Abstract : Understanding durability as an essential part of the quality of infrastructures has become self-evident. Permeability is probably the most influential property related to the durability of concrete infrastructures. In this paper, durability of self-consolidating concrete (SCC) and conventional concrete (CC) mixes containing different types of aggregates is investigated. Different types of aggregates including natural river sand and gravel and also crushed rock and sand in different ranges of water absorption and specific gravity were used in SCC and CC mixes that were prepared in water/powder and water/cement ratios of 0.42 and 0.47, respectively. The fresh properties of SCC were observed through slump flow time and diameter, V-funnel flow time and J-ring tests. Compressive strength, splitting tensile strength, and water permeability were measured in all SCC and CC specimens. It has been found that in a constant strength class, using aggregates with different properties has considerable effects on both workability and permeability of SCC and CC.
