MECHANICAL PROPERTIES OF THE COMPOSITE MATERIAL PRODUCED BY THE MIXTURE OF EXPANDED PERLITE, WASTE MARBLE DUST AND TRAGACANTH

In this study, the strength characteristics of the expanded perlite aggregate,waste marble dust and tragacanth added cement based composite materialwere investigated. A composite construction material was prepared usingexpanded perlite aggregate with a particle size of 0-2 mm and 2-4 mm at theratio of 10%, 30% and 50% by weight, waste marble powder produced bysieving through 0.25 mm sieve at the ratio of 10% and 20%, tragacanth at theratio of 0%, 0.5% and %1 and CEMI 42.5 N type Portland cement. Density,compressive strength, abrasion loss, water absorption tests were performedon these prepared composite samples. It was seen that compressive strengthand density values have decreased and abrasion loss and water absorptionvalues have increased as expanded perlite particle size, expanded perliteratio, tragacanth ratio have increased and waste marble powder ratio hasdecreased on the prepared samples.
