Modification of the lightweight aggregate with the use of spent zeolite sorbents after the sorption of diesel fuel

Franus M., Bandura L., Franus W.

The paper presents the investigation of lightweight aggregate that can be obtained from the mass of raw material modified by clay minerals, zeolites and waste. In this experiment it was modified by zeolites – clinoptilolite and Na-P1, which were used for the removal of diesel fuel. That kind of substances can get into the environment in an uncontrolled way causing the ecological risk. The spent sorbent containing fuel constitutes waste, which should be utilized. This process prevents petroleum substances from reentering to the environment.The spent zeolite (10%) was added to the clay (90%) originated from “Budy Mszczonowskie” bed. Homogenization process consisted in mixing the ingredients with water until a plastic consistency was formed. The formed beads of coarse fraction of 8-16 mm were dried for 2h in a laboratory oven at 110 °C and then fired at 1170 °C. The obtained aggregates were tested on the basis of appropriate standards in order to determine their physical and mechanical properties.The research indicates that the lightweight aggregate obtained from clay and zeolites used for the removal of petroleum compounds is a valuable building material. The porous structure of each bead, closed with durable ceramic coating, provides the aggregate with a lot of functional properties.
