The compressive strength at 0 ℃ for 8 hours was ≥ 3.5MPa, the thickening time was adjustable, the pumping time was controllable, and the low-temperature strength developed rapidly. Observation elements include hydration heat, etc. A total of 30 indoor experiments were conducted, and the experimental dataset was fully open and shared. The indoor experiment of this project started on January 1, 2019 and ended on December 31, 2019. The resource coverage period is from September 20, 2017 to March 20, 2020, and the experimental site is in Beijing.
