    Enhancing the Freeze Thaw Resistance of Pozzolanic Lime Mortars by Optimising the Dewatering Process
    (Springer, 2024) Su-Cadirci, Tugce Busra; Ince, Ceren; Calabria-Holley, Juliana; Ball, Richard James
    Freeze-thaw weathering is commonly attributed to the premature degradation of lime mortars. This study is unique as it explores how the effect of incorporating pozzolanic brick dust, combined with the dewatering mechanism, can influence the resistance to freeze-thaw cycling. The combination of brick dust and hydrated lime constitutes a pozzolanic lime mortar with hydraulic character. Importantly, the addition of brick dust was shown to play a crucial role by modifying the pore structure of the mortar matrix, which affected the water transport kinetics, and durability. This rigorous investigation evaluates the freeze and thaw resistance of hardened young (7-day) and old (180-day) mortars in both dewatered and non-dewatered conditions. Quantitative analysis of the microstructure highlights the role of brick dust and dewatering in densifying the matrix, refining the pore structure, and enhancing the freeze and thaw resistance. The benefits of dewatered brick dust mortars were demonstrated as young-age dewatered mortars showed similar resistance to freeze and thaw compared to the older-age non-dewatered mortars. This was attributed to the reduction of the water/binder ratio due to dewatering. It has been successfully demonstrated that freshly mixed mortars can be enhanced on-site through the addition of brick dust and coupling with a substrate that promotes dewatering. Using this approach to produce mortars with greater freeze thaw resistance will improve longevity and reduce failure rates. Impact will be realised in mortars for both new build and conservation applications.

    Educating Masses: The Committee of Union and Progress Clubs and Schools in the Late Ottoman Empire
    (Routledge Journals, Taylor & Francis Ltd, 2022) Tozoglu, Ahmet Erdem
    This article examines the social and architectural context of an extensive building campaign in Turkey in the early twentieth century. The Committee of Union and Progress (CUP), one of the Second Constitutional Period's prominent political and cultural actors (1908-18), commissioned club and school buildings for social outreach operations. Influenced by their European counterparts, the Committee's protagonists believed that a social revolution could be accomplished by employing the education of the masses. Moreover, education was also essential to create a national identity for an Empire in a struggle. In this context, many clubs (for adults) and schools (for the youngsters) mushroomed in many cities simultaneously. Accordingly, the architecture of new club and school buildings reflected societal concerns and provided remarkable examples of their kinds. The education of the masses and the use of social propaganda by state agents in Republican Turkey have been scrutinized so far. Still the origins of the social engineering projects should be examined to contextualize Republican period developments. Thus, this article examines the building and impact of the clubs and schools of the CUP in the provinces and constitutes a contextual frame for their formative role in Turkish modernization.

    Evolution of Production Spaces: A Historical Review for Projecting Smart Factories
    (Konya Technical Univ, Fac Architecture & design, 2023) Basegmez, Merve Pekdemir; Asiliskender, Burak
    Factories are transforming not only mechanically and technologically but also architecturally due to emerging developments in the industry and fabrication: This new process, called the Second Machine Age or Industry 4.0, a new model is designed in production by providing the human-machine partnership over a virtual network. It is aimed that the machines used in production and the people participating in different stages of production can work in different spaces. In time, jobs that require human power will be replaced by robots, and a new order is being considered where there will be no people in production spaces, and they can work in the virtual environment. Production for human beings is mostly from material production to digital production; labour will turn into digital labour. For this reason, it is thought that production spaces will turn into smart factories with only machines and production robots and no workers. And now the question is: what is a smart factory?The revolutions in the industry history started with the invention of the steam engine; then, new technological revolutions were experienced with the use of electricity in production, the development of automation systems and internetbased systems. While technology and production tools are constantly changing, these developments also affect production spaces. Factories are also transforming to keep up with these rapid and continuous physical and fictional innovations. This study focuses on the architectural evolution of factories by following the technological revolutions of the industry. It examines the main criteria in the process of change and transformation of factories and spatial reflections of the revolutions. It establishes a relationship between production technology and the needs of the production spaces and seeks references from past samples. The study aims to review the historical background for generating a projection to new production spaces and to be a new discussion for future factories.
