Rate My Professor Vijaya Rangan

Professor Rangan's research specializations focus on concrete structures, high-performance concrete, and innovative sustainable materials, particularly low-calcium fly ash-based geopolymer concrete. His studies encompass mixture proportions, workability, compressive and tensile strength, fracture properties, elastic modulus, drying shrinkage, creep, permeability, acid and sulfate resistance, and structural performance in elements like beams, columns, slabs, walls, and panels. Key publications include 'Development and Properties of Low-Calcium Fly Ash-Based Geopolymer Concrete' (2005), 'Fly Ash-Based Geopolymer Concrete' (Research Report GC 2, 2008), 'Low-Calcium, Fly-Ash-Based Geopolymer Concrete' (2008), 'Shear Design of Reinforced Concrete Beams, Slabs and Walls' (1998), 'Modified Guidelines for Geopolymer Concrete Mix Design Using Indian Standard' (2012), 'Geopolymer Concrete Using Fly Ash' (2013), 'Early Age Properties of Low-Calcium Fly Ash Geopolymer Concrete Suitable for Ambient Curing' (2015), and 'An Experimental Study of the Long-Term Behaviour of Composite Steel-Concrete Beams' with partial shear connection. With over 10,000 citations, Rangan's work has significantly influenced the field by promoting geopolymer concrete as an environmentally friendly alternative to Portland cement-based concrete, utilizing industrial waste fly ash to reduce carbon emissions and costs.
