SCMs in Concrete: Natural Pozzolans

Sep 22, 2017· These are sometimes referred to as true natural pozzolans In the plant As an SCM, natural pozzolans are typically used as a partial replacement for ordinary portland cement or as a substitution for fly ash The replacement or dosage rates vary depending on the pozzolan and the desired concrete characteristics and behavior...

pozzolan Topic

Jan 23, 2020· Pozzolan Definition: a siliceous or silico-aluminous material that will, in finely divided form and in the presence of moisture, chemically react with calcium hydroxide at ordinary temperatures to form compounds having cementitious properties (there are both natural and artificial pozzolans)- ACI Concrete Terminology...

Portland Pozzolana Cement (PPC)

The pozzolanic material is in finely divided form and the material mainly used for making portland pozzolana cement is fly ash and calcined clay The calcined clay has low carbon content and it can reduce carbon content to 30 percent when comparing to the production of ordinary Portland cement It can be used fro pozzolanic material for making PPC...

EP2536669A2

The supplementary material is incorporated into the pozzolan during its formation in the production plant and becomes an integral chemical constituent of the pozzolan By forming the pozzolan with the desired characteristics in the production plant, the pozzolan can have optimal performance when blended with Portland cement for use in concrete...

The use of pozzolans in concrete

Typically pozzolans are used as cement replacements rather than cement additions Adding pozzolans to an existing concrete mix without removing an equivalent amount of cement increases the paste content and decreases the water/cement ratio In other words, adding more pozzolans to a mix changes the mix proportions...

Portland cement

Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty groutIt was developed from other types of hydraulic lime in England in the late 19th century by Joseph Aspdin, and usually originates from limestoneIt is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker ....
