b) the proportion of blastfurnace slag as a target mean, reported to the nearest I % by mass;
c) the results of the following tests, relating to the material delivered:
1) compressive strength at either 2 days or 7 days as appropriate, and at 28 days (see clause 7);
2) initial setting time (see 8.1);
3) soundness (see 8.2);
4) chloride content (see clause 9).
A.2.2.3 First-aid neasures The following first-aid procedures are recommended.
a) In the event of eye contact, wash eyes immediately with copious amounts of clean water for a period of at least 15 minutes and seek medical advice without delay.
