Abstract
The fluidity characteristics of cementitious compositions may be rapidly altered by the addition thereto of an aqueous dispersion of at least one comb polymer which comprises carboxylic moieties. The invention works especially well when the polymer is combined with an accelerator which is at least one of aluminium hydroxide or aluminium hydroxysulphate.
