Abstract

Today,
fossil fuels are used primarily in energy production throughout the world.
However, the ever-diminishing energy production and developing technology has
encouraged energy recovery, saving or different topics. Grafen is one of the
most remarkable studies in the field of nanotechnology in recent years. This
nanotechnological product, considered as one of the mainstream products of
future technology, has superior properties in some physical and chemical issues
compared to many materials. Because of its high conductivity and durability, it
continues to attract attention in energy and materials science. In this paper,
the concrete samples obtained by mixing the graphene at certain ratios were
compared with pure concrete (graphene free concrete) and the thermal
conductivity of the grafen added concrete
was determined. Finally, the thermal conductivity of the pure concrete (thermal
conductivity of 1.3096 W/mK) added with 1 gr, 2 gr, 3 gr, 4 gr and 5 gr
graphene were calculated as 1.6516, 1.6668, 1.6773, 1.8080 and 1.8486 (W/mK), respectively.
