Concrete is the most versatile construction material mainly because of moulding ability & high compressive strength. Concrete requires large amounts of cement. The cement industry consumes lots of natural resources & moreover the production of cement causes air pollution. Flyash is a by-product from thermal power stations which is generated in massive quantities & its disposal is a great issue. If this is used in concrete as a replacement of cement, the issue of its disposal can be addressed to a certain extent. The pozzolanic properties of flyash enhance the properties of concrete in it’s fresh as well as hardened state. High volume flyash concrete (HVFAC) is the concrete with high volumes of flyash (50% or more) of cement content. In the present paper, an attempt has been made to highlight the fresh properties of concrete such as workability and compressive strength by replacing cement at replacement levels of 40%, 60% & 80% by weight with flyash and a comparison is made with the available literature
