OIL SHALE SEMICOKE ADSORPTION INHIBITOR AND APPLICATION THEREOF IN CONCRETE PREPARATION

The present disclosure discloses an oil shale semicoke adsorption inhibitor and use thereof in concrete preparation. The adsorption inhibitor is prepared by the following steps: sequentially adding 50-52.5 weight parts of an anti-corrosion rheological agent, 5-20 weight parts of methanol, 0.5-2 weight parts of sulfonated melamine, 2-5 weight parts of EDTA, 20-30 weight parts of an organosilicon compound, and 5-10 weight parts of stearate into a mixing container, and performing stirring well. The anti-corrosion rheological agent is a microbead. The adsorption inhibitor solves problems of strong water absorption, high adsorption of a water reducing agent, etc. of oil shale semicoke, reduces the use amount of the water reducing agent in concrete production, and can also reduce power consumption during grinding, thereby realizing high-value resource utilization of the oil shale semicoke.
