The majority of fly ash produced in India is low calcium fly ash The use of fly ash as admixture in cement mortarconcrete not only extends technical advantages to the properties of cement mortarconcrete but also contributes to the environmental pollution control Key words Quarry dust fly ash compressive strength transverse strength
Therefore the concurrent use of quarry dust and fly ash in concrete will lead to the benefits of using such materials being added and some of the undesirable effects being negated The increase in workability by the addition of quarry dust is reduced by the addition of fly ash The concurrent use of the two byproducts will lead to a range of
It was observed that the decrease in early strength by the addition of fly ash is ameliorated by the addition of quarry dust Therefore the results of this study provide a strong recommendation for the combined use of quarry rock dust and fly ash in mortarconcrete manufacturing Quarry dust qualifies itself as suitable substitute for river sand
However the use of fly ash leads to a reduction in early strength of concrete The use of quarry dust in concrete is desirable because of benefits such as useful disposal of a byproduct reduction of river sand consumption and increased strength However the use of quarry dust leads to a reduction in the workability of concrete
Jan 01 2020 · Three various batches of the foamed concrete were considered in this study as follows Batch I the conventional mix including fine aggregate cement foaming agent and water Batch II which used the same ingredients except for the partial substitution of fly ash for cement and Batch III which used the combination of cement and fly ash as the binder content and river sand has been partially replaced by Quarry dust
The compressive strength of concrete with 20fly ash 50quarry dust alone is about 15673 of conventional concrete The compressive strength of concrete with 30fly ash 50quarry dust aloneis about 14673 of conventional concrete The concrete with fly ash quarry dust is more economical than ordinary conventional concrete
It was observed that the decrease in early strength by the addition of fly ash is ameliorated by the addition of quarry dust Therefore the results of this study provide a strong recommendation for the combined use of quarry rock dust and fly ash in mortarconcrete manufacturing Quarry dust qualifies itself as suitable substitute for river sand
Jan 01 2020 · The experimental test result of 30 of fly ash with 30 of quarry dust shows that the higher split tensile strength is 175 MPa at 28 days with the wb ratio of 04 Further the addition content of fly ash in Portland cement there is a decreasing trend was noted in the case of F15F16 mixes
