| Abstract: | In this paper, through a large number of experiments an alkaline phenolicresin with better binding function and a kind of oxyanion which can cause the resin to hardenare developed. When KOH and hardeners are added into the resin, the satble binder informed. Instant strength and the final strength of the samples are increased after CO2 ispassed. |
