Flexural Behaviour Of Strengthened RC Beams With Multi-Directional Basalt Fibre - Reinforced Polymer Composites

Abstract

The paper describes an experimental behaviour of the basalt fibre reinforced polymer composite by external strengthening to the concrete beams. The BFRP composite is wrapped at the bottom face of R.C beam as one layer, two layers, three layers and four layers. The different characteristics -are studied in -first crack load ,ultimate load, tensile and compressive strain, cracks propagation, crack spacing and number of cracks etc.To -investigate, total of five beams size 100mmx 160mmx1700mm were cast. One beam is taken as control and others are strengthened with BFRP composite with layers. From this investigation, the first crack load is increased depending on the increment in layers from 6.79% to 47.98%. Similarly, the ultimate load carryingcapacity is increased from 5.66% to 20%. The crack's spacing is also reduced with an increase in the number of layers

Bending Resistance and Failure Type Evaluation of Basalt Fiber RPC Beam Affected by Notch and Interfacial Damage Using Acoustic Emission

“…Previous studies [10][11][12][13][14][15] have indicated that BF could increase the bending ductility, bending resistance, shear strength, and bearing capacity of concrete beams. Garcia et al [16] and Chandran et al [17] used BF composite materials to reinforce the wooden and concrete beams, respectively. Krassowska et al [18] found that BF had the ability to transmit shear stress in the beam structure.…”

Durability of concrete pavement strengthened with asphalt layer with FRP fibres

“…This can be achieved by applying polypropylene [5], polypropylenearamid, carbon, polyester, or cellulose fibres to the asphalt concrete mixture [6]. In civil engineering, reinforced polymer composites are increasingly used [7,8,9,10,11]. A new technological solution is the modification of the asphalt mixture with innovative basalt-polymer FRP (Fiber Reinforced Polymer) fibers [3].…”
