Mechanical behaviour of fibre reinforced concrete using shape memory alloys

Abstract

Usage of smart materials in concrete is extensively increasing. This study focuses on behavior of fiber reinforced concrete, using shape memory alloys (SMA) fibers. SMA adopted for this study is NiTi shape memory alloy crystals. Concrete is tested for slump and mechanical properties tested are compressive strength for 7 and 28 days. Flexural strength is tested for 28 days. Constant rates of 1% of SMA fibers are added to the concrete mix. Also regular steel fiber reinforced is prepared and test values are compared with SMA fiber reinforced concrete.
