The building construction industry is in need of sustainable materials and solutions. A novel material, such as textile-reinforced concrete (TRC), could be used to meet this demand. Textile-reinforced a combination fine-grained multiaxial textile fabrics that has been fundamentally researched over the past decade. TRC-based research explored various facets composite its structural functionality, production, applicability, design. One key aspect still missing, however, comprehensive review...

Strategic reuse of demounted concrete elements in new buildings may be one the solutions that will support transition to circular construction. To ensure wider application reuse, RISE developed a methodology for assessment structural condition existing buildings, and selection suitable including guidelines their disassembly, storage, installation. However, main obstacles wide is uncertainty concerning remaining service-life evaluation quality over future building. This paper describes...

The problem of graffiti is not entirely restricted to urban areas, but also appears frequently in rural communities and along traffic infrastructure. Besides its aesthetic societal effects, cause considerable removal costs subsequent for repairing damages caused by improper removal. Over the last two decades, strategies have been developed combat built environment, including development protective measures form antigraffiti systems (AGSs). Antigraffiti promise be affordable easily applicable...

Abstract Cultural Heritage objects are in many cases invaluable and irrecoverable, therefore their protection is a major goal. One threat arises by intentionally defacing such with graffiti. possibility to face the imminent application of surface form anti-graffiti systems (AGS). However, knowledge about performance durability AGS on substrates used for historical buildings still fragmented. The goal present study was investigate newly developed agent comparison selection commercial agents...

Reactive powder concrete (RPC) is a fairly novel material with extraordinary strength and durability properties.Due to these properties, it increasingly being utilized for external façade cladding thus enabling considerable reduction in the thickness of elements.Commercial RPC formulations on market are usually expensive less sustainable due high cement clinker contents.In this study, improved higher amounts supplementary cementitious materials (SCMs) were developed.The combined different...

Abstract Natural stone has been used for centuries as building material. In historical time it was mainly load bearing elements, but within the past 50 years a new processing technique made commercially feasible to produce and use thin façade cladding. Unfortunately, number of marble facades on buildings in both Europe elsewhere have had serious problems with deterioration The TEAM (TEAM = TEsting Assessment Marble limestone) project consortium represents nine European countries comprises 16...

The water absorption of crushed concrete aggregates (CCA) has a major influence on workability. In order to determine the CCA, more porous material than natural aggregates, modifications standard pycnometer method are proposed as: (1) Water is measured combined fraction CCA consisting fine and coarse proportioned according recipe. (2) pre-processed mitigate sedimentation. (3) Saturated surface dry condition aggregate assessed by vacuum filtration ocular technique. development at 0 min, 15 24...

Concrete with crushed concrete aggregates (CCA) shows lesser compressive strength than reference natural aggregates. The goal of this study is to improve the structural 53% and 100% CCA replacements without increasing cement content. Thus, improvements in quality are induced by combining mechanical pre-soaking pre-processing techniques. Mechanical rotating drum separately pursued on fine coarse for 10 15 min respectively. Results show, adhered mortar content water absorption reduces as...

Abstract The use of natural stone as facade cladding has been shown to have much lower life cycle costs and they are more environmentally friendly than comparable products concrete, glass, steel. Promoting the therefore a great positive impact on environment. However, number occurrences bowing expansion marble limestone panels led increased maintenance costs, significant safety risk, negative publicity. lack knowledge solution problem large effect entire trade. In response, short-sighted...

<p>In this paper, both experimental and numerical methods are presented to gain an understanding of the structural behaviour related a TRC sandwich panel with glass fibre reinforced polymer (GFRP) plate connection system. Double shear tests were conducted on component-scale panels characterize available capacity provided by connectors configuration. Three-dimension (3D) non-linear Finite Element Analysis (NLFEA) was applied develop model for design while focusing connectors. The...

Natural stone has been used as a building material for centuries. In the past, load bearing members were made of entirely stone, but in last 50 years new processing techniques have production and use thin facade cladding profitable venture. Unfortunately however, marble facades on buildings Europe elsewhere undergone severe deterioration. The EC-financed TEAM project (2000-2005) studied bowing observed both cold warm climates. TEAM’s main objectives to understand explain expansion, bowing,...

This paper investigates the fracture mechanical properties of concrete, using crushed concrete aggregates (CCA) and granulated blast furnace slag (GGBS) for partial cement replacement. CCAs made from prefabricated replace 100% fine coarse fractions in recipes with w/c ratios 0.42 0.48. Two pre-treatment methods, pre-processing (MPCCA) accelerated carbonation (CO2CCA), are investigated quality improvements CCA. The resulting show an increased density, contributing to increase concrete's...

Abstract Addition of fly ash or GGBS in concrete has shown to increase the durability and thus service life structures exposed chlorides. Currently, relies on regulations, which beside a minimum cover thickness also put constraint amount type SCM different environments. Swedish regulations do not, however, consider actual binders. As consequence, LCA might be misleading. This paper investigates climate impact with chloride environment. Current prescriptive design approach is compared...
