Description: Rapid construction technology which provides large built up space with minimal labor requirement while ensuring the requisite strength, structural integrity, durability, thermal and acoustic comfort is the order of the day. This is particularly required for developing housing solutions and for providing for the demand of commercial space in rapidly urbanizing India. Industrialized building systems in which components are prefabricated at site or in a factory and are assembled to form a complete structure with minimum in-situ construction, are destined to provide a solution to this multi-dimensional problem. The buildings constructed using this alternative method of construction have a shorter construction time with the additional advantage of labour saving. This proposal is developed considering this critical need. In this proposal, IIT Hyderabad (IITH) and Beardsell Limited are working together to test, evaluate and standardize the deployment of rapid construction technology using sandwich core panels with prefabricated reinforcement.

 

Project Title: Sustainable Engineered Cellular Geopolymer Masonry for Improved Building Envelope Performance

Agency: I-PHEE Program, Department of Science and Technology

Amount: Rs. 6,569,200 ($ 95,000)

Role: Principal Investigator

Duration: 2016-2019

Description: The outcome of the work will result in the development of cellular geoploymer masonry blocks for use in construction using fly ash, with minimal processing energy (hence a low carbon footprint). The use of fly ash as the only precursor raw material for producing the new material suitable for use in construction offers the potential for environmental beneficiation through the large-scale effective use of waste material from industrial and post-consumer utilization, disposal of which has become a challenge. Additionally, the inherent benefits of enhanced thermal comfort and internal environment through superior attenuation of noise make it suitable for use as a building material.

 

Project Title: Embedded Smart Sensor Design for Internal Stress and Damage Detection in Concrete

Agency: SERB, Department of Science and Technology

Amount: Rs. 3,672,000 ($ 53,5000)

Role: Principal Investigator

Duration: 2014-2018

Description: The central idea of this proposal is to pursue the conceptual development of an embedded sensor system, which allows for simultaneously monitoring the level of internal stress and the associated damage in concrete. It is proposed to integrate information from multiple embedded sensing elements. The methodology for inferring the level of internal stress from measured physical strains in the embedded sensing elements will be developed using the concepts of micromechanics. In addition, embedded Piezoelectric based PZT smart sensors will be used to monitor the development and progression of internal damage due to the internal stresses. The outcome of the proposed research will form the basis for designing a sensor system suitable for internal stress measurement and damage quantification in concrete structures.

 

Project Title: Center of Excellence in Sustainable Urban Development

Agency: Ministry of Human Resource Development

Amount: Rs. 40 million ($ 6 million)

Role: Center Coordinator and PI

Duration: 2014-2020

Description: Funding has been provided to establish a Center of national/international importance in the area of sustainable urban development. The Center aims to promote multidisciplinary research and training in new and emerging technologies in the areas of water, sustainable infrastructure, clean environment, smart materials and sanitation that promote sustainable development. We will also explore communication and sensor technologies for future cities and Sociology of Digital Societies.
