Jun 30, 2021  Normal concrete with 0% Rice Husk Ash showed concrete compressive strength was 2,554 psi after 7 days curing, 2,750 psi after 21 days curing, and 2,910 psi after 28 days of curing. RHA reduces the strength due to its porous nature which creates porous concrete and leads to less packing density, which in turn results in less strength.

When this husk is completely burnt, about 25% of rice husk ash (RHA) is generated [1]. It was proven that the RHA contains about 85–95% of amorphous silica [2, 3, 4]. However, this silica is not easily biodegradable and mostly used for landfill. It was also well-documented that RHA shows both filler and pozzolanic effect in mortar and concrete.
