IIT Indore's new eco-friendly cement-free concrete cuts costs by 20%, saves water
IIT-Indore is shaking things up in the construction world. Its civil engineering team, led by Associate Professor Dr Abhishek Rajput, has created a cement-free concrete using geopolymer technology. The result? A stronger, faster, and greener way to new concrete doesn't just perform better -- it could also bring down construction costs by up to 20% when local materials are used. Plus, it skips water curing altogether, which is a big win in times of water CEMENT, HELLO WASTE MATERIALSUnlike traditional concrete that relies on Ordinary Portland Cement (PCC), this new geopolymer high-strength concrete (G-HSC) uses fly ash and ground granulated blast furnace slag (GGBS) -- both industrial by-products. That means it's not just cement-free, it's waste-reducing too. Even better, this concrete can cut CO emissions by up to 80%, addressing one of the construction sector's biggest climate problems. Cement alone is responsible for about 8% of global CO emissions, releasing around 2.5 billion tonnes of CO every FOR URGENT PROJECTSWhat makes this concrete even more impressive is its speed. It gains over 80 MPa compressive strength in just three days, making it ideal for urgent builds like military bunkers, bridges, disaster relief structures, and railway or highway contrast, regular cement-based concrete usually takes 28 days to reach similar strength Suhas Joshi, Director of IIT Indore, called the project 'an excellent example' of how the institute is supporting India's green researcher Dr Rajput added, 'The goal is to find a practical solution that benefits both the environment and the construction industry.'- Ends

IIT Indore Develops Cement-Free Concrete That Cuts Carbon Emissions By 80%
In a significant leap toward sustainable construction, the Indian Institute of Technology Indore (IIT-I) has developed an eco-friendly, cement-free concrete that could slash carbon dioxide emissions by up to 80%, The Times of India reported. The breakthrough uses geopolymer technology and industrial waste materials like fly ash and ground granulated blast furnace slag (GGBS). Unlike conventional concrete, which relies on cement, a major contributor to carbon emissions, this new material eliminates the need for it altogether. According to the institute, the innovation not only reduces environmental impact but also slash construction costs by around 20%. "This development is a step toward transforming the way we build our future infrastructure as stronger, faster, and greener," TOI quoted Dr Abhishek Rajput, who led the research team, as saying. "The goal is to find a practical solution that benefits both the environment and the construction industry." One of the most promising features of this geopolymer concrete is its ability to gain strength rapidly, making it suitable for critical, time-sensitive construction like military bunkers, highway repairs, emergency shelters, and precast railway infrastructure. It also needs no water curing, a crucial advantage at a time of increasing water scarcity. Ordinary Portland Cement Concrete (PCC) currently accounts for about 8% of global CO₂ emissions, largely due to limestone processing and fuel consumption. Commenting on the significance of the development, IIT Indore Director Prof Suhas Joshi said, "This is an excellent example of how IIT Indore is contributing to national priorities through sustainable technology. Such developments align with India's vision for green infrastructure and carbon neutrality."

IIT-I creates environmentally sustainable concrete with industrial waste
Indore: Indian Institute of Technology, Indore (IIT-I), has created an environmentally sustainable concrete without cement using geopolymer technology, incorporating industrial waste products like fly ash and ground granulated blast furnace slag (GGBS). The institute said this innovative concrete can decrease carbon dioxide emissions by 80%, while reducing construction expenses by 20%. Additionally, it eliminates the requirement for water curing, which is particularly beneficial given current water scarcity concerns. The rapid strength development characteristic makes it ideal for time-sensitive construction applications, including military bunkers, bridges, emergency relief structures, precast railway sleepers, and highway pavement repairs. The research team, led by Dr Abhishek Rajput, associate professor from the civil engineering department at IIT-I, utilised geopolymer technology to produce high-strength concrete with superior performance and durability compared to conventional concrete. "This development is a step toward transforming the way we build our future infrastructure as stronger, faster, and greener. The goal is to find a practical solution that benefits both the environment and the construction industry," said Rajput. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Una forma más inteligente de protegerse contra la inflación eToro Market Updates Haz clic aquí Undo The institute noted that ordinary Portland Cement Concrete (PCC) is responsible for approximately 8% of global carbon dioxide emissions, generating nearly 2.5 billion tonnes of carbon dioxide annually through cement manufacturing processes, including limestone burning and fuel consumption.

Cops bust interstate arms racket, arrest 5 in city
1 2 3 Bhubaneswar: Airport police here on Friday unearthed a major interstate arms trafficking racket with the arrest of five men, including three from Uttar Pradesh and one from Madhya Pradesh. Police identified the accused as Prabin Kumar Singh (40), Abhishek Rajput (31) and Indrajit Singh (38), all hailing from UP's Ballia district, Raghvendra Singh (28) from Bhind district in MP, and Sheikh Sakil (28) from Salipur area in Cuttack district. "The operation was carried by our personnel in Pokhariput area, leading to the arrest of notorious illegal weapon traders and seizure of six illegal firearms, including four semi-automatic pistols and one revolver. We also seized 18 bullets from them," said police commissioner S Dev Datta Singh. Prabin Kumar, originally from Ballia in UP, had taken a house on rent near Jatni Gate area here about two months ago. He is mastermind of the gang, obtaining unlicensed weapons from various states, police said. The gang's forward and backward linkages are being investigated. "Abhishek, Indrajit and Raghvendra are his direct collaborators in the weapons distribution network. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Boots is giving free 75-minute hearing checks in Cramlington.

Initial investigation suggests the network has been sourcing firearms from eastern Uttar Pradesh and Bihar, and actively supplying them in Odisha and other states. "We are currently mapping their entire supply chain and identifying all possible connections. We are also conducting thorough background checks on the accused and investigating their potential links to other criminal activities," the police commissioner said. Police urged citizens to remain vigilant and report any suspicious activities related to illegal weapons. "Public cooperation is crucial in our ongoing efforts to combat such organised crime," he said. Follow more information on Air India plane crash in Ahmedabad here .
