Greening of Mortars with Pozzolans

Journal of ASTM International, 2006
Abstract Growing interest in sustainable building has created a strong interest in fly ash and other coal combustion products (CCPs). Emergence of agencies like the U.S. Green Building Council (USGBC) and the Coal Combustion Products Partnership (C2P2) of the USEPA has accelerated this trend. Their primary goal is sustainable development,

The measurement of pozzolanic activity

Cement and Concrete Research, 1977
Abstract Some comments are made on the applicability of the hydrofluoric acid method for determining pozzolanic activity. It is pointed out that in addition to silica some other constituents of pozzolanic materials such as pfa are also soluble in HF and the conductance of the solution may, therefore, not be directly relatable to the active silica ...

Pozzolanas and Pozzolanic Materials

2019
Developments in concrete construction mean that there are now a broader range of cementitious materials, than have traditionally been available, providing options for engineers to meet specific technical requirements. Pozzolanas and pozzolanic materials from natural deposits or industrial processes represent a group within this category.

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 ...
