  • FLY ASH CONCRETE WHAT ARE THE REASONS FOR

    Fly ash in concrete contributes to a stronger, more durable, and more chemical resistant concrete mix The main benefit of fly ash for concrete is that it not only reduces the amount of nondurable calcium hydroxide (lime), but in the process converts it into calcium silicate hydrate (CSH), which is the strongest and most durable portion of the Partial size of the fly ash is in the range of 1100 microns (01mm) and the average size is about 20 microns which is similar to the Portland cement average particle size Fly ash can be used as prime material in many cementbased products Pouring concrete, concrete blocks and brick construction can be identified as common uses of it There Fly Ash Concrete [why should it be use] Structural GuideDust and Cement by Fly ash The innovative use of Quarry Dust in concrete formulations as a fine aggregate replacement in the range of 0%, 15%, 30% 45% by weight for M40 grade cement (PPC) Fly ash is also used as partial replacement of cement in the same proportionExperimental Study on Use of Quarry Dust and Fly Ash with
