ASCD Group has been created with an aim to develop advanced structural materials and composites for building applications through research, development and innovation (RD&I). At the same time the focus is on enhancing durability and sustainability of buildings. To address the durability issues materials & technologies that are more resilient towards various loadings and extreme exposure conditions are being developed. Some of these are multifunctional coatings, cathodic protection (CP), cathodic prevention (CPre), corrosion inhibitors, chemical admixtures, composite strengthening & grid confinement systems, hybrid rebar couplers and precast concrete joint systems. Whilst the sustainable materials for building structures are based on  agro-forestry wastes (such as hemp concrete), construction & demolition (C&D) wastes and industrial wastes (red mud, fly ash, slag etc.). The Group has adequate expertise along with active participation of young scientists & students supported by state-of-art test facilities.  The scientists in the ASCD Group also undertake various testing assignments & investigation works on health assessment of structures and repair, retrofitting and protection.
