Abstract
The paper presents the high-temperature evaluation of technical properties of geopolymer foamed slabs developed for the application as a thermal insulation. The thin geopolymer slabs were manufactured and tested in the experimental setup designed for the evaluation of slab-like elements under fire load. Two geopolymer mixes were used to compare their behaviour. The technology of mixing and preparation is described in the paper. The original experimental setup consists of the furnace that enables the heating of sample elements from one side with ISO-834-1 fire scenario by 140 kW gas burner [1]. The slab is placed horizontally on the top of the furnace and heated from the bottom in a window 600 x 600 mm. During the test, the temperature gradient between the heated and unheated surface is monitored. Additionally, the propagation of cracks is analyzed during the fire test. After the test, the integrity of elements is evaluated. The analysis of thermal gradient and its changes during the test let us conclude on fire resistance of tested element as well as the degree of thermal damage of the material. According to the tests under high-temperature conditions that have been carried out at out laboratory recently [2], the possible sintering and droplets are additionally monitored during the tests.
