Effects of dielectric heating of fresh concrete on its microstructure and strength in the hardened state

•Dielectric heating of fresh concrete with radio-waves is introduced.•A uniform, rapid and accurate, temperature-controlled heating was achieved.•High early-age compressive strength was measured.•Microstructural characterisation showed changes due to heat treatment. By means of radio-wave technology...
