Abstract
In our project, we have made a particular number of concrete specimens, some are containing carbon black with a specified percentage, and the others are without any carbon black at all, this carbon black is taken from waste tire pyrolysis process, and we have added this carbon black to concrete that is used in buildings, the PCB we used is without any chemical purification.
After we prepared the concrete cubes specimens, we have applied several tests on these specimens, the tests were applied on both, the specimens with carbon black with specified percentage, and the specimens that are completely without any carbon black, and this was done to compare between the results from both, and to check if the results are preferable or not, the tests were applied on the specimens after 7 and 28 days since making the specimens. The tests were used in our project are compressive test and this was to check the compressive strength before and after adding the PCB, friction test, and this was to check the loss in mass with time due to a friction load, water adsorption, and this test was applied to check if water adsorption increase or not, and the last was the slump test.
Generally from results we had, the compressive strength was increased, while the water adsorption was decreased, about the slump, results gave the minimum slump, from friction test results, we have noticed that the friction was minimum, looking to those results, using PCB with specified percentage gave a preferable results.
