1978: French mi Margar chuan China ramah structural adhesive (Sicaduer 31# adhesive) a rawn keng a.
1980: Ministry of Construction chuan official takin research project "Research and Application Technology Promotion of Building Structural Adhesives" tih chu a tichhuak ta a ni. Chinese Academy of Sciences-a Dalian Institute of Chemical Physics leh Liaoning Building Science Research Institute te chuan tangkawpin he project hi an buaipui a, kum 1983 khan an zo ta a, China rama practical building structural adhesive-JGN type-China rama chemical reinforcement hmahruaitu hmasa ber an siam a, domestic steel-bonded reinforcement of buildings lama gap awm chu an luah khat a ni.
1990: China Engineering Construction Standardization Association standard "Technical Specification for Strengthening Concrete Structures" (CECS25:90) chuan official-in steel-bonded reinforcement technology chu specification-ah a dah lut a, JGN series building structural adhesives chu designated product-ah a dah a ni. Chinese Academy of Sciences-a Chemistry Department leh Ministry of Urban and Rural Environmental Protection-a Science and Technology Bureau chuan "Appraisal Certificate for Building Structural Adhesives and Their Application Technology" chungchangah hriattirna an tichhuak.
1996: Market mamawh chhanna atan Chinese Academy of Sciences chuan structural reinforcement adhesives hrang hrang a zawnin a siam chhuak a, chung zingah chuan dynamic load-bearing components atan te, humid environment atan te, concrete surface siamthatna tur te, high-temperature condition atana hman tur te, leh injection molding atana hman tur te pawh a tel.
1997: Application survey leh practical experience zau tak atanga a lan dan chuan chemical steel bonding reinforcement chu reinforcement technology-ah chuan a langsar ber a ni. A kalphung chu a thiam hle a, technology pawh a puitling chho zel a, a thatna a pe a, chu chu sak awlsam, technology rintlak, hnathawk, material, leh hun senso tlem, leh hmun save te hi a ni. Structural designer te hnen atangin hriat hlawh chho zel a ni.
2000: Structural adhesives chu building thar leh hlui tan pawh reinforcement project-ah rang takin a zau chho a, chung zingah chuan concrete rebar anchoring, chemical steel bonding, chemical anchor reinforcement, carbon fiber cloth (plate) bonding, impact leh abrasion resistance, crack grouting, corrosion venna, leh waterproofing te pawh a tel. Construction industry-a building reinforcement material pawimawh leh pawimawh tak a lo ni ta a ni.
2006: National standard Code for Design of Strengthening Concrete Structures GB50367-2006 hman a ni a, hei hian China socialist modernization tihhmasawn kawngah nghawng tha tak a nei ngei ang.
