Development of a Method for Measuring the Layered Moisture State of Concrete and Various Bases

Abstract

To determine the resistance of concrete, an automatic AC bridge with a digital counter P5058 with a measurement limit of 10 Ohm to 3.9 MΩ was used. The study of mass transfer processes under the conditions of layer-by-layer concreting using dry mixes is of great importance for finding the optimal options for the method being developed and for choosing approaches to control the process of structure formation of such a complex system as mixed concrete - dry concrete mix - soil base. Taking into account the difficulty of determining moisture content by direct sampling of shots, when a special stop of the hydration process is required, the work focused on the development of remote methods for measuring moisture content.
