This paper analyses the structure made from fair faced concrete compared to a conventional concrete sandwich structure with a surface finish in terms of bound CO2 emissions. This article also takes into account the length of service life of the individual constructions. For each of these structures, an analysis for high-performance concrete (HPC) and conventional iron-reinforced concrete (sometime called normal strength concrete NSC) is provided. Due to the current tendency of construction from colored fair-face concrete, tentative calculation of color pigments’ influence on the amount of bound CO2 emissions production is also performed. From the results we can concluded, that The structure made of HPC shows a higher production of bound CO2 emissions, but its declared durability is higher compared to the NSC construction. The use of colored inorganic pigments resulted in an increase in GWP (Global Warming Potential), and the construction of colored exposed concrete shows nearly three times the production of bound CO2 emissions.

Obsahem této práce je analýza a interpretace díla architekta Jindřicha Mergance jako zástupce absolventů českých architektonických škol působících na Slovensku. Časové rozmezí je vymezeno životem architekta mezi lety 1889 až 1974. V práci jsou reflektovány jak osobní, tak politicko-společenské události, které společně s dobovou uměleckou diskuzí tvoří rámec výzkumu. Cílem je představit tvorbu Jindřicha Mergance v celé jeho šíři a pokusit se v ní najít autenticitu architektova vyjadřování.

Socialistická architektura tvoří neoddělitelnou součást našich měst. Stejně tak jako architektura jakéhokoliv jiného období vypráví důležitý příběh minulosti. Přesto, nebo právě proto si ji většina lidí spojuje především s režimem, který nás na čtyřicet let uzavřel před svobodným světem. Tyto často negativní konotace jsou o to silnější vůči bývalým budovám Komunistické strany Československa, ke kterým si jen obtížně hledáme pozitivní či alespoň neutrální vztah.

This paper summarizes the results and evaluation of the push-out shear tests of the timber-precast concrete composite connection designed for lightweight pedestrian bridges. The timber-concrete composite bridge structure consists of glulam beams connected with precast segments made of UltraHigh Performance Fiber Reinforced Concrete (UHPFRC). A shear connection is carried out by notches made of steel plate embedded in the timber beams supplemented with welded shear dowels (headed studs) situated in the concrete part of cross-section. The precast slab is provided with slots for the shear dowels. After placing of the deck segments on the timber beams, the slots are poured with UHPFRC. The short-term push-out shear tests are carried out. The test specimens are composed of two identical precast UHPFRC slabs and timber beam placed in the middle between them. Some parameters of the shear connection are varied and their influence on the mechanical behaviour of the connection is discussed. The executed experiments are supplemented with numerical simulations. The results obtained from the experiments and numerical analysis are compared with analytical calculation.

Influence of different type of mould-release agent on surface properties of coloured concrete is presented in this paper. The quality of exposed concrete areas is directly affected by several factors. In addition to the most important factor, which is the influence of the outdoor environment, has the inconsiderable influence on surface properties of concrete manufacturing technology and the used material. This article is focus on roughness and colour intensity of concrete elements. Concrete samples were created in two color variations: yellow and red. Colour was obtained by measuring RGB number (Red-Green-Blue value) on several points on concrete surface. Two kind of mould–releasing agent on different chemical base were tested, (mineral oil base and silicon base). From the results, follows that the different kind of separators has impact on the colour of concrete. Measured data also show that there are differences in roughness and quality of concrete surface depending on used mould-release agents.

In this position paper, we present the results of ongoing theoretical investigation in the phenomenon of “interactive architecture.” Interaction in architecture deals with the meaningful exchange of information and physical acts between building and person. This goes beyond responsive systems like automated doors, shading systems, and so on. Most examples of interactive architecture are technological explorations that probe possibilities and potential of interaction. In this paper we claim that this is not enough. The notion of interactive architecture is explored through social aspects, user experience, situatedness, and agent-based theory. From this we argue that interactive buildings need comprehensive and consistent styles of interaction rather than series of isolated and unrelated interaction events. Different people in various contexts require different sets of behavior from an interactive building. These sets are conceptualized as “interaction narratives,” following the work of Maria Lehman. We argue that such narratives can provide a better fit of the interactive building with the user, and lead to more profound understanding of such systems.

This paper deals with the material properties of Ultra High Performance Fiber Reinforced Concrete (UHPFRC or UHPC) and especially focuses on bending tests executed for the development of bridge deck segments for an innovative timber-concrete composite bridge system. In the first step, the precast bridge deck segment is designed as a thin slab made of UHPC of a constant thickness, without any ribs and without any reinforcement. Only steel fibres are used as a scattered reinforcement. The bending tests for determining flexural strength of UHPC were executed on the slab strips under similar boundary conditions as by the bridge deck segments. The slab strips of various thickness of 40, 50, 60, 70 and 80 mm were tested in 4-point bending tests with span 1900 mm and in 3-point bending tests with span 600 mm. Half of the test specimens were tested in casting position, other half were tested upside down. The obtained values of the flexural strength were compared with values from reference bending tests of the beams 150 x 150 x 700 mm, 100 x 100 x 400 mm and 40 x 40 x 160 mm. Different size of the tested specimen is discussed. An influence of the positioning of the slab with respect to the direction of casting and the influence of the deck thickness on the flexural strength is evaluated
