume of the sodium hydroxide solution used was recorded. Then, 20 mL of sodium acetate-acetic acid buffer solution was immediately added, and 4 to 5 drops of xylenol orange indicator were added.


In all phases, the samples were immersed in solutions of potassium acetate, sodium acetate, sodium formate, and urea in addition to control samples immersed in distilled water. Test results showed that asphalt cores exposed to large number of freeze-thaw cycles while immersed in a deicing solution would suffer a loss of strength and elasticity.

concentrations, sodium chloride and calcium chloride have a relatively small negative impact on the properties of concrete. At high concentrations, sodium chloride has a greater but still relatively small negative effect. At low concentrations, magnesium chloride and calcium magnesium acetate can cause measurable damage to concrete.
