c) Added the regulations on components (see 4.1);

d) The technical requirements for Portland cement clinker, steel slag, granulated blast furnace slag, gypsum and grinding aids have been changed (see 4.2.1, 4.2.2, 4.2.3, 4.2.4, 4.2.5, 4.2.6, 4.1, 4.2, 4.3, 4.4, 4.5 of the 2006 edition);

e) Increase the limit and determination method of chloride ion (see 6.1.2, 7.1);

f) Added the limit and determination method of water-soluble chromium (VI) (see 6.1.3, 6.2.5);

g) Added the limit and determination method of alkali content (see 6.1.4, 7.1);

h) Change the regulations on final setting time (see 6.2.2, 6.3 of the 2006 edition);

i) Change the stability regulations (see 6.2.3, 7.6, 6.4, 7.4 of the 2006 edition);

j) The 3d compressive strength and flexural strength indicators of each strength grade have been changed (see 6.2.4, 6.5 of the 2006 edition);

k) Changed the factory inspection items and judgment rules (see 8.2.1, 8.3.1, 8.2 of the 2006 edition);

l) The requirements and judgment rules for type inspection are added (see 8.2.2, 8.3.2);

m) The requirements for product quality certification materials have been added (see 8.4);

n) Changed the inspection report regulations (see 8.5, 8.4 of the 2006 edition);
