Abstract :In this study, the strength characteristics of the expanded perlite aggregate, waste marble dust and tragacanth added cement based composite material were investigated. A composite construction material was prepared using expanded perlite aggregate with a particle size of 0-2 mm and 2-4 mm  at the ratio of 10%, 30% and 50% by weight, waste marble powder produced by sieving through 0.25 mm sieve at the ratio of 10% and 20%, tragacanth at the ratio of 0%, 0.5% and %1 and CEMI 42.5 N type Portland cement. Density, compressive strength, abrasion loss, water absorption, compressive strength after elevated temperature and compressive strength after freezing-thawing tests were performed on these prepared composite samples. It was seen that compressive strength, compressive strength after elevated temperature, compressive strength after freezing-thawing and density values have decreased and abrasion loss and water absorption values have increased as expanded perlite particle size, expanded perlite ratio, tragacanth ratio have increased and waste marble powder ratio has decreased on the prepared samples .
