45、y ground granulated blast furnace slag Ground or partially ground granulated blast furnace slag shall comply with EN 14227-2. NOTE Depending on the soil type, it may be possible to use granulated blast furnace slag complying with EN 14227-2 that has not been ground, although the user should be aware
46、 that mixtures containing such slag rely for their performance on crushing of the slag between soil particles under rolling which may not be achieved with some soil types. 5.2 Soil Not less than 95 % of the soil shall pass the 63 mm sieve when tested using wet sieving in conformity with EN 933-1. Th
47、e soil shall conform to classification and homogeneity requirements at the place of use. NOTE 1 Organic matter can delay the setting and hardening process. Laboratory mixture design work will determine whether soil/material containing organic matter can be accommodated. The amount of organic matter
48、that can be accommodated depends on the type of organic matter. NOTE 2 Soil containing or suspected of containing sulphates can result in expansion of the mixture. Laboratory mixture design work including resistance to water testing in accordance with this European Standard will determine if sulfate
49、s or other material with the potential to cause swelling can be accommodated. 5.3 Water Water shall not contain components that adversely affect the setting, hardening and performance of the mixture. 5.4 Other constituents Other constituents shall include lime in conformity with EN 14227-11, cement in conformity with EN 197-1, aggregate, gypsum, ground or crushed air-cooled steel slag or other materials that are either necessary for setting and hardening of the mixture or to i
