Influence of the microsilica state on pozzolanic reaction rate

, 1999
[EN]Silica fume is generally supplied as an ultrafine powder in its original state, densified or in suspension. The difference in states should not influence the pozzolanic behaviour of this by-product in a cementitious matrix.

Thermal activation and pozzolanic reactivity assessments of Estonian clays for cementitious applications

This study evaluates the pozzolanic reactivity of locally sourced Estonian clays as supplementary cementitious material (SCM) alternatives. Two selected clays, Arumetsa (ARC) and Aseri (ASC), were calcined in a rotary tube furnace at three distinct ...

Role of Calcination Temperature in Governing Physicochemical Properties and High-Temperature Resistance of Lime–Calcined Clay Binders

Journal of Chemistry
The performance of lime–calcined clay binder systems is strongly influenced by calcination temperature, which governs their physicochemical properties, pozzolanic reactivity, and resistance to elevated temperatures.

Improving the pozzolanic reactivity of clay, marl and obsidian through mechanochemical or thermal activation

This research investigated the physicochemical properties and pozzolanic reactivity of mechanochemically and thermally treated clay, marl, and obsidian as supplementary cementitious materials (SCMs). The results suggest that the mechanochemical treatment

Investigation of a model system to characterize the pozzolanic reactivity of two low Ca fly ashes and a quartz powder

, 2011
Fly ash (FA) is increasingly used as clinker replacement in blended Portland cements in order to reduce the CO2 emissions /1/. The reactivity of the FA changes depending on its chemical and mineralogical composition and the pre-treatment, e. g.

Mechanical treatment for enhancing the pozzolanic reactivity of recycled powder from waste wind turbine blades

The pozzolanic reactivity of a recycled glass fibre reinforced polymer (GFRP)-derived supplementary cementitious material (SCM) was enhanced through mechanical treatment involving ball milling (120 rpm for 60–360 min).
