SYNOPSIS IN INTERLINGUA LE RELATION DEL INTENSITATE CALEFACTORI DE UN INVESTIMENTO DE GYPSO E LE FORMATION DE FIS-SUEAS.—Esseva investigate le relation inter le intensitate del calefaction de un modulo investimental de gypso e le formation de fissuras. Blocos cylindric de investimento revelava fissuras solmente quando lor calefaction esseva portate rapidemente (40 C per minuta) usque al temperatura de transformation de gypso. In anulos de modulage, fissuras esseva producite mesmo quando le calefaction rapide comenciava a levemente plus alte temperaturas atmospheric.
