pozzolanic

Manufacturing blended cement (also called pozzolanic cement) is one of the promising trends in the reduction of energy use in construction.

3. Innovative technologies related to the increased utilization of low-energy building materials 1995

· The reaction of cement and water (known as hydration) liberates calcium hydroxide (slaked lime) which reacts with the clay particles to form a kind of pozzolanic binder.

Chapter 4 1988

(d) use of low-energy additives or extenders, such as pozzolanic materials or blast-furnace slag, in cement production;

7. Strategies for optimizing use of energy in construction and in the production of building materials* 1995

This can prevent ion exchanges in clayey soils, without however, preventing the pozzolanic reaction.

Chapter 7 1998

This can prevent ion exchanges in clayey types of earth, without however, preventing the pozzolanic reaction.

Chapter 7 1998

The incineration of unretted pith produces an ash, which has pozzolanic characteristics, similar to those of rice husk ash, and can be used for making lime-pozzolana binders.

4. Innovative technologies related to recycling of materials 1995

The presence of iron oxides allows stabilization to occur efficiently with little cement, as a result of pozzolanic reactions or hardening effects.

Chapter 6 1995

This is a pozzolanic reaction, notably as obtained with lime.

Chapter 6 1995

This reaction uses up part of the lime otherwise available for pozzolanic reactions.

Chapter 7 1994

ORGANIC MATTER: These can block ionic exchange in clayey soils without, blocking the pozzolanic reaction.

Chapter 7 1994

For many years, researchers have assumed that the key to the ancient concrete’s durability was based on one ingredient: pozzolanic material such as volcanic ash from the area of Pozzuoli, on the Bay of Naples.
