Liquid accelerator and preparation method thereof
The invention discloses a liquid accelerator and a preparation method thereof. The liquid accelerator is composed of the following components by weight percentage: 15-30% of aluminium hydroxide, 5-10% of sodium metaaluminate, 5-10% of sodium carbonate, 8-10% of magnesium sulfate, 5-20% of hydroxy carboxylic acid, 0.1-0.4% of defoamer, 1-10% of stabilizer and the balance of water. The liquid accelerator has rapid sprayed concrete setting time and obvious effect for the early strength and the 30-day compressive strength, is good in caking property, low in resilience value, simple in synthetic process, mild in reaction condition and excellent in performance and can realize the green environment-protection non-pollution construction. The effect is better than that of the market liquid accelerator.
