Pozzolanic activity of mechanochemically and thermally activated kaolins in cement
Cement and Concrete Research, 2015This paper reports on the mechanochemical activation by intensive grinding as an alternative way to produce pozzolanically reactive metakaolin. The physicochemical properties, pozzolanic reactivity and impact on cement hydration of mechanochemically and thermally activated kaolinitic clays were compared.

Alkali activated natural pozzolans for geopolymer cement
2021This thesis deals with the use of six natural pozzolans from Germany and Italy for geopolymer production. As the first part, a detailed study was conducted on the effect of silica modulus of sodium silicate solution and mineralogical composition of natural pozzolans on the extend of geopolymer reaction, reaction kinetics, mechanical properties, and ...

Durable "Green" Concrete from Activated Pozzolan Cement
Green Streets and Highways 2010, 2010Concrete is the most widely used man-made material, and the manufacture of portland cement - the active ingredient of concrete - accounts for 6 to 8 percent worldwide of all anthropogenic emissions of carbon dioxide, a leading greenhouse gas involved in global warming.

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

CHEMICAL METHODS FOR TESTING POZZOLANIC ACTIVITY
Various testing methods have been developed for determining the pozzolanic property and activity of a material. Some of these testing methods have been standardized while some are used as supporting methods. These are generally categorized as direct and indirect methods.KURUGÖL, Sedat, GÜLEÇ, Ahmet
