An experimental research into the use of basalt as reinforcement in concrete to reduce the ECI value of a concrete quay wall apron. In this research experiments with basalt minibars and basalt reinforced polymer rebars are performed to compare directly to steel fibres and steel rebars. With the test results 4 designs are produced resulting in material requirements per type of reinforcement. By using these amounts of material an ECI value is determined showing that in this research basalt is an option to reduce the environmental impact. The ECI value presented in this research are in euros/year lifespan, meaning that for a different lifespan the material shows different values. Here the pros of basalt come out as the material is resistant to corrosion as it is a stone like material. Therefore in this research with a product that is placed in water, the lifespan of a steel reinforced apron could only reach 50 years where the apron with basalt reinforcement reached 100 years.
