pozzolanic

The main field of application is as pozzolanic material for high performance concrete.

This results in a higher surface to volume ratio and a much faster pozzolanic reaction.

Pozzolanic materials are occasionally added to give a much harder wearing paint finish.

A quantification of this capability is comprised in the term pozzolanic activity.

Plasticizers are also often used when pozzolanic ash is added to concrete to improve strength.

The pozzolanic mortar used had a high content of alumina and silica.

The fly ash is pozzolanic, so that ultimate strength is maintained.

However, the supply of high-quality pozzolanic by-products is limited and many local sources are already fully exploited.

There are inorganic materials that also have pozzolanic or latent hydraulic properties.

Prolongued grinding results in an increased pozzolanic activity by creating a larger specific surface area available for reaction.

The filler effect is immediate, while the effect of pozzolanic reaction occurs between 3 to 14 days.

PFA can undergo a pozzolanic reaction and become brittle over time.

These were used by pozzolanic reaction.

The Romans later improved the use and methods of making what became known as pozzolanic mortar and cement.

When added to lime mortar, synthetic zeolites can act simultaneously as pozzolanic material and water reservoir.

Physical surface adsorption is not considered as being part of the pozzolanic activity, because no irreversible molecular bonds are formed in the process.

Alternatively, a pozzolanic material such as calcined clay or brick dust may be added to the mortar mix.

Similarly, materials showing structural disorder such as glasses show higher pozzolanic activities than crystalline ordered compounds.

A pozzolanic material is by definition capable of binding calcium hydroxide in the presence of water.

Or Pozzolanic reaction is also faster set chemical reation of calcium silicate hydrate.

It is known as a "pozzolanic" material, one that resembles the volcanic ash from Mount Vesuvius.

But pozzolanic reacted cement has lower compressive strength at 15 MPa maximum.

Other methods indirectly determine the extent of the pozzolanic activity by measuring an indicative physical property of the reacting system.

The pozzolanic reaction is the chemical reaction that occurs in portland cement containing pozzolans.

Because of its spherical shape and pozzolanic properties, fly ash is useful in cement and concrete applications.
