Lightweight Panels of Steel Fiber-Reinforced Self-Compacting Concrete

Abstract

No presente artigo, é descrito um método de concepção para betão auto-compactável reforçado com fibras de aço (BACRFA) de custo competitivo, a ser usado na indústria de pré-fabricação. Uma das questões mais importantes na indústria da pré-fabricação é a da descofragem dos elementos, que deve ser feita com a maior brevidade possível. Deste modo, foi levado a cabo um programa experimental para estimar a influência da idade na resistência e na ductilidade do BACRFA desenvolvido. A relação tensão-abertura de fenda foi determinada com base na relação força-flecha obtida em ensaios realizados segundo as recomendações da RILEM (TC 162-TDF). Foi analisada a influência da idade do BACRFA nos parâmetros de fractura deste material. Foi analisada a influência da idade do BACRFA nos parâmetros de fractura deste material.

Development of sandwich panels combining fibre reinforced concrete layers and fibre reinforced polymer connectors. Part I: Conception and pull-out tests

“…SFRSCC was also suggested as the material for sandwich panels, in which the connection between the concrete layers is assured by solid zones of concrete [17]. Nevertheless, the combination of SFRSCC panels with FRP connectors to obtain a sandwich panel that takes advantage of both materials is unknown at present phase, thus motivating the research reported herein.…”

Development of sandwich panels combining fibre reinforced concrete layers and fibre reinforced polymer connectors. Part II: Evaluation of mechanical behaviour

“…This panel comprises Glass Fibre Reinforced Polymer (GFRP) connectors and two thin outer layers of Steel Fibre Reinforced Self-Compacting Concrete (SFRSCC). Although different types of FRP connectors have been already investigated for reinforced/prestressed concrete sandwich panels [2][3][4][5][6] and the SFRSCC was suggested as the material for sandwich panels [7], the combination of FRP and SFRSCC to obtain a sandwich panel that takes advantage of both materials is unknown at present phase.…”

The High Temperature Effect on Fibre Reinforced Self Compacting Lightweight Concrete Designed with Single and Hybrid Fibres

“…They conducted out compressive and exural strength tests besides durability tests such as freezing-thawing, carbonation etc. Barros (579) et al [14] made a study on lightweight panels of steelbre reinforced self compacting concrete. They analysed the inuence of the age on the steel bre reinforced self compacting concrete fracture parameters.…”
