Prof. Tankeshwar Kumar, Vice-Chancellor of CUH, extended heartfelt congratulations to the scholar, highlighting how such contributions align with the university's mission to foster cutting-edge research addressing real-world challenges. The paper delves into optimizing nutrient formulations to maximize the self-healing capabilities of bacterial mortar, a bio-engineered material designed to autonomously repair cracks, thereby extending structure lifespans and cutting maintenance costs.

This accolade not only celebrates individual excellence but also spotlights Haryana's central university as a hub for materials science innovation amid India's massive infrastructure boom.

Background on Central University of Haryana and Its Civil Engineering Department

Established in 2009 under the Central Universities Act, CUH in Mahendragarh, Haryana, has evolved into a key player in higher education, offering multidisciplinary programs with a strong emphasis on research. The Department of Civil Engineering, part of the School of Engineering and Technology, focuses on sustainable infrastructure, geotechnical engineering, and advanced materials—areas critical for India's development goals. 41

With state-of-the-art labs and collaborations with industry leaders, the department has produced notable research in earthquake-resistant structures and eco-friendly concretes. The award-winning work emerges from this vibrant ecosystem, where scholars like this PhD candidate, under seasoned faculty guidance, tackle pressing issues like urban durability in a climate-vulnerable nation.

CUH's commitment to the National Education Policy (NEP) 2020 integrates research with skill-building, preparing students for roles in faculty positions or industry R&D. This paper's success exemplifies how university research translates into practical solutions for national challenges.

Key Insights from the Award-Winning Paper

The paper meticulously examines how varying types and dosages of nutrients—such as calcium lactate, yeast extract, and urea—influence the self-healing efficiency of bacterial mortar. Through rigorous experimentation, the scholar demonstrated that optimal nutrient blends can achieve up to 80-90% crack closure in simulated conditions, far surpassing traditional mortars. 31

• Nutrient Type A (organic calcium sources) yielded 75% healing in 14 days.
• Higher dosages (0.5-1% by cement weight) boosted calcite precipitation without compromising initial strength.
• Comparative analysis showed 2-3x better performance over non-bacterial controls.

These findings provide actionable data for scaling bacterial mortar in real projects, emphasizing cost-effective nutrient selection to balance efficacy and economy. The research employed advanced techniques like SEM imaging and ultrasonic pulse velocity to quantify healing, setting a benchmark for future studies.

For civil engineering students eyeing research careers, such empirical approaches highlight the value of methodical testing, opening doors to research assistant jobs.

How Self-Healing Bacterial Mortar Works: A Step-by-Step Breakdown

Self-healing bacterial mortar, also known as bio-concrete or bacterial concrete, incorporates dormant bacterial spores (typically Bacillus subtilis or Sporosarcina pasteurii) and nutrients into the cement mix. Here's the process:

1. Mixing Phase: Spores and nutrients are blended with cement, sand, and aggregates. Bacteria remain inactive due to high pH and dryness.
2. Crack Formation: Micro-cracks (up to 0.8-1mm) develop from stress, load, or shrinkage.
3. Activation: Water or moisture seeps into cracks, lowering pH and hydrating spores.
4. Metabolic Response: Bacteria metabolize nutrients, producing calcium carbonate (CaCO3) via microbially induced calcite precipitation (MICP).
5. Healing: CaCO3 crystals fill and seal the crack, restoring integrity and preventing further deterioration.
6. Verification: Healed areas regain 70-100% original strength, confirmed via non-destructive tests.

This autonomous mechanism mimics natural biomineralization, making it ideal for hard-to-reach structures like dams or bridges. 21 22

Relevance to India's Construction Sector and Sustainability Goals

India's construction industry, valued at over $500 billion and projected to reach $1.4 trillion by 2025, faces immense pressure from rapid urbanization and climate change. Traditional concrete structures require frequent repairs, costing billions annually. Bacterial mortar addresses this by extending service life by 30-50%, reducing carbon emissions from cement production (8% of global CO2). 20

Initiatives like Smart Cities Mission and PM Gati Shakti benefit immensely, with pilot projects in highways showing 40% less cracking. Haryana, with its industrial corridors, stands to gain from local innovations like CUH's, promoting circular economy principles.

Stakeholders from NHAI to private builders praise the potential, though adoption lags due to standardization needs. This award accelerates awareness, positioning Indian universities as leaders in green tech.

Global and Indian Research Landscape in Bacterial Self-Healing Materials

Pioneered by Delft University in 2006, bacterial self-healing has gone global, with over 500 papers since. In India, institutions like NITK Surathkal (self-healing brick patent) and IITs have advanced applications. 40 29

• 2025 studies show cave-isolated bacteria enhancing healing by 44%. 20
• Bagasse ash integration improves eco-profile. 4
• Bacillus subtilis variants optimize for tropical climates.

CUH's nutrient-focused approach fills a gap, as prior works overlooked dosage precision. Multi-perspective views from academia (pushing scalability) and industry (cost concerns) enrich the field. For Indian colleges, this inspires interdisciplinary collaborations in biotech-civil eng.

Challenges in Implementing Bacterial Mortar Technology

Despite promise, hurdles persist:

• Bacterial Viability: Spores must survive mixing (pH 12.5) and dry storage; encapsulation via silica gel helps.
• Cost: Nutrients add 10-20% expense; CUH paper optimizes to minimize.
• Scalability: Field trials needed beyond lab; Indian standards (BIS) lag.
• Environmental Factors: Efficacy drops in acidic or high-salt exposures.

Solutions include genetic engineering for robust strains and govt incentives under Atmanirbhar Bharat. Expert opinions from IIT Delhi stress pilot demos in rural Haryana bridges. 24

CUH's work provides roadmap, emphasizing nutrient tweaks for Indian conditions.

Future Outlook and Innovations Ahead

Looking to 2030, bacterial mortar could capture 5-10% of India's repair market, saving Rs 50,000 crore yearly. CUH's insights pave for hybrid materials with nanomaterials or fungi. Govt reports project integration in National Infrastructure Pipeline.
