Innovative reinforcement techniques for 3D-printed concrete: The impact of shape memory alloys on flexural strength and crack mitigation
Ronak Motiani, Saha Keunang Sylvain, Sejal P. Dalal, Jay Vora, Rakesh Chaudhari
Next Materials, 2025
The flexural performance (FP) of 3D Printed Concrete (3DPC) remains a challenge due to its limitations in tensile strength and resistance to cracking. To address these issues, innovative reinforcement materials, such as Shape Memory Alloys (SMAs), which can return to their original shape upon heating or stress removal, thus closing cracks, have been explored recently. The integration of SMAs into conventional concrete has been well-documented, yet their potential in 3D-printed concrete for enhancing flexural strength and enabling crack recovery is still an emerging area of research. This study investigates the crack mitigation and FP of 3DPC beams under various reinforcement conditions. The flexural strength (f b ) was evaluated via three-point bending tests (ASTM C78), while crack mitigation was quantified using Ultrasonic Pulse Velocity (UPV, ASTM C597). The recovery mechanisms were driven by SMA superelasticity (stress-induced strain recovery) and shape memory effect (heat-activated crack closure). Initially, the behavior of unreinforced 3DPC beams was assessed, followed by the addition of fiber reinforcement (FR), and finally, the integration of SMAs. By varying the SMA's content from 0.25 % to 0.5 % by volume, the optimal dosage for enhancing the f b value, displacement recovery, and crack closure was determined. An addition of 0.5 % of SMAs showed a drastic increase in the f b value from 3.61 MPa to 8.67 MPa, which is nearly a 140 % rise. Flexural displacement recovery also improved significantly, attributed to the super elasticity and shape memory effect of SMAs, with FR plus 0.5 % SMAs beams showing a reduction in displacement from 1.97 mm to 1.27 mm, representing a 35.53 % recovery. In comparison, FR with 0.25 % SMAs achieved a 21.66 % recovery. Additionally, SMAs substantially reduced crack width and depth. FR plus 0.5 % SMAs specimens showed a 35.3 % reduction in crack width and a 31.42 % reduction in crack depth, while FR with 0.25 % SMAs showed reductions of 20.80 % in crack width and 12.48 % in crack depth. The outcome of the present study highlights the potential of SMAs to improve the load-bearing capacity, flexural displacement recovery, and crack closure of 3DPC beams, and highlighting their potential as a valuable option for future construction methods.

Experimental investigation on recycling of waste pharmaceutical blister powder as partial replacement of fine aggregate in concrete
Sejal P. Dalal, Purvang Dalal, Ronak Motiani, Vanaraj Solanki
Resources Conservation and Recycling Advances, 2022
A novel and sustainable solution to recycle the pharmaceutical blister (PB), a medical waste, by replacing them with fine aggregates in the concrete has been presented here. Recycling of waste PB is often difficult and can demand high energy consumption. In this study, the waste PB were grinded and used as replacement of fine aggregate (sand) at substitution levels of 5%, 10%, 15%, 20%, 25% and 30% by weight of sand per cubic meter of concrete. The compressive, flexural, and tensile strength as well as the water absorption of concrete mixes was investigated. Although results report a loss of compressive, flexural, and tensile strength compared to standard mix, the target design strength is achieved in all the mixes. The water absorption criterion is also met as per the codal provisions. Thus, the outcomes of the study encourage the proposed method of recycling the waste PB in concrete.
