Mostly-printed structures are subjected to compression that is oriented perpendicular to the layer laying direction. When applying load in this way, the printed structure exhibits characteristics similar to masonry structures. However, as the technology and application of 3D printing develop, the structures also become more complicated and subjected not only to direct compression but other stresses as well. In this paper, long-term properties together with compressive strength were determined for 3D-printed specimens with load applied in the same direction as the layers are laid. The long-term and mechanical properties were compared with cast same-composition specimens. Results show that for the printed specimens, the compressive strength was more than two times lower than cast specimens, while the creep properties were slightly lower for the printed specimens.","PeriodicalId":298795,"journal":{"name":"10th MATBUD’2023 Scientific-Technical Conference","volume":"536 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116494749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research focused on facades with thin-layer acrylic plaster and sheet-metal components made of aluminium, copper and hot-dipped galvanized sheet metal. Two different test methods and test sample geometries were used to determine the most critical aspects for the studied application sectors. Surprisingly high tensile properties as well as shear stresses in the bonded joints were recorded for all the selected combinations. The presented results confirmed the assumed benefits for the construction industry and the future practical use of this technology in construction, although the durability of a bonded joint will always depend mainly on the quality of the bonded substrate.","PeriodicalId":298795,"journal":{"name":"10th MATBUD’2023 Scientific-Technical Conference","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132201665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In subsequent tests, these materials were gradually replaced with up to 10% CEM I cement. Their effects on consistency and compressive and flexural tensile strengths after 28 days of maturation were investigated. The tests were carried out on blocks measuring 40 mm × 40 mm × 160 mm according to the standard. In the range of tests analysed, the results obtained make it feasible to consider the possibility of partially replacing cement with silica fly ash and ground granulated blast furnace slag in cement mortars.","PeriodicalId":298795,"journal":{"name":"10th MATBUD’2023 Scientific-Technical Conference","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132430133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two types of standard C30/37: XC1 concrete were used in this study, one with the aggregate size limit 19 mm and the other with the aggregate size of max. 4 mm. The basalt fibers used are two different types: Reforcetech minibar is a stiff basalt fiber, and its diameter is 0.72 mm and length 50 mm; Basaltex BCS17-25.4-KV1 is 30 mm in length with a flat cross-section of 0.017 × 4 mm. The test method measures the flexural efficiency of the strength parameters extracted from fiber reinforced concrete. The conclusion of this study is that the scale, quantity and type of basalt fibers have an impact on how the concrete acts under load. All types of fiber show promising results.","PeriodicalId":298795,"journal":{"name":"10th MATBUD’2023 Scientific-Technical Conference","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115692624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, residential buildings consume about 40% of the energy that we are able to produce. Construction product manufacturers implement innovative solutions that give us a chance to achieve more widespread construction of zero-emission and zero-energy buildings. However, they face legal barriers related to the lack of standardization procedures enabling the rapid placing of innovative construction products on the market to be achieved. The MEZeroE project (“Measuring Envelope products and systems contributing to next generation of healthy nearly Zero Energy Buildings”), funded by European Union Horizon 2020, aims to create a platform combining science and business to facilitate the development of nearly zero-energy buildings. The aim of this paper is to present the European procedure for placing innovative construction products on the market under the MEZeroE project.","PeriodicalId":298795,"journal":{"name":"10th MATBUD’2023 Scientific-Technical Conference","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132962670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The material’s resistance to the fungi is evaluated by exposing specimens to the fungus for 16 weeks, and then determining the mass loss and changes in mechanical properties. An important pre-testing step is cleaning the samples of mycelium. The study compares the effects of the manual cleaning method with a soft brush and with water under pressure. The aim of the study is to select a method that is non-destructive to the material. The results will be evaluated by mass loss, bending strength and modulus of elasticity.","PeriodicalId":298795,"journal":{"name":"10th MATBUD’2023 Scientific-Technical Conference","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115572631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using clay bricks causes erosion, lowers the water table, and harms the environment. This research examined various waste materials, including fly ash, quarry dust, marble dust, eggshell powder (ESP), and rice husk ash (RHA), in varying percentages to avoid using clay in manufacturing bricks. Compressive strength and water absorption tests were conducted, and the results were compared with the specifications for traditional clay bricks. It was observed that the compressive strength and water absorption values met the relevant standards needed for standard construction bricks. Furthermore, the cost of manufacturing bricks from waste materials was estimated, and the findings show that manufacturing bricks from waste materials cost less than conventional bricks. Finally, it was concluded that the brick industry could become more sustainable and economically feasible by using specific waste materials in manufacturing bricks","PeriodicalId":298795,"journal":{"name":"10th MATBUD’2023 Scientific-Technical Conference","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128032680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The question that was investigated was if superabsorbent polymers can act as an intermediate environment, intensifying the incorporation of TiO 2 particles on the surface of the tested material. Four variants of surface modification were designed: water dispersions of TiO 2 with non-saturated SAP, with SAP in a hydrogel form, and two reference series. Due to the use of SAP, the efficiency in air purification from NO x under different light conditions compared to the reference series increased significantly, exceeding a 75% increase under a UV-A light and a 600% increase under visible light.","PeriodicalId":298795,"journal":{"name":"10th MATBUD’2023 Scientific-Technical Conference","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130941347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
