Abstract
A method of measuring the strength of concrete for the slip form process, to determine upward movement of a slide form so that the concrete poured in the slide form will be released therefrom after setting to a degree of strength capable of maintaining the shape of a structure to be constructed. According to the method, an arithmetic unit calculates the temperature integral of the concrete poured in the slide form on the basis of measured data given thereto by a temperature sensor having a plurality of measuring elements and inserted into the concrete and by an altimeter that measures the position of the slide form. The strength of the concrete is determined from the known relation between the temperature integral and the strength of the concrete.
