The main factor that is indirectly proportional to permeability is durability. Concrete durability depends largely on the ease (or difficulty) with which fluids (water, carbon dioxide, oxygen) in the form of liquid or gas can migrate through the hardened concrete mass since concrete is a porous material. The consistency and accuracy of permeameter in producing results is of utmost important. This research is to determine the reliability of UTP Air Permeameter that has been developed in the concrete technology laboratory of UTP since there is no verification of the reliability of this test method compares other test methods. This project establishes the respond of UTP Permeameter on concrete samples age 3, 7, 28 and 56 days. Besides that, it also established correlations results obtained from UTP Permeameter and other tests method. Concrete samples were cast based on four different grades, which is grade 30, 40, 50 and 60. From this, the samples were moulded into slab and cube. Compressive strength tests was conducted on cube samples while UTP Permeameter test was conducted on slab samples which were cored into cylindrical cube. In conclusion, this project had accomplished its objective. From the correlation of the data obtained, the UTP Air Permeameter is a reliable device. Further laboratory test can be carried out by setting up different values such as different pressure or different grades.
