Kaolinitic calcined clays - Portland cement system: Hydration and properties
(Elsevier, 2014-08)
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 ...
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 ...
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 ...
Concretes with Calcined Clay and Calcined Shale: Workability, Mechanical, and Transport Properties
(American Society of Civil Engineers, 2020-05-30)
This paper analyzed the eco-efficiency of concretes (water/cement ratio = 0.50; cement content=350 kg/m3, and slump = 7 cm) with blended cement containing 25% by weight calcined pozzolan obtained from a low-grade kaolin ...
Volumetric deformations at early age on portland cement pastes with the addition of illitic calcined clay
