Example Embodiment
[0021] Example 1: The ratio of cementitious material is 50% cement and 50% phosphorus slag powder, 1% sodium sulfate and 2% desulfurization gypsum activator are mixed with cementitious material, and the water reducing agent is 0.25% of cementitious material % wood calcium, the amount of sand is 1:3 in the lime-sand ratio, and the consistency is controlled at 90-100mm of water, measured and stirred. The measured delamination degree of the mortar was 11mm, the 28-day compressive strength was 28.75Mpa, and the setting time was 860min.
