Comparative Study on Geopolymer Coated Recycled Aggregate Concrete
Department of Civil Engineering, Haldia Institute of Technology, West Bengal, India E-mail:soumi7492@gmail.com, rajadas1707@gmail.com, atrayee00@gmail.com, sngcehit@gmail.com At present India is witness to rapid development in all sectors leading to an increased need of new infrastructures at low cost and less time. Creation of new infrastructure deals with either demolition and repair of existing buildings or construction of new facilities altogether. However, demolition of buildings generates huge construction waste and new construction demand fresh conventional construction materials, production of which are associated with depletion of natural resources and emission of CO2 and greenhouse gases. Since conventional and traditional construction materials like cement, coarse aggregate, fine aggregate, etc., are all obtained from natural resources by means of complex extraction procedures, a shortage in future availability is certain, Recycling and reusing of this concrete waste as alternate construction material not only will reduce the demand for natural resources but also minimize the area required for landfills and illegal dumping. But often the recycled aggregates obtained by crushing into desirable size is found to be contaminated with old mortar leading to disadvantages like relatively more water absorption, poor surface texture and formation of weak interface between aggregates compared to natural aggregate. To account for these disadvantages some recent studies have suggested the use of fly ash in the mix design. Hence, considering the variety of available of fly ash in India, a detailed comparative study is undertaken to understand the influence of characteristic properties of different fly ash on the performance of the various resulting compositions of recycled aggregates.
