ARHITECTURĂ ACCELERATION PROCESS OF CONCRETE’S DISSOLVING – LEVIGATION CORROSION BY DIANA PLIAN * and LIVIA-INGRID DIACONU “Gheorghe Asachi” Technical University of Iaşi Faculty of Civil Engineering and Building Services Received: February 24, 2015 Accepted for publication: March 12, 2015 Abstract. This paper presents a method for accelerate the dissolving- levigation corrosion of the concrete. Test steps and the device used for this purpose are described. The presented method simulates the behavior of the concrete in exploitation subjected to of this type of corrosion to assess the behavior in time of the concrete. Key words: concrete; corrosion; dissolving-levigation. 1. Introduction The corrosion represents the spontaneous, partial or entire destroy or decay of a material during its utilisation. The corrosion represents a natural phenomenon that can not be stoped but only retarding. There exists only a few materials that don’t suffer this phenomenon. The corrosion phenomenon is generated by the natural interactions between the environmental factors and a material. The interactions multitude between the environment (water and atmosphere) and materials can be classified in physical, chemical and microbiological interactions. * Corresponding author: e-mail: plian.diana@yahoo.com
