2 The Dutch are Setting Standards CUR aanbeveling 116 and BRL 2507 CUR aanbeveling 116 is a Dutch guideline that came into force in October 2012 and treats the subject of IBAA specifically. It defines the use of IBAA as normal weight aggregate in reinforced and non-reinforced concrete structures. The application in pre-stressed concrete is excluded. The guideline allows for the replacement of natural sand and/or gravel in the following quantities: ppup to 20 Vol.-% in reinforced concrete and p pup to 50 Vol.-% in non-reinforced concrete and non-structural concrete products. In accordance with this guideline, IBAA can be used in strength classes from C 12/15 up to C 30/37. Also, IBAA is permitted in reinforced concrete of all exposure classes excluding XA2 and XA3. For use in exposure class XF, the replacement percentage is limited to 20 Vol.-%. The use of cement types CEM III/B and CEM II/B-V is mandatory for the environmental classes XD and XS. For non-reinforced concrete and concrete products, the CUR aanbeveling 116 permits the use of IBAA in all strength and environmental exposure classes. The matching BRL 2507 Evaluation guidelines for the KOMO product certificate AEC granulate as additive for concrete was introduced in October This regulation allows the production of standardised concrete and concrete products with IBAA under the KOMO certification. Innovation made by granova The first in the Netherlands to market IBAA for the high quality application of concrete is the REMEX subsidiary HEROS Sluiskil B.V. The plant processes around 700,000 tonnes of MSWI bottom ash per year. Due to significant research and development efforts and relevant investments into plant technology the ash is turned into a high quality building material that complies with the new Dutch regulation. The final material is produced and delivered with the according CE and KOMO certificate and marketed under the brand name granova. granova is not only the sustainable and financially attractive alternative to primary aggregates it also offers a real competitive edge to concrete producers The REMEX Dutch processing facility, operated by its subsidiary HEROS Sluiskil B.V

3 Aggregate for Concrete Can Incinerator Bottom Ash Aggregate (IBAA) be used in concrete? There is a set of standards that provides the framework for all European countries that wish to use secondary aggregates in concrete or concrete products. But the first country to address IBAA in separate national guidelines is the Netherlands. EN 12620: Aggregates for concrete in accordance with EN The European standard EN specifies the properties of normal weight ( 2 t/m³) aggregates and filler aggregates for use in concrete according to EN It covers aggregates obtained by processing natural, manufactured or recycled materials and mixtures of these. Thus, it also applies to industrial by-products like IBAA. EN for lightweight aggregates does not apply to IBAA. EN provides information concerning the specification, performance, production and conformity of concrete. It is amended with complementary national standards and guidelines. EN applies for structural concrete in situ (ready mixed), for precast structures and structural precast products for buildings and civil engineering works. The standard is not mandatory for concrete products.

4 Specification of concrete The requirements concerning the con - crete mix design and its constituents are dependent on the concrete s specification. For concrete designed in accordance with EN 206-1, for example, this includes parameters like concrete strength and exposure to environment. The strength class is a measure for the compressive bearing capacity of concrete. An excerpt from EN with some common strength classes is given in Table 2. Table 2: Example of strength classes according to EN Compressive strength class Minumum characteristic cylinder strength [N/mm 2 ] C 8/ C12/ C16/ C20/ C25/ C30/ Minumum characteristic cube strength [N/mm 2 ] The exposure class is a measure of the exposure of concrete to attacks such as rain, freeze/thaw and chemicals. The standard differentiates six main groups (see table 3); a higher number behind the group letter indicates stronger exposure. What this means in practice can be seen in the graphics to the right. They show common exposure classes of structural elements in building and civil engineering construction. Table 3: Environmental exposure classes in accordance with EN Type of exposure Exposure class 1 No risk of corrosion or attack X0 2 Corrosion induced by carbonation XC 1, XC 2, XC 3, XC 4 3 Corrosion induced by chlorides other than from sea water XD 1, XD 2, XD 3 4 Corrosion induced by sea water XS 1, XS 2, XS 3 5 Freeze/thaw attack with or without de-icing agent XF 1, XF 2, XF 3, XF 4 6 Chemical attack XA 1, XA 2, XA 3 Examples of exposure classes: Industrial construction (top) and civil engineering works (bottom)
