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 the monitoring of the mass change of concrete over time due to the effect of atmospheric moisture in concrete structures such as reinforced concrete buildings, bridges, viaducts, tunnels, retaining walls and similar concrete structures, 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 of the concrete (10), a container (1) that holds the sample of the concrete (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 of the concrete (13), so that the mass change of concrete due to atmospheric moisture can be monitored gravimetrically and the moisture behavior of the concrete can be evaluated.
