Sustainability of concrete pavements considering traffic and de-icing agents
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)In concrete pavements, special conditions, that increase the likeliness of damaging reactions, as for example an alkali-silica reaction (ASR), prevail. Especially to the superposition of microstructural degradation caused ... -
Sustainable concrete production with recycled concrete wash water beneficiated with CO2
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)A significant amount of wastewater is generated through the cleaning of equipment utilized within the ready mixed concrete production cycle. The reuse of concrete wash water as mix water is limited by the negative material ... -
Technical effectiveness of cement-based mortar for high-reflective building envelope through building energy simulations: preliminary results
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)In areas with high levels of solar radiation, decreasing the amount of solar energy absorbed by the building envelope is useful to reduce the need of air conditioning and "heat island" effects. Most high-reflective products, ... -
Tensile behavior of newly developed undercut anchor in cracked and uncracked concrete
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The authors have been designing a post-installed anchor that fixes itself into concrete material by expanding the anchor tip in an upward direction, and conducted tensile loading tests to confirm its fundamental dynamic ... -
The role of conceptualization in the evaluation of sustainable concrete
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Improvement of the sustainability of concrete materials will be realized through the development of analytical tools that facilitate sustainable design and evaluation. However, these processes may be dependent on how ... -
The status of sustainable concrete codes in the United States
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)As the focus on embodied carbon within the built environment has grown in the U.S., local jurisdictional codes have increasingly proposed and implemented code language that requires the use of concrete mixtures that have ... -
Thin concrete overlays wit carbon reinforcement on deteriorated concrete pavements
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)In many countries, concrete pavements are normally built as Jointed Plain Concrete Pavements. Due to a lack of alternatives, repairing deteriorated concrete pavements usually requires the replacement of the complete pavement ... -
TRC sandwich solution for energy retrofitting
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Concerning energy improvement of existing façades, a favourable system involves prefabricated multilayer panels, made of internal insulation core and outer textile reinforced concrete layers. It is a convincing alternative ... -
Unique and innovative technology for sustainable and efficient structural concrete made of 100% recycled aggregate from CDW
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)For supporting an environmental and social approach to the construction industry, the authors are bringing a new unique technology for maintaining the production of sustainable and efficient structural concrete made of ... -
Use of recycled concrete fines in cement and as aggregate
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The research project focused on investigating and optimizing the processing and use of recycled crushed sand 0/4 from concrete demolition waste, as an alternative raw material in the cement and concrete industry. Crushed ... -
Using an analysis of concrete and cement EPD: verification, selection, assessment, benchmarking and target setting
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The carbon embodied in buildings is an important proportion of our emissions and needs to be radically reduced in order to support climate change mitigation. The highest proportion of embodied carbon is usually emitted ... -
Using an analysis of concrete and cement epd: verification, selection, assessment, benchmarking and target setting
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Carbonation of concretes is a natural physico-chemical process that can be described as a reaction between the carbon dioxide contained in the air and the cement matrix. Carbonation concerns all concretes types in contact ... -
Utilization of recycled and secondary materials in concrete production - LCA
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The paper describes an assessment of concrete in terms of environmental impacts in relation to the utilization of recycled materials. The article includes a short summary of the literature search on evaluation methods for ...
