Abstract

Geopolymer concrete is one of the green concrete. It becomes a solution on social environmental problems, such as disposal of fly ash produced by thermal power plants and the air pollution due to production of cement. Geopolymer concrete is very advantageous due to its durability, economy and environmental credit point of view. The Geopolymer requires the temperature curing for obtaining the sufficient strength. Practically it is impossible to produce the temperature curing to structure at site. Due to that this concrete is only useful for construction of precast members in industry. If geopolymer concrete attains the required strength at room temperature this will be the boon to society for saving the environment. Some effort is made in this direction for achieving the sufficient strength of Geopolymer cure at room temperature. The various percentages of Lime and OPC were added in fly ash for obtaining the strength at room temperature. The effect of lime and OPC on initial setting time and compressive strength were studied. From this experimental work it is observed that increase in the percentage of lime and OPC the initial setting time reduces as the compressive strength increases. In case of strength the Geopolymer mix incorporated with OPC gives the better results of strength as compared to the mix with lime.

Abstract

Considering the recent growth in the field of infrastructure development in India, many towns are getting upgraded into smarter cities. The challenge before the planer to set a well planed city is to overcome the problem related to parking that arises due to increasing number of vehicular traffic. In many cities it has been observed that the residential parking space is provided in the building itself by utilizing open ground storey. Past earthquakes have demonstrated the vulnerability of such kind of structures. Infill walls act as a lateral force resisting element for high rise structures. But less amount of research is dedicated to understand the behaviour of infill wall as a retrofitting method. Hence, the objective of this paper is to assess the potential of global retrofitting technique i.e. incorporation of infill walls in the open ground storey. For this purpose three dimensional models are adopted to understand the effect of infill wall. Comparative results are presented in graphical form to justify the chosen global retrofitting technique.
