Opis:
Wherever industrial development exists, environmental pollution increases day by day. The heavy metals play an important role in soil and environmental pollutions and directly affect the human being lives. In this study, we determine pollutions resulting from heavy metal particles emanating from the brake discs pads of the vehicles on high ways and nearby factories. The field work was carried out in İzmir-Aliağa industrial area. Magnetic susceptibility measurements were done at a long profile crossing the İzmir-Çanakkale highway that goes through the study area. Here, we have determined the effect of heavy metals causing pollution in the surroundings. The studies indicate that the average acceptable values of magnetic susceptibility in such areas is about 0-50×10¯⁵ SI. Here we show that the magnetic susceptibility measurement values obtained along our study profile are about 18 times the acceptable ranges.

Opis:
Lightweight aggregates, used to produce cavity blocks in the construction sector, vary according to their technical properties and thus, technical analyses should be performed on lightweight aggregate specimens. Lightweight aggregates, like pumice, are widely employed for the production of construction elements, used as light masonry units. In literature there are studies related to applications of various lightweight aggregates, such as volcanic slag, ignimbrite and expanded clay, in addition to pumice, to produce porous cavity blocks. This study investigates the usability of perlitic pumice formations, present around Menderes, İzmir (Turkey), as lightweight aggregate. Many experiments were conducted to investigate this possibility and to determine the optimum mixing ratios of aggregate. Based on the results, for 10% of cement by volume, the optimum aggregate mixing ratio was 40% 0-4 mm and 60% 4-8 mm.
