Abstract:
The use of concrete composites with textile waste provides a sustainable path for circular construction. This paper reports the effects of the incorporation of textile-derived cellulose on the performance of cementitious composites. The study investigated the effect of the substitution of cement with micro-cellulose, 0 to 5%, on the compressive strength of cement paste. Isothermal calorimetry revealed cellulose delays initial hydration and increases the cumulative heat release over time. Chemical and microstructural analytical techniques like Thermogravimetric analysis, Nuclear Magnetic Resonance, Mercury Intrusive Porosimetry, and Scanning Electron Microscopy were employed to examine the reaction kinetics of the cement when incorporating recycled cellulose. The research findings highlighted that recycled textile cellulose notably impacts the cement paste hydration process and the properties developed. Optimal cellulose content was identified as 1% by cement weight.
