STATISTICAL ANALYIS OF READY MIXED CONCRETE IN ANKARA

At this study, statistical analyzed the results of the compressive strength tests with two different concrete class in Ankara, by testing the C20/25 and C25/30 ready mixed concrete samples which poured in different construction sites in 2016. Based on the results of the compressive strength of a total of 3012 samples, a statistical analysis was carried out and the quality of the ready-mixed concrete in Ankara was tried to be determined. It was determined that the compressive strength results of the samples that C20/25 and C25/30 classes brought to the laboratory from various construction sites in Ankara showed some differences in terms of the standards. All samples were analyzed by ACI (American Concrete Institute) and evaluated according to TS EN 206 standards. In addition, previous studies were examined and some information was given about new building control system
