Measurement of Volume Changes of Cement Concrete in Large-Dimensional Samples

Abstract:

The subject of the paper is research on the development of volume changes (especially shrinkage) on cement concrete. This is a measurement of shrinkage on large samples using string strain gauges both internal and external. Parallel to this measurement, according to the real concreting conditions, the volume changes will be measured by means of shrinkage drains in the test laboratory. This will make it possible to compare a comparatively progressive method of measuring volume changes with the real behavior of the same concrete in the structure. The measurement of volume changes by the shrinkage drains is a comparatively rare test allowing continuous volume changes to be measured from the beginning of the setting of the concrete. It is possible to capture the entire process of hydration of concrete. The paper will describe the technology of measurement and comparison of both methods on ordinary concrete.
