Every year, numerous buildings across the country are affected by natural calamities. In such a scenario, it is very important for builders and constructors to focus on the structural strength of a building while carrying out any kind of construction.

Like any other country, India too has faced a fair share of climatic adversities in the past. While natural calamities are a big concern, a significant proportion of the country?? infrastructure is incapable of withstanding even acts of nature such as heavy rains. Heavy downpours during June-July 2019 in Maharashtra, northern Karnataka caused several walls to collapse across the state resulting in severe loss of life and property.

According to the National Institute of Disaster Management, Government of India, as much as 59 per cent of land area in India is susceptible to seismic hazards or earthquakes. The country has witnessed some highly devastating earthquakes since the late 19th century which have had consequential effects on our buildings and infrastructure.

In such a scenario, it is very important for builders and constructors to focus on the structural strength of a building while carrying out any kind of construction activity. Some such activities include repair, restoration or seismic strengthening of dilapidated buildings. In a building strengthening guideline prepared by Dr Anand S. Arya, Professor Emeritus, Department of Earthquake Engineering, I.I.T Roorkee and advisor to the Ministry of Home Affairs, he enlists eight special materials that are best suited for building repair and strengthening projects.

Here?? the list of eight materials that are most suitable for repair, restoration and seismic strengthening of..

  • Non-shrink grout

  • Shotcrete

  • Epoxy resins

  • Epoxy mortar

  • Quick-setting cement mortar

  • Mechanical anchor

  • Ferrocement ??fibre concrete

  • Fibre reinforced plastic (FRP)

According to Dr Arya, cement and steel are the most common materials that are used for the repair and restoration of various kinds of buildings. If need be, an appropriate admixture can be added to the cement mortar or cement concrete mix, concrete mix to enhance some of their properties such as non-shrinkage, bond strength, etc. Some common steel products used for such construction activities include bolts, rods, angles, beams, channels, expanded metal and welded wire fabric. Rounds, sleepers, planks, etc. made of wood and bamboo are generally used for temporary support and scaffolding purposes.

Rounds, sleepers, planks, etc. made of wood and bamboo are generally used for temporary support and scaffolding purposes.

Non-shrink grout: This is a very suitable material for filling up cracks in masonry structures. Their specialty is that their volume does not decrease upon setting. These days, ready-mix non-shrink grouts are available in the market which comprises non-shrink grout cement, special sands and polymer. The role of the polymer in such mixes is to improve the adhesive and tensile strength of the grout.

Shotcrete: Shotcrete is a type of mortar or concrete mix with coarse aggregates which are not more than 10 mm in size. This type of cement mortar or concrete is sprayed directly to a concrete or masonry surface using compressed air. This mix is sprayed at high velocity through a jet nozzle which helps the shotcrete to produce a compact homogeneous mass on the surface. The process of manufacturing shotcrete is called ??hotcreting??and there are two techniques of shotcreting techniques of shotcreting:

  • Wet mix process

  • Dry mix process

The wet mix process involves water being added to all the ingredients of the mix before it enters the delivery hose. Whereas, the dry mix process requires the damp mixture of cement and aggregates to be passed through the delivery hose to the nozzle and water is added to the mix in the nozzle. Dry mix shotcrete is most applicable in the repair of concrete elements. In such applications, an apan appropriate epoxy adhesive is also used to assure proper strength between the surface of the damaged structure and the shotcrete mix. Apart from that, the use of shear keys can further ensure proper shear transfer between the existing layer and the new layer of concrete.

Epoxy resin: Epoxy resins are chemical mixtures with high tensile strength which serve as exceptional adhesive agents. Their composition can be changed as per requirement and the ingredients required to produce a suitable epoxy resin are mixed just before they are applied. The viscosity of some epoxy resins is so low that they can be injected into fine cracks as well. On the other hand, epoxy resins which have high viscosity are generally used for surface coating purposes and for filling large cracks or holes. These binding agents can also be effectively used in applications that require attaching steel plates to damaged structures.

Epoxy mortar: This special material is formed by mixing either high or low viscosity epoxy resins with fine aggregates/sand and is used to fill voids or gaps which are very big in size. The compressive strength and tensile strength of epoxy mortar are higher whereas its modulus of elasticity is lower than that of cement concrete. Sand is added while producing epoxy mortar to enhance its modulus of elasticity.

Quick-setting cement mortar: This is basically non-hydrous magnesium phosphate cement comprising a liquid and a dry powder. Quick-setting cement mortar is formed by mixing the liquid with the dry powder just like cement and aggregates are mixed to produce cement concrete.

Mechanical anchor: These are anchors or fasteners which provide anchorage to concrete or masonry structures by using wedging action. Mechanical anchors are used to provide sufficient strength to a structure and some anchors provide shear as well as tension resistance. For applications where mechanical anchors cannot be used, the use of chemical anchors which are attached to drilled pilot holes using polymer adhesives has been advised.

Ferrocement fibre concrete: This building material is applied as a comparatively thin layer of cement mortar over reinforcing materials such as mild steel rods having a diameter of 4.5 to 6 mm spaced at an interval of 75 mm from each other both ways and covered with 19 gauges, 11 mm opening square mesh on each side. The building technique used with this material is simple and can be executed by masons and unskilled labour. In the case of retrofitting applications, ferrocement plates are positioned at an appropriate location on the surface of the masonry structure and directly attached to it. The thickness of the plates can vary in the range of 30 to 180 mm.

Fibre reinforced plastics or polymers (FRP): This recently developed material can be used for the strengthening of reinforced concrete (RC) or masonry structures or as a replacement of steel plate bonding. The strength to weight ratio as well as corrosion resistance of FRP is high. Further, the weight of an FRP plate can be as low as 20 per cent that of a steel plate while it can be 2 to 10 times stronger than an FRP plate. These plates need to be attached to the affected structure using epoxy mortar and it is advised to refer to the manufacturer?? specifications and conduct proper tests before finalising the design of any retrofitting project.

