Study on The Preparation and Performance of a New Alkali-free and Chloride-free Liquid Accelerator

摘要：

　　Accelerators have taken an important role in preparation of shotcrete.The preparation method of a new chlorine-free and alkali-free liquid accelerator was amplified,and its effects on cement setting time,mortar strength and other performances were studied.The results showed that the preparation accelerator was transparent liquid,alkali-free,chlorine-free,stabilization,and long time not to layer.When the addition ratio (in mass) of accelerator is more than 4%,such performances like setting time and mortar strength of cement reach the requirement of JC477-2005 standard.The 1d compressive strength of cement mortar was up to 14Mpa,and 28d compressive strength doe not decrease..The best addition ratio of this accelerator is 4% to 6%.
