Enhancing Concrete Performance with Innovative Additives for Improved Durability and Strength
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
HPMC is a non-ionic cellulose ether made from refined cotton after alkalization, using propylene oxide and methyl chloride as etherification agents, through a series of reactions; and MHEC is produced from refined cotton after alkalization treatment, using ethylene oxide and methyl chloride as etherification agents, after a series of reactions, because the storage and use risk factor of ethylene oxide is higher than that of propylene oxide, so The production technology and process requirements of MHEC are higher. There are fewer manufacturers and the price of MHEC is higher than that of HPMC.
