In the research, C25/30 and C30/37 class ready-mixed concrete (RMC) produced in Eskişehir in
2022 of the compressive strength test results of concrete specimenstaken statistically. The concrete quality was
attempted to be evaluated by the C25/30 and C30/37 concrete classes created in different construction sites and
building sections in Eskişehir using the results of the compressive 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 214R-11 and TS EN 206. In the investigations,
the information from the same strength classes that were poured in Eskişehir and different provinces in Turkey
on various dates was compared and reviewed.
