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 ...
Influence of calcination temperature on the morphology and magnetic properties of Ni-Zn ferrite applied as an electromagnetic energy absorber
(ELSEVIER SCIENCE SA, 2009)
An evaluation was made of the influence of calcination temperatures on the structure, morphology and eletromagnetic properties of Ni-Zn ferrite powders. To this end, Ni(0.5)Zn(0.5)Fe(2)O(4) ferrite powders were prepared ...
Rapid calcination of ferrite Ni0.75Zn0.25Fe2O4 by microwave energy
(Springer, 2014-10-01)
Ferrites Ni0.75Zn0.25Fe2O4 were obtained by polymeric precursor method and calcined in a short time with microwave energy to assess the morphological and microstructural characteristics. Samples were calcined at 500, 650, ...
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 ...
Volumetric deformations at early age on portland cement pastes with the addition of illitic calcined clay

Characterization and greenhouse evaluation of Brazilian calcined nonapatite phosphate rocks for rice
(AMER SOC AGRONOMY, 2008)
Little information is available on the agronomic effectiveness of calcined nonapatite phosphate rock (PR) sources containing crandallite minerals in the form of Ca-Fe-Al-P for flooded and upland rice (Oryza sativa L.). We ...
