Now, the Vedanta Aluminium ltd’s lanjigarh refinery has become the first company in the world to develop cement free green concrete by using fly ash only.
The concrete is named as cold setting geo-polymer concrete due to its properties of fast setting in ambient conditions.
Speaking on the occasion, lanjigarh refinery COO and president Mukesh Kumar informed that they have developed a zero waste model around three years back and since then they are working in a number of projects related with waste utilisation to ensure optimum utilisation of natural resources.
The new technology has been developed in association with CSIR laboratory IMMT, Bhubaneshwar and in- house research, he informed.
The concrete is truly green concrete as water is required only at the time of preparing the mixture and thereafter no water curing is required, thus saving not only huge quantity of water but labour also as the concrete is stabilised in less than
6 hours only.
Kumar further informed that most of the cement concrete structures start deteriorating after about 20 years but the geo polymer produced can be more durable.
