NOVELTY - Strongly weathered limestone dangerous rock joint filling agent comprises component-A and component-B in the mass ratio of 4:1; where the component-A comprises 54-46 wt.% E-44 epoxy resin, 8.5-9.5 wt.% calcium lignosulfonate, 10.5-11.5 wt.% accelerator, 5-7 wt.% ethanol, 5-7 wt.% silicone micropowder, 8.5-9 wt.% graphene, and 14-15 wt.% resorcinol bisglycidyl ether; where the component-B comprises 37-38 wt.% cashew phenolic aldehyde(sic)/triethylenetetramine curing agent, 10-11 wt.% silicone coupling agent, 8-9 wt.% toner, 18-19 wt.% aluminum silicate powder, 14-15 wt.% titanium dioxide powder, and 9-9.5 wt.% antimony trioxide. USE - The filling agent is useful for filling and strengthening of strong weathered limestone joints in karst areas, and actively preventing the collapse of dangerous rock slopes by restoring the integrity of limestone rock mass. ADVANTAGE - The filling agent: is economical; and has convenient construction, and no organic waste gas and toxic gas will be generated during the preparation process, which is environmentally friendly and non-polluting. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the strongly weathered limestone dangerous rock joint filling agent comprising separately preparing component-A and component-B, mixing component-A and component-B in a mass ratio of 4:1 to obtain a strongly weathered limestone dangerous rock joint filling agent.
