The working mechanism of MHEC as water retention agent in cement relies on two separate effects: first, its water sorption capacity and second the formation of hydrocolloidal associated 3D polymer networks. At low MHEC concentrations (≤ 6 g/L which corresponds to a dosage of 0.32% bwoc), water sorption presents the main mechanism for water retention while above this concentration, the first mechanism is supplemented by the formation of associated polymer networks which are highly effective in
