Özet
Engineers have to know mechanical characteristics of lightweight concretes which are better than
normal concretes. In this study, experimental investigations are performed for obtaining new concrete
types to investigate the effect of lightweight aggregates on mechanical properties and to evaluate the
relationships between the measured values of these properties. For this purpose, different types of
concrete samples were prepared with a constant w/c, and normal aggregates replaced by lightweight
aggregates such as pumice, expanded perlite and rubber aggregates at different volume fractions such
as 10 %, 20 %, 30 %, 40 % and 50 % of the total aggregate volume. 102 samples were produced, and
their mechanical characteristics were tested in accordance with ASTM and EN standards. Moreover,
in order to evaluate possible correlations among the tested properties, a multivariate regression
analysis was performed. Based on the experimental results, the expressions are presented to determine
the relation between the mechanical properties of concrete samples. The results showed that both the
compressive strengths and bulk densities of lightweight concrete samples decreased with increasing
the (%) percentage of lightweight aggregate content. In addition, the regression analysis results show
that if one of the mechanical properties of a structure is known, the other important properties can be
calculated easily utilizing those expressions.
