Self-compacting fibre reinforced concrete applied in thin plates

Abstract

Floor panels produced with traditionally vibrated concrete are relatively thick due to the need to reinforce concrete and consequently, heavy. Without the need to place rebars in panels and by applying self-compacting fibre reinforced concrete (SCFRC) the production process becomes more efficient. Fibres improve the performance of concrete by counteracting the crack-growth during loading. Their efficiency also epends on how they are distributed and oriented in a cementitious matrix. This paper describes a study on the application of thin plates with self-compacting concrete with and without fibres for floors; other materials like steel or wood often are applied for this application. Six concrete panels (dimensions: 600-600-15 mm3 ) were tested in this study; no rebars were placed in the elements. Self-compacting concrete was applied and the dosage of steel fibres was varied (0; 0,99 and 1,97 Vot.-%). The plates were tested by point-loading; the failure pattern depended on the fibre dosage.Structural EngineeringCivil Engineering and Geoscience
