| 摘要: |
| 研究了羟乙基甲基纤维素对新拌砂浆和硬化砂浆的改性效果。结果表明，羟乙基甲基纤维素明显提高了新拌砂浆的保水性，降低了新拌砂浆和硬化砂浆的体积密度，硬化砂浆的吸水率、抗压强度、抗折强度和弹性模量，对砂浆韧性改善不明显。 |

| Abstract: |
| This paper deals with modifying effects of hydroxyethyl methylcellulose on both fresh and hardened mortar. The results have shown that the addition of hydroxyethyl methylcellulose significantly 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 to some extent and hardly influences toughness of hardened mortar. |
| Key words: hydroxyethyl methylcellulose mortar modification |
