CONCRETE MIX DESIGN WITH FLY ASH FOR HIGH RISE BUILDING. CONCRETE MIX DESIGN

      Аннотация: The Modern high-rise concrete buildings are models of design skill in the use of materials. The trend toward buildings other than rectilinear in shape is producing some unusual structural members. All of these factors spell placing problems unless a mix design is formulated that produces concrete of considerable flow ability and high quality. Fly ash, a waste generated by thermal power plants is as such a big environmental concern. The report is carried out to study the utilization of fly ash in cement concrete as a partial replacement of cement as well as an additive so as to provide an environmentally consistent way of its disposal and reuse and analysis of Mix Design. The use of fly ash in concrete has many benefits and improves concrete performance in both the fresh and hardened state. Fly ash use in concrete improves the workability of plastic concrete, and the strength and durability of hardened concrete. Fly ash use is also cost effective. When fly ash is added to concrete, the amount of Portland cement may be reduced.
