本文研究了湿拌砂浆专用外加剂中减水组分、保水组分、缓凝组分及引气组分对砂浆性能的影响,结果表明:保水组分和缓凝组分作为外加剂中最重要的组分,能大幅度提高砂浆的保水率和延长砂浆的开放时间;引气组分有利于改善砂浆和易性,减水组分起到降低砂浆水胶比(W/B)的作用。
In this paper, the effects of water-reducing component, water-retaining component, retarding component and air-entraining component on the properties of mortar were studied. The results show that the water-retaining component and retarding component are the most important among the admixtures Can greatly improve the water retention of mortar and extend the open time of mortar. The bleed air is beneficial to improve the workability of mortar and the water reducing component plays the role of reducing the water / rubber ratio (W / B) of mortar.
