NEW TECHNOLOGY AND MATERIALS FOR CONSTRUCTIONS OF INSULATED MASONRY
Abstract
The paper refers to an experimental program aimed at evaluating the characteristics of masonry, with the objective of developing an innovative system for masonry, destined to be used for facades and envelopes. The purpose was to develop new masonry elements with good performance at thermal transmittance and good behavior at noise, fire and durability. Technical and economic feasibility of the masonry prototype systems was validated by experimental tests, according to European standards. The strategy for the development of the products is to assure walls requirements and design parameters for masonry elements, according to the constructions traditions and environmental conditions. The masonry elements were designed in accordance with the requests of the seismic code-Eurocode 8 and the National Annex P100-1:2013 for structural role, and also in concordance with the thermal characteristics for increasing safety and quality of life. The masonry elements are made of three layers: two exterior non-structural coating made out of rock wool and ceramic protection and a central layer which is considered to have a structural role. The design of the central layer was made according to the requirements for seismic zones in terms of geometry and material characteristics. The exterior layers are not taken into calculation for the design phase; all strength is determined by tests, in relationship with the central layer. The research program is developed with the aim of attaining the main characteristics of masonry which are necessary for analysis and engineering practice in seismic areas. The new technology work was analyzed and evaluated by using the prototype masonry elements. The result of the program aims to integrate new materials, techniques and methodologies in the construction practice in order to increase the quality of life in seismic areas.
