The Possibilities of Using Tobacco Wastes in Producing Lightweight Concrete

This study was carried out to determine the possibilities of using tobacco wastes in lightweight concrete producing. The samples were produced with mixture combinations of materials such as tobacco waste, pumice, sand and cement. The results showed that produced material samples were in lightweight concrete class according to values of consistency, unit weight, porosity, compactness, compressive strength and thermal conductivity. It was determined that the unit weight of lightweight concrete material samples ranged between 0,50 – 0,56 kg dm-3,compressive strength values ranged between 0,20- 0,60 N mm-2 and thermal conductivity coefficients ranged between 0,194 – 0,210 W m-1 K-1. According to the observations, tests, experiments and evaluations on lightweight concrete material samples, it was concluded that the lightweight concrete with tobacco waste additives can be used as a coating and dividing material in constructions.
