Abstract: From past few decades migration of humans from rural to urban areas has become a global phenomena and it has created pressure on concerned authorities for need for sustainable housing developments. This is because cities offer substantial reasons to keep coming back, such as jobs, entertainment, and amenities etc. Dense urban areas can be an equally viable and socially sustainable habitat if resources management is done on need basis. Horizontal growth has direct impact on natural resources and available land. In order to overcome the above said problems many countries had resolved by adopting tall structure technology from many of decades. So that area per person have decreased to greaer extent with minimum natural resources and embodied energy. In this case study, Monolithic concrete structure of 37 floors constructed at gopalpura, Bengaluru(India) is under consideration and technology adopted to make the structure durable and sustainable were revealed. Aluminium shuttering technologies were adopted to reduce the construction cycle time and cost. Systematic study is done to develop the Smart Dynamic Concrete by partially replacing ordinary Portland cement by Ground granulated blast furnace slag (GGBS)without compromising fresh and hardened properties of concrete and cycle time .Results showed that, use of ground granulated blast furnace slag and appropriate quantity of combination of Polycarboxylate ether and Viscocity Modifying agents enhances the flowable property and long-term strength of concrete.
