PLASTIC SPACER USED IN FIELD CONCRETE AND ITS GAINS

Abstract: Due to the development of technology and the expectations of mankind, changes in the classical reinforced concrete concept have been changing over time. There is a need to make new arrangements on building components due to reasons such as reducing construction cost, removing lighter concrete areas in reinforced concrete sections, using fewer raw materials, shortening construction period, designing sustainable and ecological conveying system and using factory production products. Plastic spacers one of the newest methods developed on construction elements have found various application areas for this reason. Especially in Scandinavian countries and Western Europe, these types of applications are seen in story slabs. In this study, the application principles, details and advantages of the plastic spacer formers developed for the field concrete poured in a thickness of about 20 cm on the ground will be mentioned. In the scope of the study, the results obtained from the loading experiments on specimen samples will be discussed. At the end of the study, it was observed that the use of the recommended plastic material to reduce the cost in the site concretes did not result in a decrease in the load-carrying capacities under design loads. It has also been observed that the plastic spacer used in the site concrete reduce the use of concrete by about 3-9%.
