• Ultrafine cement, ultrafine fly ash, ultrafine slag, and additives (superplasticizer, AUA, gypsum, and retarder) are used to develop highly efficient composite ultrafine cement (CUC). • Rheological properties, chemical compositions, microstructure characteristics, and mechanical properties of CUC grouts are presented. • The new high-efficiency CUC grouts are used to reinforce the broken surrounding rock and to confirm that grouting can effectively reinforce the surrounding rock.
