| Abstract: | The effects of monomer, crosslinker, and accelerator content on the mechanical property of seal-filling hydrogel material for building hermetic wall were analyzed through a series of single-direction compression experiments. Grey predication by GM(1,1) model was also used to analyze the persistent property of hydrogel material. The results showed that the elastic modulus and strength of seal-filling hydrogel increased, and the elastic tended to reduce with the growth of monomer and crosslinker content. In c... |
