Article Preview

The performance of materials made from Portland cement is usually evaluated by tensile strength under compression loads, elastic modulus and porosity. Modulus of elasticity is usually determined from compression tests, and the results show large dispersions. With the advances in data acquisition and signal processing, the infrared thermography and forced resonant frequency have been increasingly used in the study of materials. However, these studies are devoted almost entirely to metals. In this paper it is evaluates the use of the method of forced longitudinal resonance frequency and infrared thermography as a tool for characterization of the buildings cementitious materials. The results show that thermography and forced resonant frequency are Able to detect changes in concrete macrostructure as well as the nature of its constituents.
