carbonatation

There are several systems of carbonatation, named from the companies that first developed them.

The whole process takes place in "carbonatation tanks" and processing time varies from 20 minutes to an hour.

The clear juice from carbonatation is generally known as "thin juice".

The resulting syrup is either treated by a carbonatation or a phosphatation process.

These resources will rapidly degrade due to chloride attack and carbonatation.

The carbonatation process is used in the production of sugar from sugar beets.

Up to about 500 C, the major structural changes are carbonatation and coarsening of pores.

This carbonatation process will start at the surface, then slowly move deeper and deeper into the concrete.

The clear juice is then gassed further in another tank ("2nd carbonatation") and filtered.

It is installed after carbonatation and filtration and before evaporation.

Structural tests in the 1980s revealed significant deterioration in the concrete as a result of carbonatation.

A sufficient thickness of concrete cover is thus required in order to slow down the carbonatation process towards the rebar.

Non-hydraulic lime can only set through carbonatation (re-absorption of CO).

The carbonatation reaction takes place during lime softening (Clark's process) in water softening.

Concrete in buildings that experienced a fire and were left standing for several years shows extensive degree of carbonatation from carbon dioxide which is reabsorbed.

They are alkaline and therefore inhibit microbial growth, and reduce carbonatation of cementitious materials.

Carbonatation involves the following effects:

Non-hydraulic lime mortar sets/hardens by reaction with atmospheric carbon dioxide (called 'carbonatation').

In civil engineering, to determine the carbonatation spread in concrete structures and therefore assess the state of the rebar's passivation film.

This is a problem because the first line of defence of all structural elements against carbonatation, chlorides, frost and abrasion, is the cover zone.

The rate of carbonatation is dependent on the relative humidity of the concrete - a 50% relative humidity being optimal.

Dorr (also Dorr-Oliver) - a continuous process using two tanks with recycling ("1st carbonatation") to build up particle size for natural flocculation.

Limewater turns milky in the presence of carbon dioxide due to formation of calcium carbonate, a process called carbonatation:

Carbonatation of concrete along with chloride ingress are amongst the chief reasons for the failure of reinforcement bars in concrete.

During this period most of the excess calcium hydroxide reacts with the carbon dioxide in the air to form less caustic calcium carbonate (carbonatation).
