Concrete cures slowly; the design strength is usually reached 28 days after initial setting.
Concrete cures and its strength increases over time, and tests are performed at 14 days, 28 days and 56 days.
Parts of these support materials used to form the shape of the concrete must then be left in place for 14 to 28 days, a period during which the concrete "cures" and gains a much greater capacity to hold weight.
PF-reinforced concrete cured via water immersion exhibited the best concrete strength.
However, concrete curing performance may decrease due to physical and chemical factors depending on the exposed environment.
The GPR identifies the subsurface condition, which permits the user to determine the moisture availability for potential concrete curing.
The tests were performed at different stages of concrete curing using both the 1500 MHz and the 2600 MHz antennas.
MSF concrete cured by steel and polypropylene materials shows much higher pore volume amount than plain and FA concretes for the pore size between 0.1 and 1.0 μm.
The porosity of concrete cured with continuous moistening was lower compared to those under hot weathering.
Evolution of compressive strength of concrete cured at 60 °C was monitored.
