  • Seminar report on flyash concrete SlideShare

    1/24/2016· The fly ash concrete is more workable and less water is needed for the same slump. Although increased fineness usually increases the water demand, the spherical particle shape of the fly ash lowers particle friction and offsets such effects. The use of fly ash as a partial replacement for Portland cement will usually reduce water demand.

    A.: Jerzy Zemajtis of Construction Technology Laboratories says an excellent starting point on this topic is Fly Ash in Concrete, by V.M. Malhotra and A.A. Ramezanianpour, published by the Canadian Centre for Mineral and Energy Technology (CANMET) in 1994. For abrasion resistance the authors refer to a study by Carasquillo (1987) where a comparison

  • ACI PRC-232.2-18: Report on the Use of Fly Ash in Concrete

    Fly ash is used in concrete and other portland cement-based systems primarily because of its pozzolanic and cementitious properties. These properties contribute to strength gain and are known to improve the performance of fresh and hardened concrete, mortar, and grout. The use of fly ash typically results in more economical concrete construction.
