Abstract

The quest for advanced construction materials with improved performance characteristics has led to the exploration of innovative additives that enhance the properties of cement-based composites. This study investigates the integration of thermo-responsive poly (N-isopropylacrylamide) (PNIPAM) hydrogels into cement paste formulations to address common challenges such as workability and shrinkage. PNIPAM hydrogels exhibit unique temperature-sensitive properties, which can be harnessed to modify the rheological behavior and dimensional stability of cement paste. The research demonstrates that incorporating PNIPAM hydrogels significantly improves workability by reducing the viscosity and increasing the flow ability of the cement paste. Moreover, the hydrogels effectively mitigate shrinkage, thereby enhancing the dimensional stability of the hardened cement paste. Experimental results reveal that the thermo-responsive nature of PNIPAM hydrogels enables a self-regulating mechanism that adjusts paste properties in response to temperature variations during curing and service. These findings offer a promising approach for optimizing cement paste performance, with potential applications in various construction environments where temperature control and material stability are critical. The study highlights the transformative potential of PNIPAM hydrogels in advancing the functionality of cement-based materials, paving the way for more resilient and adaptable construction solutions.
