Block copolymers as dispersants for alkali-activated binders
A block copolymer for use as a dispersant for mineral binder compositions, containing an alkali activating agent. The block copolymer includes at least one first block A and at least one second block B, the first block A containing a monomeric unit M1 and the second block B containing a monomeric unit M2. A proportion of monomeric units M2, if any, in the first block A is less than 25 mol %, in particular less than or equal to 10 mol %, relative to all the monomeric units M1 in the first block A, and a proportion of monomeric units M1, if any, in the second block B is less than 25 mol %, in particular less than or equal to 10 mol %, relative to all the monomeric units M2 in the second block B.
