G11: Evaluation and conservation of cultural heritage
Main field of activity: Development and implementation of the most advanced procedures for monitoring - investigation - diagnosis - treatment on different elements, categories of cultural heritage and different materials (stone, pigments, paper, parchment, wood, etc.). Mission: - Research activities in the laboratory and in the conservation sites as a result of the new requirements coming from the restorers and the specialists dealing with the practical conservation; - Use of advanced investigative techniques applied to establish the stage and degree of degradation of works of art, and recommendations regarding restoration and conservation operations; - Measurements on: the quality of the surfaces of the investigated parts, the study of the surfaces of very fragile monuments in a stage of accelerated degradation and the concentration of pollutants on the surfaces. Evolution of research directions: development of diagnostic and treatment technologies for the conservation and revitalization of the archaeological components of the cultural heritage: (i) Development of new micro- and nano-materials, new methods and technologies; development of new investigation techniques; (ii) Selection and characterization of historical materials; (iii) Evaluation of in situ materials and sampling of samples taken; (iv) Development of cleaning treatments for selected surfaces; (v) Polymer gel systems applied in conservation / restoration; (vi) Anti-slip and antimicrobial mats; (vii) Polymeric waste recovery compositions with improved properties.

Portable hardness tester Dyna Pull Off Tester – Dyna ESTRICH, PROCEQ
The Dyna pull off tester is used: to determine the surface strength of concrete and other materials testing it directly on the component allowing the use of any measuring point. Additionally for the measuring of the adhesive strength of applied coatings such as plastic coatings, concrete coats, and mortars and plasters. Measures the adhesive strength of applied coatings e.g. plastic or concrete coatings, mortars, plasters, bituminous coats. Determining the surface strength of concrete and other materials. The pull off tester is ideal for the evaluation of tensile strength in concrete renovation.
