pozzolana, also spelled pozzuolana, hydraulic cement perfected by the Romans and still used in some countries, traditionally made by grinding a material of volcanic origin (the pozzolan) with powdered hydrated lime. Roman engineers used two parts by weight of pozzolan mixed with one part of lime to give strength to mortar and concrete in bridges and other masonry and brickwork.

In cement, lime and pozzolan industry, the production limiting factor is usually related to the operation of exhaust fan. An example is false air inlet into the kiln or combustion chamber. The unwanted excess of air increases the air flow moved by the exhaust fan, but does not result in an increase in clinker production.

Aug 19, 2014 Lime pozzolan concrete aims to be a more sustainable, low-carbon alternative to Portland cement and similar conventional examples of reinforced concrete. It is based on an ancient cement binding technology that combines naturally occurring pozzolanic materials - such as volcanic ash - with slaked lime to produce concrete that can be ...

Portland Pozzolana cement is integrated cement which is formed by synthesising OPC cement with pozzolanic materials in a certain proportion. It is commonly known as PPC cement. In this article we discuss about the properties, manufacture, characteristics, advantages and disadvantages of Portland Pozzolana cement.

Jan 10, 2017 The secret of Roman Cement was the mixing of lime with pozzolana, called harena fossicia or “pit sand” by Vitruvius. Pozzolana was distinguished from river and sea sands (the common harena) and receives this contemporary name from the town of Pozzuoli (Roman Puteoli, neighboring Baiae) in the Bay of Naples just 25 miles east of Mount Vesuvius.

Oct 06, 2017 A cement sand mortar of 1:6 mix can be better replaced by a mortar made by mixing one part of hydrated lime, two parts of clay pozzolana and eight parts of sand. In conjunction with the standard quality dry hydrated lime, these can be used for preparation of mortar and plasters having the same strength as that of cement sand mortars.

These pozzolanic reaction products fill in pores and result in a refining of the pore size distribution or pore structure. This results in a lowered permeability of the binder. The contribution of the pozzolanic reaction to cement strength is usually developed at later curing stages, depending on the pozzolanic activity.

Portland-pozzolana cement is produced by grinding together Portland cement clinker and artificial pozzolana (Fly ash) with addition of gypsum or calcium sulphate. Fly ash is a very fine material produced as a residue precipitated electro-statically or mechanically from the exhaust gases of coal-fired thermal power station.
