TESTING HARDENED CONCRETE USING THE MATURITY CONCEPT

Abstract

The paper provides an overview of different methods that can be used for concrete maturity determination, outlining Romanian Concrete Code Specification (NE 012-99) in relation to using an effective and rational method in evaluating in-situ concrete strength at different ages.

Keywords
