New method to assess the pozzolanic reactivity of mineral admixtures by means of pH and electrical conductivity measurements in lime:pozzolan suspensions
(Inst Ciencias Construccion Eduardo Torroja, 2014-01-01)
A very simple method based on electrical conductivity and pH measurements was proposed for assessing reactivity of pozzolans. Calcium hydroxide: pozzolan water suspensions were monitored by means of measurements of electrical ...
Indirect and direct Chapelle’s methods for the determination of lime consumption in pozzolanic materials
(IBRACONSão Paulo, 2015)
In this work, comments are made about indirect methods and direct Chapelle’s method applied to the determination of the reactivity of pozzolanic
materials. The Chapelle’s method is based on the lime-pozzolan reaction and ...
Pozzolanic behavior of bamboo leaf ash: Characterization and determination of the kinetic parameters
(ELSEVIER SCI LTD, 2011)
The paper presents a characterization and study of the pozzolanic behavior between calcium hydroxide (CH) and bamboo leaf ash (BLAsh), which was obtained by calcining bamboo leaves at 600 degrees C for 2 h in a laboratory ...

Assessment of pozzolanic/hydraulic reactivity of vitreous calcium aluminosilicate (VCAS)
(2016-04-15)
The aim of this paper is to assess the possibility of using vitreous calcium aluminosilicate (VCAS) as a supplementary cementitious material in the production of Portland cement mortars. The calcium hydroxide consumption ...
Influence of grinding on the pozzolanic activity of granite residue

Pozzolanic Reactivity Studies on a Biomass-Derived Waste from Sugar Cane Production: Sugar Cane Straw Ash (SCSA)
(2016-08-01)
Biomass has gained in importance as an energy source in recent years. One of the crops that presents interesting opportunities with regard to biomass is sugar cane. In Brazil, sugar cane production is increasing for alcohol ...
Thermal analysis to assess pozzolanic activity of calcined kaolinitic clays
(Springer, 2014-04)
The use of calcined clays as partial replacement of cement is encouraged since it promotes the reduction of the green-house gas emission and the energy requirement of cement-based material, maintaining or enhancing the ...
