Investigation of carbon and acrylic fibre-reinforced mortars

Abstract

This paper presents an experimental study on the compressive, flexure, toughness and abrasion behaviours of acrylic and carbon fibre-reinforced mortars. The mechanical and physical properties of seven different composite mortars samples containing different amounts of textile fibres were compared with reference samples prepared with standard sand, cement and water. The characteristic properties of the mortars were improved by adding fibre. However, this improvement is directly related to the type and length of fibre used for reinforcing the concrete structure. Mortars containing both carbon and acrylic fibre had more compressive strength. In particular, mortars containing acrylic and carbon had 32% higher compression strength than control mortars. Sample AC1 produced with both carbon filaments and acrylic fibres has the highest compressive strength. The brittle property of mortars can be improved by reinforcing it with carbon filaments or acrylic fibres. The toughness of specimens depending on both the fibre type and the length of fibres were observed. © 2013 Sharif University of Technology. All rights reserved.
