  • Page 6: Concrete Strength Calculation

    Carbonization depth: concrete carbonization depth is a kind of chemical corrosion of concrete, and the process reducing concrete alkalinity is called concrete carbonization. Carbonization depth value can be obtained according to the relevant methods of Regulations. When input carbonization depth, only have to input a number between 0.0mm and 6.0mm and then the apparatus can, according to the input carbonization depth value, calculate the concrete compressive strength value.

  • Page 8: Calculation Of Concrete Strength Under Customized Measuring Mode

    If testing the concrete casting side is in horizontal direction, then angular correction and casting surface correction are not needed. Before the test, test direction and concrete casting surface are set, so the apparatus will correct the average rebound value automatically.
