Özet
Perlite is a siliceous volcanic glass that provides heat and sound insulation,
whose volume can expand substantially under the effect of heat. Perlite ore
is one of the most important mineral resources for Turkey where holds a
large portion reserves in the world. Evaluation of perlite in building
industry, which has advantages in terms of heat and sound insulation, will
make an important contribution to the national economy. In this context,
experimental investigations are performed for obtaining new concrete types
with relatively high strength, low density and good thermal and acoustic
properties for energy efficient buildings. For this purpose, 6 sets and
different types of concrete samples were prepared with a constant watercement ratio, and normal aggregates replaced by expanded perlite
aggregates at different volume fractions such as 10%, 20%, 30%, 40%, 50%
and 60% of the total aggregate volume. Mechanical and thermal tests were
all conducted and the hot disk method was used to establish thermal
property values of concrete samples. The results of the experimental studies
show that the compressive strength and density decreases, while highly
increases the heat and sound insulation features with increasing in perlite
content. As a result, it was found out that the reductions in thermal
conductivity [Wm–1K–1] and ultrasonic pulse velocity [km/s] of the
produced samples reached to 75% and 35%, respectively.
