Özet
Due to the rapid depletion of available sites, the disposal of waste tires is becoming a serious
environmental problem day by day. Assessment of waste rubbers in concrete is an innovative solution
that meets both the challenge of the tire disposal problem and a demand for improved thermal
performances of structural materials for energy efficient buildings. Therefore, in this study, an
investigation is performed both to obtain new concrete types by using waste rubbers with high thermal
insulating characteristics and to compare the thermal performance of those concretes with
conventional ones. For this purpose, different types of concrete samples were prepared with a constant
water-cement ratio, and normal aggregates replaced by rubber aggregates at different volume
fractions between 0% and 60% of the total aggregate volume. In the experiments, all mechanical tests
were conducted and the hot disk method was used to establish thermal property values of concrete
samples. In order to determine the most suitable concrete samples, heat flows through the produced
samples are calculated using a program developed in MATLAB. Calculation method for the heat flow
is based on solution of transient heat transfer problem for the multilayer structures. The program is
executed to calculate hourly heat gain values for these samples over a period of 24 h during design
day for Batman, Turkey. The results indicated that the maximum reduction in heat gain value was
obtained as 50.6 % for RC60 wall with commonly used thickness of 20 cm corresponding to
conventional concrete.
