This paper deals with modifying effects of hydroxyethyl methylcellulose on both fresh andhardened mortar. The results have shown that the addition of hydroxyethyl methylcellulose signifi-cantly enhances water retention of fresh mortar, reduces bulk density of fresh and hardened mortars,water adsorption of hardened mortar, compressive strength, flexural strength and elastic modulus tosome extent and hardly influences toughness of hardened mortar
