Sulfate performance of calcined illitic shales
(Elsevier, 2021-07)
In the past, calcined pozzolans were largely used in massive concrete, and nowadays, they appear as an excellent alternative to reduce the clinker factor in general use cement. The pozzolanic activity of two calcined illitic ...
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 ...
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, ...
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; ...

(Universidad Nacional de Misiones. Facultad de Ciencias Exactas, Químicas y Naturales. Secretaria de Investigación y Posgrado, 2021-03-23)
Ciertos países actualmente cuentan con sistemas que emplean la energía solar en diversos procesos industriales. Estos sistemas tienen la ventaja de disminuir el empleo de combustibles fósiles y con ello la generación de ...
Thermal requirements to obtain calcined and frits of ulexite
(Elsevier Science, 2007-01)
Ulexite has a substantial amount of hydration water, which allows using calcination methods to increase the B2O3 content from 42.97 to 66.69%, due to the loss of 35.54% of its weight, corresponding to its hydration water. ...
