Abstract: This paper elaborates on the evolution of architectural form, building materials and structural solutions in the building planning and design process (BPDP), which is heavily conditioned by science and the level of technological advances, as well as by the roles of the key players (designers and engineers) in that process. The goal of conducted analysis is to, based on the values of traditional and conventional approach to building planning and design, come up with such system of designed/built environment, which will not jeopardize the complex system of a given/natural environment. By comparing the traditional (comprehensive, masterful work) and conventional (fragmented, specialized) approach to BPDP, it could be concluded that what is good in the old one is its holistic, integrated nature; while the new opportunities provided by a joined development of science and technology are benefits of the current moment, i.e. conventional BPDP

Abstract: Severe damages such as expansion, cracking, spalling, have been observed in a public facility (communal library) recently built in the northeastern region of Algeria. Microstructural examination of the concrete samples extracted from different structural elements revealed an abundant presence of thaumasite in association with ettringite and/or gypsum. The thaumasite was found within cavities at the interfaces aggregates/cement as well as in the high dolomitic cement matrix. The deterioration of the concrete studied was attributed to the thaumasite sulphate attack (TSA) supporteess by the alkali dolomite reaction (ADR). With regard to the semi-arid nature of Algerian climate, it appears that the condition of low temperature (less than 5 ° C) required for the formation of thaumasite reported in the literature seems to be not necessarily true
