Characterisation of Fly Ash and Relevance of Pozzolanic Reactivity
Advanced Materials Research, 2011ABSTRACT It is a very well known fact that the use of fly ash in masonry and concrete make the structures durable. Properties of Fly Ash depend upon coal source. For acceptability of fly ash in cement, mortar and concrete various specifications and standards are available.

Properties and pozzolanic reactivity of flash calcined dredging sediments
Applied Clay Science, 2016Abstract Dredging of ports, harbours and waterways generates vast amounts of sediments that find few applications and need to be disposed of. In the port of Antwerp, Belgium, each year 450,000 t (dry matter) of dredging sediments are mechanically dewatered and stockpiled. This paper investigates flash calcination of the clay-rich dredged sediments as

Mineralogical effect on the pozzolanic reactivity of a Mexican lacustrine soil
Construction and Building Materials, 2010Abstract Clay minerals have been used as natural pozzolans with the aim of reducing CO 2 emissions, and densifying the matrix with hydration products in pastes and mortars. This study assesses the pozzolanic reactivity of a natural lacustrine material in its natural and thermally-treated states.

The influence of particle size on the pozzolanic reactivity of quartz powder
Powder Technology, 1999Abstract Materials with cement-based matrices represent a class of materials notable for their wide and plentiful use. Up to the present, component reactivity was closely linked to the material's vitreous characteristics. The question we wanted to find an answer to was: is the pozzolanic reaction one which is specific to vitreous materials? To tackle

Effect of alkanolamines in kaolinitic calcined clays pozzolanic reactivity.
2023Five kaolinitic clays with different amounts of kaolinite, ranging between ~70 wt% and ~30 wt%, have been studied to unravel the possible activation effect of alkanolamines on the aluminate fraction of calcined clays. This is of interest for enhancing the reactivity of LC3 binders.

Alkali-Silica Reactivity of Mortars Containing Natural Pozzolan
2019Alkali-silica reactivity is one of the most recognized deleterious phenomena in Portland cement concrete resulting in cracks, spalling, and other deleterious mechanisms. The aim of this study was (i) to assess the extent of reactivity of the aggregates, quarried from seven different sources, suspected of being conducive to ASR, and (ii) to compare ...
