Overview

Randomized trial investigates fly ash inclusion and thermal curing to enhance reactive powder concrete properties, suggesting sustainable practices.

Key Points

  • This research aims to assess how fly ash incorporation and thermal curing influence the properties of reactive powder concrete (RPC).
  • Prepared four mixes of RPC: a reference and three with 10%, 20%, and 30% fly ash replacement (RF10, RF20, and RF30).
  • Applied thermal curing at 70°C for 5 hours daily over 3 days, followed by water curing until testing.
  • Tested specimens for mechanical properties at ages 7, 28, and 56 days.
  • RF20 mix exhibited the highest compressive strength improvements of 3.39%, 4.47%, and 4.86% at 7, 28, and 56 days, respectively.
  • Flexural strength and splitting tensile strength increased by 2.39% and 1.69% at 28 days, respectively, for RF20.
  • RF20 mixture demonstrated highest dry density (2683 kg/m3), lowest water absorption (0.114%), and lowest porosity (1.75%).
