Effect of polycarboxylic acid superplasticizer on sulphoaluminate cement based grouting material by Mingxuan ZHANG, Pengfei WANG, Tao YANG, Xiuru LIU, Changquan WU

“…The results show that: ① The mechanical strength of the material increases with the decrease of the water-cement ratio, and the maximum compressive strength at 28 d is 56.56 MPa; ② With the increase of polycarboxylic acid water reducer content, the setting time gradually extended, the fluidity gradually increased, and the compressive strength showed a trend of first increasing and then decreasing, with the maximum compressive strength of 75.09 MPa at 28 d; ③ According to the flower-time curve, the change of flowability with time can be divided into four stages: rapid stage (Ⅰ), slow stage, rapid stage (Ⅱ) and stable stage, and the best grouting period is in the slow stage; ④ The addition of polycarboxylic acid superplasticizer will delay the hydration process of cement, but at the same time will make the structure and morphology of the generated hydration products better; ⑤ Slag∶desulfurization gypsum∶thioaluminate cement optimal mix ratio (mass ratio) is 4∶1∶15, the addition of 0.3% water-reducing agent to improve the flow can meet the requirements of underground grouting, while having high strength, the best grouting period is the slow period (20−100 min) under the current ratio. ⑥ According to the screening ratio and method, guide the field grouting reinforcement project of the 4204 working surface of Hemay No.3 Mine, confirm that the process has a good grouting effect, can fully fill the cracks and effectively strengthen the surrounding rock, and the maximum deformation of the top and bottom plates and two sides is reduced from 432 mm and 324 mm before grouting to 233 mm and 153 mm after grouting. …”
