43、stituents 5.1 Cement Cement shall conform to EN 197-1 or to a European Assessment Document. 5.2 Fly ash Fly ash shall be siliceous or calcareous fly ash conforming to EN 14227-4. NOTE Siliceous fly ash is a pozzolan and requires lime or a source of lime (e.g. cement) to produce a hydraulic reaction.

44、 5.3 Blast-furnace slag Blast-furnace slag shall be either ground granulated blast-furnace slag conforming to EN 15167-1 or partially-ground granulated blast-furnace slag conforming to EN 14227-2. NOTE Other constituents are normally necessary to enhance the hydraulic reactivity of slag. 5.4 Hydraul

45、ic road binder Hydraulic road binder shall conform to EN 13282 (all parts) or to a European Assessment Document. 5.5 Lime Lime shall be air lime conforming to EN 459-1, in form of quick lime or hydrated lime or lime slurry. 5.6 Soil Not less than 95 % of the soil shall pass the selected sieve from T

NOTE 1 Som

47、e type of soils may be pre-treated to adjust moisture content and/or flocculate clays, for example with lime. NOTE 2 Organic matter can reduce or prevent the setting and hardening process. Laboratory mixture design work will determine whether soil containing organic matter can be accommodated. The a

48、mount of organic matter that can be accommodated depends on the type of organic matter. NOTE 3 Soil containing or suspected of containing sulfur, sulfide or sulfate can result in expansion of the mixture. Laboratory mixture design work including resistance to water testing in accordance with this Eu

49、ropean Standard will determine if material with the potential to cause swelling can be accommodated. 5.7 Water Water shall not adversely affect the setting, hardening and performance of the mixture. 5.8 Other constituents Other constituents include aggregate, gypsum or other materials that are either necessary for or improve hydraulic reaction and or improve workability, traffickability or performance. 6 Mixture 6.1 General The mixture shall comprise constituents specified in Clause 5.
