Kaolinitic calcined clays - Portland cement system: Hydration and properties
This paper examines the influence of type of kaolinite in the raw clay on the performance of calcined clays as supplementary cementing materials. Two kaolinitic clays were characterized, calcined then ground and used as ...
Pozzolanic activity of calcined halloysite-rich kaolinitic clays
(Elsevier Science, 2017-10)
The aim of this study is to determine the pozzolanic activity of clays with high content of halloysite/kaolinite, and to evaluate the influence of halloysite/kaolinite ratio and halloysite morphology in the development of ...
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 ...
Thermal analysis to assess pozzolanic activity of calcined kaolinitic clays
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 ...
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, ...
High Purity Mullite by Slip Casting Method from Calcined Alumina and Kaolinitic Clay
The mullite – 3Al2O3.2SiO2-, has different applications, specially in refractory materials, as it is the silicoaluminous refractory material for excellence. The most frequent methods used to prepare mullite are based on ...
Preparation and characterization of a Brazilian bentonite clay for removal of copper in porous beds

Estudo térmico e adsortivo de argisolo caulinítico da região amazônica
(Universidade Estadual Paulista (UNESP), 2016)
Production and quantification of high-purity mullite at 1600°C from kaolinitic clay and calcined alumina
A study is performed to determine the reaction time which is required at 1600°C to obtain mullite from clay with a high content of kaolinite (clay from the La Rioja Province of Argentina) and from a stoichiometric mixture ...
