EFFECTS OF CHEMICAL ADMIXTURES ON SPECIALITIES OF HARDENED CONCRETE USED IN READY CONCRETE PRODUCTION IN ESKİŞEHİR

Abstract

In this study polls were taken from different ready mixed concrete firms in Eskişehir. Chemical admixtures used in concrete production were investigated according to the polls, and some information about chemical admixtures was obtained. Compressive strengths of concrete specimens manufactured by ready mixed concrete firms were evaluated, and results were investigated due to different types and proportions of admixtures used in concrete. Chemical admixtures were compared to each other at the end of the investigation, and the results showed, chemical admixtures gain concrete different characteristics according to various environmental conditions. The past investigations showed that the differences between chemical admixtures were most occurred owing to environmental conditions (season, temperature etc.), and chemical admixtures were classified according to seasons by users.
