This material, known as nanocellulose, which is made from nanostructured cellulose, has attracted attention in various studies because of its high mechanical strength and environmentally friendly properties. Its significant use in the construction industry as a mortar component to increase mechanical and physical strength is one of its most promising uses. This research aims to understand the synthesis of nanocellulose from paper waste using alkaline and mechanical synthesis methods. It also seeks to evaluate the strength of the mortar. The nanocellulose synthesis process begins by using an alkaline solution of NaOH and NaClO to break down lignin and hemicellulose from cellulose fibers. The synthesis results show that the resulting nanocellulose has particle dimensions ranging from 100–500 nm, with a needle-like morphology and excellent mechanical properties. The alkaline method at low temperatures provides advantages over conventional methods; it is more environmentally friendly. Characterization of nanocellulose using PSA and FTIR: In mortar applications, adding nanocellulose significantly improves its mechanical and physical properties. Slump Flow test results show flow values fluctuate depending on the cellulose content, with the highest flow value of around 160 mm observed in the control sampel (0% cellulose) and the lowest flow value of around 140 mm at 4% cellulose. The compressive strength of mortar with nanocellulose reached 30 MPa at 28 days for a concentration of 2%. FTIR, XRD, SEM, and EDX results also show improvements in the microstructure and interaction between nanocellulose and cement hydration products. This research indicates that nanocellulose from waste paper can be an effective solution for improving mortar quality, supporting the sustainability of the construction industry, and providing benefits in waste management.
