摘要：
An early strength agent applied to liquid alkali-free setting accelerator was synthesized at 60 degrees C-70 degrees C by taking methacrylic acid, silicic acid, calcium hydroxide, and hydroxyethyl ethylenediamine as the raw materials. The experiment showed that after 4% early strength agent was added into the accelerator, the 1d compressive strength and 28d compressive strength of the quick-setting mortar and shotcrete were obviously improved, so the industrialized application of this early strength agent can be realized.
