Pozzolanic activity of palm bunch wastes
Materials and Structures, 1989The paper reports an investigation of the ash from the burnt stalks of oil palm bunches as a suspected agricultural waste with pozzolanic activity. Chemical analysis confirmed the presence of the major elements silica, alumina, potassium and a comparatively low content of calcium, all of which are necessary for pozzolanic activity.

An alternative thermal method for identification of pozzolanic activity in Ca(OH)2/pozzolan pastes
Journal of Thermal Analysis and Calorimetry, 2013Pozzolans play an important role in the industry of cement and concrete. They increase the mechanical strength of cement matrices and can be used to decrease the amount of cement in concrete mixtures, thus decreasing the final economic and environmental cost of production; also, as some of them are byproducts of industrial processes (such as silica ...

Pozzolanic behavior of thermally activated kaolin
"SP-132: Fly Ash, Silica Fume, Slag, and Natural Pozzolans and Natural Pozzolans in Concrete - Proceedings Fourth Interna", 1992In this study different clays were tested with various granular sizes and calcination parameters. The pozzolanic properties were investigated using metakaolin-lime mixtures by the evaluation of both the mechanical strength and combined lime. The mineralogical composition, particle size distribution and degree of amorphousness were the main factors ...

Summary of Methods for Determining Pozzolanic Activity
1950The testing of pozzolanic materials has been studied by investigators for over a hundred years. For the most part, strength values have been the basis used in comparing the results obtainable by quicker methods. However, inasmuch as some other quality may be more important than strength in specific applications of pozzolans, strength is not a universal
