Effects of calcining conditions on the microstructure of sugar cane waste ashes (SCWA): Influence in the pozzolanic activation
(ELSEVIER SCI LTD, 2009)
in this paper a study of calcining conditions on the microstructural features of sugar cane waste ash (SCWA) is carried out. For this purpose, some microparticles (< 90 mu m) of sugar cane straw ash and sugar cane bagasse ...
Effect of metakaolin pozzolanic activity in the early stages of cement type II paste and mortar hydration
(2008-04-01)
The cement industry is one which most emits polluting gases to the environment, due to the calcium carbonate calcination, as well as to the burning of fossil fuels during the manufacturing process. Metakaolin (MK), in ...
Calcined illite-chlorite shale as supplementary cementing material: Thermal treatment, grinding, color and pozzolanic activity
(Elsevier Science, 2019-10)
The thermal transformation (100–1100 °C) of two shales containing illite-chlorite (I/Ch), feldspars and quartz from La Cabañita quarry (Olavarria, Argentine) was studied by TG-DTA, XRD and FTIR. It included dehydration; ...
Characterization and properties of elephant grass ashes as supplementary cementing material in pozzolan/Ca(OH)(2) pastes
(Elsevier B.V., 2014-12-30)
This work presents the behavior of two elephant grass ashes, as pozzolans, elephant grass cameroon (EGC) and napier (EGN), calcined under controlled conditions (700 degrees C). The ashes were initially submitted to a ...
A study of the particle size effect on the pozzolanic activity of an equilibrium catalyst
(2011)
A study by thermogravimetry was done to evaluate the influence of the particle size on the pozzolanic activity of a residual equilibrium catalyst from a fluid catalytic cracking unit of a Brazilian refinery. For this ...
Thermal Treatment and Pozzolanic Activity of Calcined Clay and Shale
(American Concrete Institute, 2019-07)
Clayminerals are the most abundant raw materials for calcined pozzolans. Thermaltransformation includes dehydration, dehydroxylation, mineral collapse, andneo-formation. Depending on the type and amount of clay mineral, ...
Potential use of Argentine kaolinite clays as pozzolanic material
(Elsevier Science, 2014-11)
Different Argentine kaolinitic clays were selected to study their potential pozzolanic activity. The incidence of several factors such as the origin of deposits (primary or sedimentary clays), mineralogical composition, ...
Influence of grinding on the pozzolanic activity of granite residue
(Fundação Gorceix, 2020)
Evaluation of the Pozzolanic Activity of Uncontrolled-Combusted Sewage Sludge Ash
(2021-06-01)
Waste management is a crucial issue facing modern society. The generation of sewage sludge is increasing annually due to the urbanization and improvement of sanitation systems of cities. The construction sector has emerged ...
