![]() Three types of nano cellulose showed diverse morphologies at 2000X, but CNF, CNC and MFC on cracks capably upgraded CTB’s strength characteristics. ![]() #Runix matrix stability crackAddition of NCMs to CTB well-inhibited crack propagations. NCM-reinforced CTB’s failure pattern was portrayed by tensile/shear failure. The cracks witnessed in CTB were created in the stress clouds after loading. The optimal concentration of NCM-reinforced CTB samples is 0.9 kg/m 3, and the strengthening effect of CNC on CTB is better than CNF and MFC. A two-aspect effect on UCS of CNF-, CNC–, and MFC-based samples was observed, namely an escalation followed by a reduction. The results are as follows: the addition of CNF, CNC and MFC to samples augmented its UCS values by 0.95 MPa to 1.39 MPa, 1.43 MPa and 1.29 MPa, respectively. Uniaxial compressive strength (UCS), cracking/failure patterns, deformation analysis, and microstructure of NCM-reinforced CTB samples were thoroughly explored. ![]() This study explores the quality of cemented tailings backfill (CTB) reinforced with diverse nano cellulose materials (NCMs) such as micro-fibrillated cellulose (MFC), hydroxylated cellulose nanofiber (CNF), and cellulose crystal (CNC) at macroscopic/microscopic levels. ![]()
