SYSTEM FOR MONITORING MASS CHANGE CAUSED BY ATMOSPHERIC MOISTURE USING WEIGHTED WITNESS AND ISOLATED REFERENCE CONCRETE SAMPLES.

Abstract

The invention relates to a system that enables monitoring the mass change of concrete over time in reinforced concrete buildings, bridges, viaducts, tunnels, retaining walls and similar concrete structures due to the effect of atmospheric moisture, and includes at least one sample of concrete representing the building concrete (10), a balance / weighing unit (11) that measures the weight of the sample (10), a container (1) that holds the sample (10), a data recording and processing unit (15) that records the measurement data, a reference sample (13) isolated from atmospheric moisture and an isolated sample container (12) and a comparison unit (17) that compares the obtained weight change data with the reference sample (13), allowing the mass change of concrete due to atmospheric moisture to be monitored gravimetrically and the moisture behavior of the concrete to be evaluated.
