Sep 22, 2017· The high material fineness along with the different calcination process results in metakaolin exhibiting behaviors different from ordinary calcined clays. Some materials, like volcanic ash, can exhibit pozzolanic behavior in their raw form without calcination or extensive processing. These are sometimes referred to as true natural pozzolans.
A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces is the most widely used material in existence and is only .

Franco Massazza, in Lea''s Chemistry of Cement and Concrete (Fourth Edition), 1998. CONCLUDING REMARKS. Pozzolana cannot remove all durability problems, but it can contribute to solving most of them provided that it is appropriately used. The main conclusion of the effect of pozzolanic materials on the durability of concrete can be summarised as follows.
Pozzolana is constituted of magma and volcanic ash, which are known as the best additives for cement conversion. Naturally available pozzolana is the only raw material which can be used along with lime to form hardened cement. Features: Easy to install. Low operational costs. Low maintenance needs.
Portland Pozzolana Cement manufactured by combining Pozzolanic materials. Pozzolana is a natural or artificial material which contains silica in the reactive form. This cement comprises of OPC clinker, gypsum and pozzolanic materials in certain proportions.
PPC is a variation of OPC which includes a mixture of pozzolanic material which is known to increase the strength of concrete. The raw materials used for manufacturing of PPC is OPC, gypsum, pozzolanic material such as fly ash, rice husk ash, volcanic tuffs and pumicites, clay and shale etc. Best choice for mass concreting, plastering and masonry.

Franco Massazza, in Lea''s Chemistry of Cement and Concrete (Fourth Edition), 1998. Workability. The use of a pozzolanic material whose fineness is similar to that of the Portland cement does not change the workability of mortars very much. Generally, natural pozzolanas slightly decrease the workability of mortar whereas lowcarbon fly ashes improve it. 323 High .
