Statistical Evaluation and Comparison of Concrete Produced in Eskisehir with Concrete Produced in Different Provinces in Turkey

Abstract

In the research, statistical analysis of the compressive strength test results of concrete samples from C25/30 and C30/37 class ready-mixed concretes (RMC) produced in various concrete plants in Eskişehir in 2022 and poured in various construction sites and different construction sections (foundation and column, beam, slab) were made. The concrete quality was attempted to be evaluated in accordance with the C25/30 and C30/37 concrete classes created in different construction sites and building sections in Eskişehir using the results of the strength tests performed on a total of 1355 samples. The previous scientific studies were carried out within the framework of the statistical analysis of the compressive strength results of the C25/30 and C30/37 concrete class samples that were brought to the laboratory from various locations of different construction sites in Eskişehir, within the framework of the standards determined by the quality grades determined by ACI and TS EN 206. In the investigations, the information from the same strength classes that were poured in Eskişehir and different provinces in Turkey at various dates was compared and reviewed.
