Effect of Quality of Existing Concrete Structures in Ajdabia Region, Libya
In this research, the authors accomplished the statistical quality control of concrete. Data of 22 projects constructed by different companies have been randomly collected from Almetraka Laboratory for this research. Statistical analysis of the collected data has been completed according to ACI, BS and standards. This study reveals that the required average compressive strength fcr′ used in mix design of concrete, of the all projects except one, does not meet the specified compressive strength criteria according to ACI-214 criteria. For example, the standard deviation for Project No. 10 was 1.82, which is less than 2.8 for the excellent construction quality control of the concrete work according to ACI. Nevertheless, it is noted that the calculated value of a is 0.74 much less than 1.73 the approach one of the American standard. Therefore, implemented compressive strength of the concrete had been disapproved. Finally, based on the sustainable performance criteria recommendations had been made to Ajdabia Municipality’s decision makers.
