"The technical explanation of how fly ash (30–35%) and GGBS (40–50%) can substitute cement is accurate and provides quantifiable, practical solutions."

"Wow, I really like the idea of PeerHive! 📚 It’s super relatable — I’ve spent way too much time digging through WhatsApp groups for notes. The Snap-to-Share and Resource Map features sound super convenient, and I love the gamification aspect; it…"

"The idea tackles a very relevant problem of urban heat and pollution, making it socially impactful."

"CalmConnect’s approach to mental health triage with AI is innovative and scalable. It can make a real difference in underserved communities."

"Community driven platforms often struggle with engagement how will you keep people active after sign up?"

"The proposed sustainable concrete mix is promising, but its success will depend on establishing clear local standards and quality control measures to ensure consistent performance across different construction projects."

"The solution is well explained; adding a diagram of the sensor network would make it more engaging."

"This is a very strong and timely idea — combining industrial by-products like fly ash and GGBS into concrete mixes could really help reduce both carbon emissions and construction waste. The points about practical barriers—lack of awareness,…"

"• The problem statement is clearly articulated, highlighting both the environmental impact of cement production and the underutilization of industrial by-products, which makes the case compelling."

"This can truly revolutionize local construction practices by bridging the gap between research and real-world application. Kudos to the team!”"

"Innovative and impactful addressing both environmental and economic challenges of the construction industry in one solution."

"This startup has strong potential to align with global sustainability and green building goals"

"A practical step toward greener infrastructure. Excited to see how this can be scaled for both small and large construction projects.”"

"The Student Fitness Network is a powerful concept because it transforms fitness from being an individual struggle into a shared journey. By integrating peer support, gamified challenges, and affordable local resources, it directly addresses the…"
