Experimental evaluation of green engineered cementitious composites.

Engineered Cementitious Composites (ECCs), also known as bendable concrete, are special type offiber-reinforced materials that possess strain-hardening capabilities and compared to materials such asFRPs, have far higher bending and tensile strengths. The tests carried out in this study include slump tests,as well as tests concerning the mechanical properties of hardened concrete, namely compressive tests,bending tests.The results show that the mixture design containing 75% PVA fibers has the highest averagecompressive strength, yielding 28-day and 90-day compressive strengths of 72.18 MPa and 88.84 MPa,respectively. The highest 28-day and 90-day bending strengths are equal to, respectively, 12.85 MPa and14.91 MPa, and correspond to the mixture design with 1% of fiber content. These values indicate an increaseof roughly 27.75% compared to the control mixture design. Adding fibers to the mixture improves thetensile strength and hardening behavior of ECCs. Considering that the material is used instead of cement,it can be called green concrete.
