Investigation of carbon and acrylic bre-reinforced mortars

This paper presents an experimental study on the compressive, exure, toughness and abrasion behaviours of acrylic and carbon bre-reinforced mortars. The mechanical and physical properties of seven dierent composite mortars samples containing dierent amounts of textile bres were compared with reference samples prepared with standard sand, cement and water. The characteristic properties of the mortars were improved by adding bre. However, this improvement is directly related to the type and length of bre used for reinforcing the concrete structure. Mortars containing both carbon and acrylic bre 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 laments and acrylic bres has the highest compressive strength. The brittle property of mortars can be improved by reinforcing it with carbon laments or acrylic bres. The toughness of specimens depending on both the bre type and the length of bres were observed.
