Description: In this study, the characteristics of the natural light aggregate located in a large area near the Erzurum Bridge District and the light concrete produced with this light aggregate are identified and the possibilities of use in the local agricultural structures are studied. For this, the characteristics are determined with the agrega of 75 kg/m3, 100 kg/m3, 125 kg/m3, 150 kg/m3, 175 kg/m3, 200 kg/m3, 225 kg/m3, 250 kg/m3, 275 kg/m3 and 300 kg/m3 cement content of 10 classes of light concrete is produced taking into account the relevant Turkish Standards. The characteristics of the produced light concrete are identified, such as unit weight, water absorption, pressure resistance, drawing resistance. According to the achieved values, with the use of the natural light aggregate here in light concrete manufacturing, the local heat insulation is good, so resistant to earthquakes and therefore better quality agricultural structures than the material such as stone and curtain can be economically constructed.   A RESEARCH ON USAGE POSSIBILITIES OF NATURAL LIGHTWEIGHT AGGREGATE PROCURED NEAR BRUCKÖY SOURCES FOR THE LOCAL AGRICULTURAL BUILDINGS SUMMARY: This research was conducted to determine the properties of lightweight aggregates of BrUCKÖY district and lightweight concretes made of this aggregate. It was also determined usage possibilities of these concrete in the construction for farm buildings at province. The Turkish Standards dealing with the subject were considered to determine the properties of aggregate and concrete. Lightweight concrete were produced with ten different cement content levels were 75 kg/m3, 100 kg/m3, 125 kg/m3, 150 kg/m3, 175 kg/m3, 200 kg/m3, 225 kg/m3, 250 kg/m3, 275 kg/m3 and 300 kg/m3. In addition to suggested concrete making reguirements, to obtain a reasonable workability of this material a constant level of slump (approximately 5 cm) was achieved. The properties such as unit weight, water absorption, compressive strength, splitting tensile strength of lightweight concrete were determined. According to the obtained values; suitable lightweight concrete can be produced which will provide structural materials better than conventional materials in the province which are already in use. This conclusion can be drawn from the results that the high quality agricultural buildings that have a better thermal insulation and durability to eartquakes can be constructed economically at the province by using the natural lightweight aggregates that are available in this district.
