Analysis of Curing and Mechanical Performance of Pre-Impregnated Carbon Fibers Cured within Concrete
Publikováno v:
Textiles, Vol 2, Iss 4, Pp 657-672 (2022)
In carbon-reinforced concrete, the commonly used steel reinforcement is replaced with carbon fiber reinforcement textiles, enabling thin-walled elements by using new construction principles. The high drapability of textiles offers design opportunitie

One of the promising technologies to produce carbon textile-reinforced concrete structures is extrusion. For defect-free extrusion, high requirements are placed on the fresh concrete, since it must be transportable through the augers in the extruder

Calcined mixed clays are one of the most promising alternative supplementary cementitious materials. However, their standardized use is difficult due to the wide range of compositions of the raw materials. The reactivity potential of different clays

Concrete structures without sufficient durability can be damaged by sulfates in groundwater and from surrounding rock layers. To evaluate the performance of a concrete mixture, precise and performance-oriented test methods are a must. Therefore, a ne

To reduce resource consumption and the carbon footprint of the construction industry, new construction principles that stipulate the minimisation of materials are urgently needed. Floor slabs show high potential for saving materials and CO2 emissions

To produce defect-free extruded and shaped components, the forming behaviour of extruded fibre-reinforced mortar mixtures, impregnated textiles and extruded textile-reinforced mortar (TRM) was investigated. The TRM test specimens were formed longitud

The in-situ measurement of the content and orientation of steel fibres in concrete structures is of great importance for the assessment of their specific mechanical properties, especially in the case of repair. For existing structures, the actual fib

The diagnostics of constructions built with steel fibre reinforced concrete are extremely difficult to conduct because, typically, no information on the actual amount and orientation of the fibres is available. Therefore, it is of great interest to e

A promising process for the automatization of concrete structures is extrusion or extrusion molding. An innovative approach is the extrusion of concrete with imbedded technical textiles as reinforcement. For a successful extrusion, the rheological pr

The European standard EN 206-1 contains descriptive requirements for concrete to withstand sulfate attack in the field. This approach limits the use of feasible concrete mixtures that don’t comply with these requirements. A performance approach bas
