Water Absorption Capacity of Irind Mine Pumice
Keywords:absorbent, pumice, water absorption, particle sizes, porosity
Water absorption capacity of Irind mine pumice depending on the particle size and absorption time is presented in the paper. Irind pumice is an aluminosilicate rock, with well-developed porosity, mechanical strength, high buoyancy, chemically inert, eco-friendly and exhibits sufficient water absorption capacities. The examination of the pumice by X-ray diffractometry has shown that it is a volcanic rock and is composed of cristobalite and coesite. The following particle sizes were selected for the study: 1.5… 2.0 mm, 2.5 ... 5.0 mm. Water absorption capacity of pumice was determined depending on the absorption period. The maximum water absorption was observed for particle sizes ranging from 2.5 to 5.0 mm.
