Sunanda bags award for its unique product

Sunanda Speciality Coatings Pvt Ltd bagged the award for the 'Development
of Anti-washout admixture' for the first time in the Indian subcontinent. This award was presented jointly by the Department of Chemicals and Petrochemicals GOI and FICCI at the hands of Surjit Kumar Chaudhary, Secretary, Department of Chemicals and Petrochemicals GOI. Chief Minister of Gujarat Anandiben Patel, Chief guest at the inauguration of India Chem function congratulated the winners, as an encouragement to indigenous R&D and innovation in the chemicals sector, which is thought to be one of the key stakeholders in making Prime Minister´s 'Make in India' programme a success.

Sunanda Company´s Chairman and Managing Director, Dr Surendra Manjrekar pointed out that concrete when poured under water will disintegrate as the cement gets washed away, resulting in concrete not setting. Typically over 90 per cent of the cement is washed away resulting in massive loss in terms of money, resources and poor quality of underwater construction. This novel anti-washout admixture for concrete was developed by Sunanda to be used for the underwater construction of a weir for the Srisailam Dam (India´s second largest hydropower project) across the Krishna River in Andhra Pradesh, India. Since there are no manufacturers of anti washout admixture in India, this development was significant involving over 100 trials. This admixture allows for construction to take place underwater with less than 8 per cent loss of cement and has the potential to revolutionize the construction of underwater structures like dams, bridge piers, jetties, weirs, canals, foundations etc.

Dr Manjrekar further added that primarily this breakthrough in anti-washout technology for the first time in India has made the construction of hydraulic structures sustainable. Hydraulic structures are of paramount importance for making India self sufficient in terms of energy, hydro-power projects, irrigation projects and so forth. The use of such anti-washout admixtures, has opened avenues for many applications in the construction industry in India wherever underwater concreting becomes necessary such as cases of seismic retrofit design and construction of bridges, tremie concreting to connect precast concrete pile caps, underwater repair of stilling basins, concreting for caissons, concreting for jetties, weirs, dams, canals, etc.

The company has also won 'Product Innovator of the Year 2012' and 'Product Innovator of the Year 2013'.
