Modelling of Strength Parameters of HVFAC Roads

The Concrete industry across the world is facing a challenge due to the depletion of the natural minerals used in making OPC, and it has become necessary to search for other pozzolanic materials. In research, it is found that various industrial waste materials like Fly ash, Ground Granulated Blast Furnace Slag (GGBFS), Copper Slag have pozzolanic and cementitious properties. Fly Ash is one of the best materials to use in cement concrete works. Its usage has many advantages like, Concrete of better rheology, Enhanced strength and durability, Preservation of limestone reserves, and minimizing greenhouse gas emissions. High-Volume Fly Ash Concrete (HVFAC), due to above many advantages, came into existence, in which the use of fly ash has crossed more than 50% replacement of OPC (i.e., Cement: Fly ash is 50:50). Strength parameters (Compressive strength, Tensile strength, and Flexural strength) of the HVFAC play a very important role during the design, construction of the concrete members, mainly the rigid pavements. The aim of this project is to formulate Model equations for the strength parameters of the HVFAC for various water/binder ratios at different concrete ages. These models are helpful in finding out the unknown parameter by just substituting the known values in the model equations.
