Estimation of pozzolana content in Portland pozzolana cement

Cement and Concrete Research, 1983
Abstract A simple and rapid method based on cold and dilute hydrochloric acid has been developed to determine pozzolana content in Portland pozzolana cements (PPC). The method is applicable to different types of pozzolana even in the absence of original samples of ingredients used in the production of PPC. A 5% (v/v) solution of HCl (sp. gr.

Pozzolana and Pozzolanic Cements—A Review Part I: Pozzolana

Transactions of the Indian Ceramic Society, 1981
In this review, different types of pozzolanas, their activity in relation to different factors, various methods for evaluation of their reactivity and their hydration etc have been discussed. Some of the important parameters by which the reactivity of a pozzolana is influenced have been stated to be microstructure, temperature of calcination and ...

Optimization of Conditions for the Determination of Pozzolana Content in Portland Pozzolana Cement and other Blended Cements

Transactions of the Indian Ceramic Society, 1989
Determination of pozzolana content in portland pozzolana cement (PPC) by the hydrochloric acid extraction technique has been already investigated. In the existing methods the varying degree of dissolution of pozzolana contents causes its over- or underestimation. This could be eliminated by using dilute hydrochloric acid (0.4 M) of known volume. In the
