Circulating fluidized bed slag reinforced modification method and application thereof

The invention discloses a circulating fluidized bed slag reinforced modification method and application thereof. The method comprises the steps of preparing a reinforcing agent in advance, carrying out enhanced modification on CFB slag in a soaking or spraying manner, taking out the CFB slag after the modification is finished, and carrying out standing maintenance to finish the enhanced modification treatment of the CFB slag, wherein the reinforcing agent is composed of water and an alkaline substance. According to the invention, the volcanic ash activity of a silicon-aluminum component of the CFB slag and hydration characteristics of a calcium-sulfur component are fully utilized, a self-gelling reaction substance in pores is effectively excited by adding the reinforcing agent, and hydrated calcium silicate gel and an expansive product ettringite are generated to fill the pores, so that the internal structure of the CFB slag is improved, the crushing value is reduced, and the purpose of strengthening modifica
