HQ-Pozzolan increases service life and reduces the net greenhouse gas emissions (GHG) and energy consumption for a cubic yard of concrete. For every ton of cement replaced by HQ-Pozzolan, there is a net reduction of 0.86 tons of CO2 emissions. This means that every 21 ton truckload used is equivalent to taking three automobiles off the road. In addition, the heat saved is 4.29 million BTU's ...

The approach to the iconic UN Plaza was completely resurfaced with high performance permeable pavers made with Pozzotive pozzolan by Unilock, North America's premier manufacturer of concrete interlocking pavers. Illustrating an optimal circular economy, the pavers were made from the 60 tons of window glass that were harvested by Skanska Construction from the UN General Assembly Building.

L. Black, in Sustainability of Construction Materials (Second Edition), 2016 17.2.3 Effect of pozzolana on concrete performance. Blending pozzolana with cement can affect the early and late-age properties of concrete. The precise effects are very dependent upon the nature of the pozzolan. Pozzolana generally improve paste cohesiveness, thus reducing segregation.

A pozzolan is an important component of high-performance concrete because of the unique chemical reaction that takes place in the concrete mix. When cement is hydrated in a concrete mix, the resulting chemical reaction produces a number of compounds, the most important of which is the cement paste that binds the aggregates into a hard matrix. Cement paste is referred to as calcium silicate ...

Pozzolan is a finely powdered material which can be added to lime mortar to increase durability and, in the case of lime putty mixes, to provide a positive set. The addition of pozzolan to any lime mortar (hydraulic or non-hydraulic) will modify its characteristics. Pozzolanic materials can combine with uncarbonated lime (calcium hydroxide) to form stable compounds, thus reducing the risk of ...

What They Do. As silicate-based materials, pozzolans will react with the calcium hydroxide generated by hydrating cement to form additional cementitious materials. Calcium hydroxide (lime) accounts for up to 25% of the hydrated Portland cement but it does not contribute to the concrete's strength or durability. Pozzolans combine with the lime ...

Although pioneered by the ancient Greeks, it was the Romans that eventually fully developed the potential of lime-pozzolan pastes as binder phase in Roman concrete (lime, sand, crashed clay brick or ceramics /cocciopesto/, volcanic ash /pozzolana/) which was used for buildings and underwater construction.

Pozzolan refers to any of several silicate materials that produce cement-like materials when they react with calcium hydroxide. Pozzolans are typically used as a substitute for cement to produce concrete because they reduce the likelihood of corrosion due to sulfate attacks. Advertisement.
