Data for: Preparation and Mechanical Properties of Magnesium Phosphate Cement for Rapid Construction Repair in Ice and Snow

Description

A small amount of light burnt magnesia (LBM) partially replaced dead burnt magnesia and ice particles completely replaced mixing water to prepare MPC at a negative temperature.When the LBM/M ratio is 2%–4%, 4%–6% and 8%–12% at –2 ± 2 ℃, –10 ± 2 ℃ and –20 ± 2 ℃, respectively, the 2-h compressive strength of the MPC reached 20 to 40 MPa. When the ambient temperature returned to a normal temperature, the 28-day compressive strength of the MPC that was prepared at –20 ℃ reached ~70% of that of the MPC that was prepared at a normal temperature because of the secondary reaction of MPC and the growth of struvite.
