Description

This is a recorded webinar from September 13, 2016.

The strength monitoring of concrete in the job site is a critical step in the optimization of important operations such as formwork removal, opening traffic on the concrete pavement, post-tensioning, concrete curing, and application of load of concrete elements during construction. In most projects, field-cured cylindrical specimens are cast on the job site and are tested in laboratory at various times to monitor strength. Among various NDT methods for in situ measurement of strength, concrete maturity method has been adopted by many standards and building codes worldwide. As per specifications in the ASTM C1074 standard, this method requires continuous monitoring of concrete temperature after pouring, and subsequently strength estimation using a pre-developed calibration curve. A successful implementation of this test method in construction projects can significantly improve the speed and efficiency in order to avoid delays in project completion time.

In this webinar, the basic concept of concrete maturity will be presented. Various methods of testing concrete maturity including the Nurse-Saul, Arrhenius, and Weighted Maturity will be reviewed. Different testing apparatus, sensors, and tools used for concrete maturity testing will be demonstrated. Application challenges, limitations, and important practical considerations will be discussed. Various examples, applications, and case studies will be presented.
