Embodiment 1
[0039] An economical high-strength rapid-hardening grouting material, including ordinary Portland cement, rapid-hardening sulfoaluminate gelling agent and water. Among them, the water-cement ratio is 0.46:1, and the mass ratio of fast-hardening sulfoaluminate gelling agent to ordinary Portland cement is 0.67:1. The grouting material prepared with this ratio can meet the requirements for weak carbon Requirements for bearing strength required for grouting of calcareous siliceous sandy slate interbedded with thin layers of phyllite.
Embodiment 2
[0041] An economical high-strength rapid-hardening grouting material, including ordinary Portland cement, rapid-hardening sulfoaluminate gelling agent and water. Among them, the water-cement ratio is 0.46:1, and the mass ratio of fast-hardening sulfoaluminate gelling agent to ordinary Portland cement is 1:1. The grouting material prepared with this ratio can meet the requirements for weak carbon Requirements for bearing strength required for grouting of calcareous siliceous sandy slate interbedded with thin layers of phyllite.
Embodiment 3
[0043] An economical high-strength rapid-hardening grouting material, including ordinary Portland cement, rapid-hardening sulfoaluminate gelling agent and water. Among them, the water-cement ratio is 0.46:1, and the mass ratio of fast-hardening sulfoaluminate gelling agent to ordinary Portland cement is 1.5:1. The grouting material prepared with this ratio can meet the requirements for weak carbon Requirements for bearing strength required for grouting of calcareous siliceous sandy slate interbedded with thin layers of phyllite.
[0044] The preparation method of the grouting material of the present invention is: mixing the quick-hardening sulphoaluminate gelling agent and the ordinary Portland cement according to the proportion, and then adding water and mixing evenly. Among them, the water-cement ratio is 0.46, and the mass ratio of the quick-hardening sulfoaluminate gelling agent to ordinary Portland cement is (0.67-1.5):1.
