“…Their results showed a higher compressive and splitting tensile strengths of control than the 5, 7.5,10, 12.5 and 15% PC replacement with RHA. Srinath et al (2021) used a ternary mix containing PC, high silica (86.94%) content, grey, irregular and non-crystalline RHA with particle size >45 microns and hydrated lime in examining the mechanical properties of an eco-friendly normal strength concrete. The results revealed that PC replacement with 10% RHAþ10% hydrated lime gave the best mechanical properties values among other mixes.…”
