摘要
针对加气混凝土传统抹灰砂浆存在的保水性差、粘结强度低、易开裂空鼓等缺陷,研制了一种主要性能指标大大优于《蒸压加气混凝土用砌筑砂浆与抹面砂浆》(JC890-2001)标准的加气混凝土用新型抹灰砂浆,研究了保水剂、胶粉、膨胀剂等外加剂对砂浆性能的影响,并对各种外加剂对砂浆的改性机理进行了讨论。
To overcome the shortcoming of traditional masonry mortar for air -entrained concrete such as poor water retention, low bonding strength and liabititv to cracking, a new type masonry mortar for air-entrained concrete with better performance than that by JC890 -2001 standard was prepared. The effects of water-retentive agent, redispersible latex powder and expansive agent on masonry mortar were studied, and their modified mechanisms were discussed respectively.
