The comparison of the strength of the central exit and site inready C 20/25 and C 25/30 ready mixed concrete (Adıyaman sample)

In this study, the comparison of the strength of the central exit and site inreadyC 20/25 and C 25/30 ready mixed concrete is carried out. With this aim in mind,firstly sample was taken from transit mixer in the plant and the tempreture ofthe fresh concrete heat, slump were measured and sample were prepared forpressure endurance test. The same procedure was repeated under sitecircumstances and the distance between the central and site was recorded asendurance distance, besides the central and the site environment temperaturewere noted.In the samples taken, in the central three 7 days old and three 28 days oldtotally 6, for site in ready three 7 days old, three 28 days old totally 6 and three7 days old three 28 days old totally 6 compression test sample were prepared.Asexperiment sample 150 mm x 150 mm cubes were used.At the end of the experiments, during the slump experiments performed undercentral and site circumstances slump loss was observed in the central and siteconcretes. In the central exit and site inready concretes there obsereved anincrease of strength , between central exit and site inready concretes andconcrete left under site circumstances there observed a decrease in strength.viScience Code : 2251101Key Words : The site, Concrete compressive strength,Concrete quality controlPage Number : 75Adviser : Asst.
