Abstract: Aiming at the lack of the traditional building materials and Air stopping technology in the practical application, using the method of adding air entraining agent and fiber material in high-water material to improve it, the microstructure analysis and the stress-strain curve test of the material are carried on, using pump delivery to rapid construct Air stopping in the practical engineering application is done. The results show that the SEM diagram reflects the fiber intersperse in the hardening structure, to enhance the toughening, and the air entraining agent was added to make a large number of bubbles in the material, so that the compressive failure mode was changed from brittle failure into ductile failure; the stress-strain curve reflects that the material has a high compression rate, compressibility is equal or greater than 15%; site measured, the maximum convergence between roof and floor is 245 mm, the maximum rib sides convergence is 205 mm.
