成果简介	NOVELTY - Self-restorative concrete composition comprises cement as the primary binding agent, coarse and fine aggregates for providing strength and bulk, water to initiate the hydration process, super absorbent materials (SAMs), which are hydrophilic polymers capable of absorbing and retaining large quantities of water to facilitate the self-healing mechanism, where the SAMs which are hydrophilic polymers capable of absorbing and retaining large quantities of water. USE - Self-restorative concrete composition used in infrastructure projects such as bridges, overpasses, and dams, residential and commercial buildings for enhanced longevity, water management systems including reservoirs and canals, transportation infrastructure like railway sleepers and road (claimed). ADVANTAGE - The self-restorative concrete composition is eco-friendly, cost-effective, and capable of absorbing and retaining significant amounts of water, heal cracks and extend the lifespan of concrete structures, enhances durability, reduces maintenance costs, and promotes sustainability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing self-restorative concrete, which involves: a. using cement (e.g., Ordinary Portland Cement), aggregates (fine and coarse); b. combining the cement, fine aggregates, coarse aggregates, and SAMs in a dry state; c. mixing thoroughly to ensure uniform distribution of SAMs throughout the dry components; d. gradually adding water to the dry mix while continuously mixing; e. allowing the SAMs to absorb water and swell during the mixing process, forming localized reservoirs of moisture within the concrete matrix; f. continue mixing until the concrete achieves a consistent and homogenous texture; g. avoid overmixing, which could degrade the SAMs or affect their water retention capacity; h. pouring the prepared concrete mix into molds or forms designated for structural elements, such as beams, slabs, or precast units; i. using proper compaction techniques to eliminate air voids and ensure uniform density; j. curing of the concrete wet curing by covering the concrete with wet burlap or similar materials to retain moisture, or optionally maintaining a controlled environment with ideal humidity and temperature conditions, ensuring optimal performance of the self-restorative mechanism; k. allowing the concrete to cure for the specified period, typically 28 days for full hydration; and l. monitoring for activation of the self-healing process and evaluate performance parameters such as crack healing efficiency and compressive strength.
