The concrete porosity can be reduced by controlling the water-cement ratio. However, reducing the water-cement ratio will eventually affect the workability of concrete . By adding the admixture in concrete, it reacts with the cement of fresh concrete ... osi monarch trainingIn general, the applications of stearic acid exploit its bifunctional character, with a polar head group that can be attached to metal cations and a nonpolar chain that confers solubility in organic solvents. The combination leads to uses as a surfactant and softening agent. Stearic acid undergoes the typical reactions of saturated carboxylic acids, a notable one being reduction to stearyl alcohol, and esterification with a range of alcohols. This is used in a large range of manuf… osimo news
