GLW型复合外加剂的研制

Research on a Kind of Compound Additive Called GLW

针对普通砂浆用于加气混凝土抹灰时,存在保水性差、粘结强度低、易开裂空鼓等缺陷,研制了GLW型复合外加剂。结果表明,用GLW型复合外加剂配制的砂浆性能远优于普通砂浆,具有保水性能好、粘结强度高、折压比大、收缩值小等特点,适合加气混凝土的抹灰。

Owing to common mortar for aerated concrete with bad water retention, low bond strength, easy cracking and bulging, a kind of compound additive called GLW was developed. The result indicates the performace of the mortar with the compound additive GLW is much better than than of common mortar. This mortar fits for aerated concrete with features of good water retention, high bond strength, big compression ratio, small contraction value.
