hydration reaction

This causes the heat given off by the hydration reaction to develop at a slower rate.

In the next few days the mixture would undergo a chemical hydration reaction similar to the setting of cement.

The reverse of a dehydration reaction is a hydration reaction.

This compound is primarily produced by combining water and propene in a hydration reaction.

The hydration reactions of calcium aluminate cements are very complex.

Hydration reactions are all reversed by heating to drive off the water of hydration.

One of the more complex hydration reactions utilises sulfuric acid as a catalyst.

Norbornene undergoes an acid-catalyzed hydration reaction with water to form norborneol.

This starts hydration reactions, which result in long, interlocking crystals forming around the aggregates.

The acceleration of the Portland cement hydration reactions can also partially accommodate the loss of early strength.

This hydration reaction involves considerable increase in volume with concurrent deformation of the original textures.

For instance the hydration reaction of an alkene and the dehydration of an alcohol are addition-elimination pairs.

The term hydraulicity or hydraulic activity is indicative of the chemical affinity of the hydration reaction.

While hardened concrete appears solid, it is porous, having small capillaries resulting from the evaporation of water beyond that required for the hydration reaction.

A hydraulic binder is a material that can set and harden submerged in water by forming insoluble products in a hydration reaction.

It is caused partly by chemical volume changes, but mainly by self- desiccation due to loss of water consumed by the hydration reaction.

The hydrate can be reconverted to quicklime by removing the water by heating it to redness to reverse the hydration reaction.

"Using incongruent, equilibrium hydration reactions to model latter-stage crystallization in plutons: examples from the Bell Island tonalite, Alaska".

It undergoes a hydration reaction, catalyzed by gold(III) or mercury(II), to give acetophenone.

Alkenes engage in an acid catalysed hydration reaction using concentrated sulfuric acid as a catalyst that gives usually secondary or tertiary alcohols.

From the above equations for the solubility product, the hydration reaction and the two acid reactions, the following expression for the maximum [Ca] can be easily deduced:

Also, water that is not consumed by the hydration reaction may leave the concrete as it hardens, resulting in microscopic pores(bleeding) that will reduce the final strength of the concrete.

Because the hydration reaction of sulfuric acid is highly exothermic, dilution should always be performed by adding the acid to the water rather than the water to the acid.

Dephosphorylation involves removal of the phosphate group through a hydration reaction by addition of a molecule of water and release of the original phosphate group, regenerating the hydroxyl.

The technique, known as in-situ chemical fixation, involves boring overlapping holes so that all the contaminated soil is treated and then left bound up in what engineers call a cement-soil hydration reaction structure.
