Pozzolana and Pozzolanic Cements—A Review Part—II: Pozzolanic Cements

Transactions of the Indian Ceramic Society, 1983
In this review pozzolanic cements have been discussed. A certain amount of pozzolana can be mixed with Portland cement to yield pozzolanic cements and thus the mixture becomes economic as well as inter-reactive. The specific advantages are its better strength, improved workability, less heat of hydration, less shrinkage and greater resistance to ...

Pozzolans and the Pozzolanic Reaction

1990
The most often used mineral admixture in the modern concrete industry is the pozzolan. A pozzolan, and there are many of them, is defined as “siliceous or siliceous and aluminous materials which in themselves possess little or no cementitious value but will, in finely divided form and in the presence of moisture, chemically react with calcium hydroxide

Pozzolanic activity tests as a measure of pozzolans' performance. Part 1

Magazine of Concrete Research, 2007
The current methodologies used for the selection and classification of pozzolans present certain chemical and physical requirements that may restrict their use. A good example of this is the use of the pozzolanic activity index as the main parameter in the selection and classification of pozzolans. This is determined by several different methodologies
