For the design of a basement parking construction in Rotterdam (The Netherlands), the constructor has to work with a crack width of 0.10 mm based on the watertightness requirements. Traditionally, the amount of (shrink) reinforcement is determined based on this requirement. As an alternative, another calculation has been made, now with a concrete mixture that has been modified with the Basilisk Self-Healing Agent. Due to the Self-Healing properties of this mixture (which will seal cracks autonomously), a crack width of 0.17 mm can be used for this project, resulting in less reinforcement. The savings in reinforcement is achieved because the constructor can calculate the design based on the durability requirements. After all, the Self-Healing Agent closes cracks, so that watertightness requirements are no longer normative.
In this example, concrete with the Self-Healing Agent reduces 27 kg/m³ of shrinkage reinforcement (steel) and leads to a decrease in the Environmental Impact score of 19.3%. This way, Basilisk Self-Healing Agent provides an important contribution to a more environmentally friendly concrete.
