dc.description.abstract |
Alkali activated materials (geopolymers) are relatively new materials, thanks to their good
mechanical, physical, thermal properties and at the same time environmental friendliness,
they could be widely adopted in different fields. The experiments, described in this article,
are focused on the investigation of compressive strength of alkali activated materials based
on fly ash and red mud. For the following experiments were prepared five series of
samples with different ratio of red mud to fly ash. All the samples had the form of cubes
with dimensions 30mmx30mmx30mm. The tests on compressive strength were conducted
in 7, 28 and 56 days after final heat treatment. The test showed that the highest strength
had the samples with the smallest amount of red mud (5%). In 56 days it was 29 MPa.
Meanwhile the samples with the biggest amount of red mud (50%) were not even tested
because of samples cracking during heat treatment. |
