Overview

Randomized trial investigates the impact of anionic polyacrylamide on magnesium phosphate cement materials, enhancing performance and workability.

Key Points

  • This study aims to evaluate the effects of anionic polyacrylamide on the properties of magnesium phosphate cement-based grouting materials.
  • Incorporated varying doses of anionic polyacrylamide (0–1.5 wt%) in magnesium phosphate cement.
  • Analyzed workability, mechanical properties, and microstructural characteristics with a water-to-binder ratio of 0.20–0.30.
  • Conducted systematic tests measuring fluidity, setting time, bleeding rate, compressive strength, flexural strength, and tensile bond strength.
  • APAM reduced the bleeding rate of the slurry and extended the setting time.
  • At 0.5 wt% APAM and a water-to-binder ratio of 0.25, fluidity was maintained at 250 mm while the setting time was 14 min.
  • 3-day compressive strength, flexural strength, and tensile bond strength reached 21.25 MPa, 5.41 MPa, and 2.71 MPa, respectively.
