Application of Maturity Meter to Estimate Location of Sensors for Plate Elements

Abstract

The quality assurance of concrete structures mainly depends on the measure of the in-place strength of concrete. The in-place strength of concrete plays an important role in planning the activities on-site such as opening of structure of occupancy, opening of roads to traffic, construction claims, etc. The strength of concrete is a measure of temperature and time. This research work scrutinizes the application of “Maturity Method” in finding the location for placement of sensors in plate elements, specifically a squared manhole cover. A trial program is proposed to detect the distress locations in a manhole cover using maturity meter. For this study, three non-sacrificial sensors were placed in a manhole cover and hydration extent was examined. Further, the results were interpreted in excel on the basis of the correlation between the three sensors placed in the manhole cover kept at room temperature where concrete hydration was permitted.
