Sažetak
Special concrete types made by special mix design and different additives are introduced with the aim to achieve optimal performance for each specific application. One such concrete is pervious concrete. Pervious concrete has an advantage over ordinary concrete in form of: reduction of the runoff water, improvement of water quality near pavements and parking lots and, in case of urban areas, reduction of heat island effect and traffic noise. However, high porosity causes significant reduction of its strength so the pervious concrete has limited application in highway pavement structures. Since there is a big amount of steel slag landfilled in Republic of Croatia, it would be interesting to use this waste material as an aggregate in pervious concrete pavements. The main goal of this paper is to find out the optimal mixture of pervious concrete prepared with available steel slags that is able to meet the requirements according to Croatian legislation. Compressive strength, tensile strength and dynamic modulus of elasticity of pervious concrete containing slag will be tested and compared with the same properties of commonly used pavement concrete. Based on test results, the guidelines for preparation of optimal pervious concrete mixture and its incorporation in pavements will be given.
