A Statistical Study On Ready-Mixed Concretes Produced In Eskişehir After The 1999 Earthquake

Yıl 2005, Cilt: 18 Sayı: 1, 75 - 87, 30.06.2005

In this study the compressive strength results of samples, which have been taken from concrete produced in ready-mixed concrete facilities in the province of Eskişehir and its vicinities after the earthquakes of 19th August and 12th November, have been statistically evaluated. Ready-mixed concrete facilities belonging to three different plants and results of Concrete Laboratory of Osmangazi University Civil Engineering Department have been evaluated separately for the years 1999, 2000 and 2001, and the results have been discussed according to the variability coefficient given by ACI (American Concrete Institution) and criteria of TS 500/1984 Standard with respect to concrete quality. To this extent, concrete compressive strength results of 3910 samples, 1909 of which are for 7 days and 2001 of which are for 28 days, have been evaluated. Average compressive strengths (fcm), standard deviations (σ) and variability coefficients of the samples have been found and the results have been examined with respect to their compliance with TS 500/1984 and ACI criterias. By evaluating the available data we have tried to have an idea about the quality and reliability of concrete produced in Eskişehir after the earthquake.
