INTRODUCTION

 In the wake of climate change & global commitments to bring down GHG emissions & march towards net zero sustainable development, it is high time, we take a leap from conventional construction practices & transit towards resource-efficient, climate-responsive, energy-efficient disaster-resilient materials, processes, systems & technologies. Cast-in-situ masonry/RCC construction using brick by brick/brick & sticks is being replaced globally by offsite construction wherein building elements can be produced under controlled conditions in a factory setup or casting yard and transported to the site for assembly & making the desired structure. These industrialized building systems are time-tested & proven around the globe & being practiced in the country also. The Indian construction industry is picking these practices slowly but surely. Therefore, Industrialized building systems are the future of Indian Infrastructure.

Also, to be developed nation by 2047, the rapid construction systems which reduce the construction time considerably are imperative & will replace the existing RCC framed construction. As regards materials, cement & steel are major ingredients of any construction but these materials are based on finite natural resources and therefore to be used optimally. Resource optimization in building material sector is key to sustainable development. Cement blended with supplementary cementitious materials (SCM) such as fly-ash, slag, GGBFS; materials based on renewable resources, waste, by-products; recycled/refurbished materials; green concrete, geo-polymer concrete; geo-polymer coarse aggregates; fly-ash to sand; nano concrete aggregates; artificial sintered aggregates; manufactured sand; slag sand; FRP/GFRP steel bars, fibres replacing rebars are few in the future list of materials. Smart materials, materials with less embodied energy & eco-labelling of materials is the vision for futuristic materials.
