Sika India has always remained committed towards ensuring a better future that addresses imminent challenges like climate change, ever increasing resource scarcity and energy consumption. Sika India strives to balance the incumbent ‘costs’ with the potential ‘gains’, both in terms of environmental and economical dimensions. In fact, Sika technologies and products strive to reduce the overall consumption of limited resources and emission of greenhouse gases. As a guiding principle, Sika is committed to sustainable development. The company participates in Green Building Initiatives, such as LEED in the US, Brazil and Italy, or DGNB in Germany. And now, Sika’s commitment to sustainable development gets further enhanced by the product sustainability approach.


Given the fact that concrete is the most used man-made material in the world it was imperative that Sika comes up with a solution that makes this unavoidable ingredient for growth, environment friendly. After all, cement industry is responsible for about 5% of the global carbon emissions, and also requires large amounts of water and aggregates to produce concrete.


As the first step towards this goal, Sika India introduces the sustainable production of concrete admixtures. These admixtures improve the performance of the concrete; make it more durable by improving water tightness, increasing corrosion resistance and sulfate resistance. They help to prolong workability time and improve high early strength development. Through life cycle analysis (LCA) it has been proven that usage of superplasticizer’s enhances concrete’s energy demand and CO2 balance by over 20%.


However, Sika’s superplasticizers range viz. "Sika ViscoCrete®", "Sikaplast" and "Sika Viscoflow" were all based on oil based Poly Carboxylate Ether (PCE). But not anymore!  Sika has developed a bio-based version of its concrete superplasticizers developed from renewable raw materials in lieu of oil.


This bio-based PCE superplasticizer is produced when polyethylene glycol is synthesized by a unique process using molasses, a by-product of sugar production. The success of this product can be gauged from the fact that the highest broadcasting tower and the second highest building in the world: 634 m high, the Tokyo Sky Tree is built using Sika bio-based concrete superplasticizers.


In the coming years, expect more such marvels built with Sika admixtures. Expect more such Sika products which gradually will make constructions not only more durable, but also energy-efficient eco-structures.


Presently, Sika India produces bio-based superplasticizers at its plants in Jhagadia (Gujarat) and Kalyani (West Bengal). The Jhagadia plant with a production capacity of 10,000 tonnes per annum was completed and commissioned on 8th April, 2016, and was ready for production on 17th June, 2016. The plant has already received an Environmental Clearance from the Government of India and will reduce the dependence of Western India and North India for PCE based Admixture.
