Se presenta una técnica de ensayo que permite obtener resultados reales de deformación bajo carga a elevadas temperaturas .
Se ensayaron siete arcillas refractarias argentinas, en estado natural y previamente calcinadas a 1 450°c. Se presentan las curvas de aplastamiento obtenidas y las características físico-químicas de los materiales ensayados.
Se exponen conclusiones referentes al método de ensayo y al comportamiento de las arcillas estudiadas.
Como complemento se dan a conocer los resultados obtenidos en ensayos realizados sobre ladrillos refractarios sílico- aluminosos de fabricación nacional.
A testing technique is presented which allows to obtain more accurate results of deformation under load at high temperatures .
Seven refractory clays were tested, in his natural state and heated at 145°C. Curves of deformation under load obtained and physico-chemical chracteristics of tested materials are given.
Conclusions are drawn with reference to the testing method and the behaviour of studied clays.
As a complement, results obtained when testing a series , of silico-aluminous refractory bricks, are included.
