Aνακύκλωση απορριμμάτων λατομείων και βιομηχανικών μονάδων στον τομέα των βιομηχανικών ορυκτών με σκοπό την παραγωγή νέων καινοτόμων υλικών
Translated title:
Recycling of mining and industrial waste in the field of industrial minerals for the production of new innovative materials
Summary:
Following current trends in green construction industry, mining and industrial
waste were evaluated and tested for the development of innovative products,
with lower energy footprint.
Neogene argillaceous sediments overlying lignite were used for the production
of lightweight ceramic bricks with improved thermal properties at lower
sintering temperatures. Byproduct from the enrichment process of
huntite-hydromagnesite was tested in white mortars of exterior wall layer,
aiming to an improved thermal behavior of building walls in fire events.
The methodology was developed based on the results of the characterization and
assessment of waste. Characteristic properties of final products were tested
and evaluated based on international standards, regulations and technical
instructions. Comparison with reference samples, commercial products and
quality specifications were performed.
At the outcome of the research it has been proposed the production of
lightweight ceramic bricks at lower firing temperatures by using waste
materials. Lightweight bricks present improved insulating properties, suitable
for low energy cost constructions.
Additionally, the huntite-hydromagnesite byproduct can substitute conventional
filler without changing the basic properties of mortar. At the same time, it
improves the behavior of the mortar, and generally of the masonry, in fire
events, by delaying heat flow and developing mechanical strength at high
temperatures.
