Abstract

Abstract

To confine concrete with fiber-reinforced polymer (FRP) can greatly improve the mechanical properties of concrete, which has been used in some application. However, the brittle failure of concrete confined with FRP restricted its application in some fields. To solve the problem, chopped basalt fiber (BF) was mixed to concrete while confining concrete with basalt fiber-reinforced polymer (BFRP) composites. By changing the number of BFRP layers and the volume content of BF, the mechanical properties of basalt-fiber-reinforced concrete confined with BFRP were studied experimentally. The results showed that the compressive strength and the maximum flexural resistance of the concrete increased with the increase of the number of BFRP layers, and the addition of BF could not only improve the strength of concrete but also the toughness of the concrete, changing the failure mode from brittle failure to plastic failure. The best performances of BF concrete confined with BFRP were at the BF content of 0.1%. Therefore, the addition of BF to concrete confined with BFRP could not only improve its mechanical properties but also its failure mode.
