Özet:
The scope of this thesis is to discuss the use of structural lightweight aggregate. concrete and examine its potentials of utilization in Türkiye. The methods of production, the types, and the characteristics of lightweight. aggregates used for structural purposes are presented. Production and main properties of concrete made of these aggregates are surveyed. The unit price of this concrete is higher than that of normal weight concrete; however, the structures employing structural lightweight aggregate concrete may be economical if its advantages are fully utilized. Therefore, the economy of using this material is studied in detail. Types of structures which are likely to benefit most from using lightweight concrete are also reviewed. A general evaluation of investment is made. The availability of raw materials and the appropriate types of structural lightweight aggregates for Türkiye are discussed.
