Designing sustainable concrete on the basis of equivalence performance: assessment criteria for safety
conference paper
In order not to hampers innovations, the Dutch National Building Regulations (NBR), allow an
alternative approval route for new building materials. It is based on the principles of equivalent
performance which states that if the solution proposed can be proven to have the same level of safety,
protection of health, energy efficiency and protection of the environment, it is accepted as well.
The framework of equivalence performance has been worked out in this paper with respect to
safety. Three types of assessment criteria have been derived: for individual vales, for characteristic
values and for relationships. More than one assessment criteria can apply at the same time. An
example for a new material containing 50 % of recycled concrete and 50 % of recycled sand-lime
brock aggregates illustrated the consequence of the assessment for two properties: compressive
strength and tensile strength.
The assessment procedure provides a new route for fast incorporation of new concrete-like materials
in construction without compromising the safety of the structures. This will not only stimulate
innovations. Since it is expected to be applicable for many newly developed green materials, it also
make a significant contribution to reduction in CO2 and energy consumption as well as raw materials
in a relatively short time.
