Limestone-filled pozzolanic cement

Cement and Concrete Research, 2000
Fillers are specially selected, natural or artificial inorganic materials, which improve the physico-chemical and mechanical properties of the cement such as workability or water retention. They can be inert or have slightly hydraulic, latent hydraulic or pozzolanic properties.

Evaluation of pozzolanic activity of natural and artificial pozzolans by thermal analysis

Thermochimica Acta, 2004
Abstract In this research, the pozzolanic activity of natural and artificial pozzolan used for preparation of restoration mortars was evaluated. For this purpose, several pastes were prepared, by mixing two artificial pozzolans and a natural one with commercial hydrated lime, in different ratios. The pastes were cured in standard conditions (RH = 98%,

Pozzolanic Activity of Diatomaceous Earth

Journal of the American Ceramic Society, 2010
Lime–diatomaceous earth cement pastes were fabricated at room temperature starting with a mixture of diatomaceous earth (DE), lime, and water. The cementing phase, associated with the pozzolanic reaction of the diatom skeletons with lime, was identified as calcium silicate hydrate (C–S–H) gel using X‐ray diffraction, scanning ...

Natural pozzolans for concrete

Economic Geology, 1951
Many geologic formations in the United States yield pozzolans or materials which can be converted into pozzolans by grinding and calcination. When properly selected, processed, and used, pozzolans will reduce costs, improve quality of concrete, protect concrete against effects of reaction between aggregate and cement alkalies, and inhibit attack by ...

The Omani Artificial Pozzolans (Sarooj)

Cement, Concrete, and Aggregates, 2001
Abstract Sarooj is a local Omani term for artificial pozzolana produced by calcining clays. Calcined clay mixed with lime and water has been used as a cementing material for a long time. It has been used widely in hydraulic structures due to its good hydraulic properties and in military defensive installations due to its durability. This

Pozzolanicity of Calcined Clay

2015
Out of the three major clay mineral groups, viz, kaolin, smectite and palygorskite – attapulgite, the cement science primarily focuses on the first group to be used on calcination as a pozzolanic admixture. The general understanding is that the dehydroxylation of dehydrated kaolinite in the temperature range of 550 – 650 °C apparently yields an x-ray ...
