- Abstract
With aluminum sulfate and modified three-ethanolamine as main materials and citric acid, tartaric acid, EDTA disodium and phosphoric acid as auxiliary materials, a new fluorine-free alkali-free liquid accelerator was prepared by single component test and orthogonal test.The setting time and 1 d compressive strength were determined. The results showed that when the solid breaking parameter of liquid accelerator in reference cement was 2.8%, the initial setting time was 2 min27 s, the final setting time was 6 min30 s, the compressive strength of 1 d was 9.67 MPa, and the pH value was 2.20. At the same time, the liquid accelerator also showed good adaptability to several engineering cement.
