A Detour into Fly Ash. Fly ash is the main component of Ashcrete. It is used to replace cement in the concrete mixture due to its natural pozzolanic properties. This means that, like volcanic ash, fly ash reacts with calcium hydroxide in the presence of water to produce a strong, sturdy material that is stronger than regular cement.
The split tensile strength of fly ash blended concrete up to 40% replacement levels after 7,14, 28 days curing are shown in Table 8. It can be observed from the table that up to 30% replacement of fly ash the split tensile strength has not been affected. Beyond 30% replacement level, a slight decrease in split tensile strength is observed.
