(Instituto Geológico, Secretaria do Meio Ambiente, São Paulo, 2003)
Influence of grinding on the pozzolanic activity of granite residue
(Fundação Gorceix, 2020)
Blended cements with limestone filler and kaolinitic calcined clay: Filler and pozzolanic effects
(American Society of Civil Engineers, 2017-09)
In this paper, binary and ternary blended cements (BC) based on calcined clay (CC, 0-30%) obtained from low-grade kaolinitic clay and limestone filler (LF, 0-10%) were developed and the interaction between the filler effect ...
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 ...
Thermogravimetry on calcined mass basis - hydrated cement phases and pozzolanic activity quantitative analysis
(Springer, 2009-07-01)
When cement hydrated compositions are analyzed by usual initial mass basis TG curves to calculate mass losses, the higher is the amount of additive added or is the combined water content, the higher is the cement 'dilution' ...

Investigating the possible usage of elephant grass ash to manufacture the eco-friendly binary cements
(Elsevier B.V., 2016-03-10)
In recent years, agro-industrial residues are focusing attention worldwide as a new source of pozzolans; in Brazil one of the wastes generated from agro-industrial activities comes from elephant grass that is cultivated ...
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 ...
Effect of thermal treatment on pozzolanic activity of excavated waste clays
(Elsevier, 2019-06-30)
Samples of excavated waste clays were characterized by X-ray fluorescence, laser granulometry, specific surface area, X-ray diffraction, and thermo-gravimetric analysis. Excavated clays were calcined at 550 ºC and 650 ºC ...
