Abstract:

In this study, mechanical properties and durability of water-cured concrete samples composed of Nano Carbon Black Powder, at the dosage of 450 kg/m3 of cement with four different mixing ratios at %2, %4, %6 and %8 of Nano Carbon Black Powder replaced with the indicated percentages of cement, used for the production of concrete were investigated. In order to prepare the concrete samples, three different mixing methods were applied, of which the durations are 300, 480 and 600 seconds respectively. 50% of the samples were cured for 7 days, while the other half experienced the same condition for 28 days. Compressive strength, pressurized water permeability, and ultrasound transient velocity test employed on the samples were produced by these methods. Introducing the thesis, theoretical basis, and materials and methods are presented. Experiments carried out on the Nano Carbon Black, mix design, and concrete aggregate, and the Comparison Method used for evaluating the results are included in the methodology. Classical method, direct measuring, pressurized water permeability methods were utilized for compressive strength, ultrasound transient velocity, and the measurements respectively. In the fourth part of the thesis, the conducted experiment is summarized, and the results are presented. Lastly, the results and suggestions are in the fifth part. According to the results of the experiment, all of the concrete groups are in the structural concrete class. Considering all groups of concrete samples, the best results in both the compressive strength, and the pressurized water permeability tests have been observed the sample group containing %4 of Nano Carbon Black. In addition, in SEM images waste material is seen to be dispersed among crystals of the concrete structure. A correlation appears to exist between the obtained results and an increased compactness.