ABB reconditions 25 drives at ACC’s Jamul cement plant, avoiding 16 tonnes of CO₂ emissions while improving reliability through predictive maintenance.
Chhattisgarh

ABB has signed a multi-year Motion OneCare service agreement with ACC Limited, part of the Adani Group, to modernise ageing industrial drives at its Jamul cement plant in Chhattisgarh, improving operational reliability while avoiding approximately 16 tonnes of carbon dioxide (CO₂) emissions without disrupting production.

Announced on 27 October 2026, the agreement combines scheduled drive reconditioning, digital condition monitoring and energy appraisals to extend equipment lifespan, improve plant uptime and optimise maintenance costs. The initiative marks a shift from conventional equipment replacement towards a more resource-efficient approach to industrial asset management.

The first phase, completed in April 2026, involved the on-site reconditioning of 25 ABB ACS800 variable speed drives without a major plant shutdown. By retaining the existing cabinets and restoring the drive modules rather than replacing entire panels, ABB helped ACC preserve capital investment, minimise material consumption and avoid approximately 16 tonnes of CO₂ emissions.

A second phase, covering an additional 25 ACS800 drive modules, is scheduled for the fourth quarter of 2026. The programme is designed to improve long-term equipment reliability while allowing maintenance activities to be aligned with the plant’s operational schedules.

The ACS800 drives, installed at Jamul in 2010, had delivered more than a decade of near-continuous service in demanding cement manufacturing conditions. However, ageing electrical components and changing fault patterns had begun to affect their ability to meet the plant’s reliability requirements.

Rather than opting for complete equipment replacement, ACC engaged ABB’s certified engineers to conduct a comprehensive asset health assessment. The evaluation found that the existing cabinets and enclosures remained structurally sound, making targeted reconditioning a technically viable and cost-effective alternative to full replacement.

Drawing on nearly two decades of experience with ACC’s equipment and operating requirements, ABB developed a maintenance framework tailored to the plant’s shutdown windows, budget cycles and production priorities.

The Motion OneCare agreement incorporates planned equipment restoration, condition-based monitoring and energy assessments, enabling ACC to adopt a more systematic approach to maintaining critical electrical infrastructure.

As part of the programme, ACC has implemented ABB Ability™ Digital Powertrain Insights to monitor drive performance and identify emerging operational issues before they result in equipment failures.

The digital platform provides continuous visibility into parameters such as temperature, current, vibration and fault patterns. These insights allow maintenance teams to detect early signs of equipment deterioration, schedule interventions more effectively and reduce the likelihood of unexpected downtime.

Amit Gupta, Local Division Manager, Motion Services, ABB India, said: “We know what unchecked wear costs over time: a small inefficiency that eats away at ROI for years. At Jamul, the evidence pointed clearly to assets with productive life still in them.”

“Our job was to restore them properly and give the team the tools to stay ahead of the next problem. At ABB, we don’t just fix what fails. We want to protect what works.”

The initiative also demonstrates the growing relevance of circular economy principles in cement manufacturing, where extending the service life of existing industrial equipment can reduce capital expenditure, material consumption and the environmental impact associated with manufacturing replacement components.

According to ABB, drive reconditioning can reduce lifecycle emissions by 50 to 80 per cent compared with complete equipment replacement. By preserving functional components and restoring critical modules, the process helps retain the economic and material value of existing industrial assets.

The addition of energy appraisals in subsequent phases will further expand the programme beyond equipment restoration, enabling ACC to assess drive performance, identify energy-saving opportunities and improve operating efficiency.

For cement manufacturers, variable speed drives play an important role in controlling motors and optimising energy consumption across production processes. Maintaining their reliability and efficiency is essential for minimising operational disruptions and managing electricity costs.

Vinod Bahety, CEO – Cement Business, Adani Group, said: “Moving from reactive firefighting to a structured maintenance plan was exactly what this operation needed. That kind of peace of mind doesn’t come easily. It comes from a partner that understands how your business runs.”

“We didn’t need a full system overhaul; we needed expert support, actionable insights, and a plan we could execute around our schedule. That’s what we got.”

The project supports ACC’s broader strategy to improve manufacturing efficiency through digital transformation, preventive maintenance and sustainable asset management.

ACC, a subsidiary of Ambuja Cements and part of the Adani Group, operates 20 cement manufacturing facilities and 119 ready-mix concrete plants across India. The company has been advancing initiatives focused on renewable energy, circular economy practices and technology-driven operational improvements.

Alongside Ambuja Cements, ACC is part of a large-scale building materials business committed to achieving net-zero emissions by 2050, with near-term and net-zero targets validated by the Science Based Targets initiative (SBTi).

The Jamul initiative aligns with these sustainability objectives by demonstrating how equipment life extension and digital monitoring can contribute to resource efficiency without requiring large-scale replacement of existing infrastructure.

ABB, a global technology company specialising in electrification and automation, brings more than 140 years of industrial expertise and employs approximately 110,000 people worldwide. Its Motion Services business supports industrial customers through equipment maintenance, modernisation, digital monitoring and lifecycle management solutions.

The agreement also reflects a wider shift in industrial maintenance practices, with manufacturers increasingly adopting predictive technologies to improve equipment availability, manage costs and reduce unplanned shutdowns.

With 25 drives already reconditioned and another 25 scheduled for restoration, ABB’s collaboration with ACC illustrates how targeted modernisation, digital monitoring and circular maintenance practices can extend the operational life of critical equipment while supporting more efficient and sustainable cement production.
