Abstract EN
As a class of high-ductility concrete, engineered cementitious composites (ECC) have wide application prospects in engineering fields.
However, the occurrence of cracks and the limited self-healing ability hinder the development of ECC.
Rapid self-healing has important significance for ECC in reducing maintenance costs and prolonging service life, which are conducive to sustainable development of ECC.
Therefore, the aim of this paper is to enhance the self-healing property of ECC by adding light-burned magnesium oxide (MgO) and superabsorbent polymer (SAP) on the premise of maintaining the high ductility.
First, the effect of MgO and SAP on the ductility property of ECC which is the most important feature was explored with the uniaxial tensile test.
The results indicated that MgO is helpful to the strength but not conducive to the ductility of ECC, while SAP has an opposite effect.
The effects of MgO and SAP on the ductility of ECC can be balanced.
Later, the permeability test, scanning electron microscopy (SEM), and X-ray diffraction (XRD) were used to evaluate the effects of MgO and SAP on the self-healing property of ECC.
The results showed that the combined addition of MgO and SAP shows much better effect than the individual addition and can cut the healing time by half.
Overall, it is concluded that ECC with MgO and SAP have the potential for self-healing, and the ductility can also be reconciled.
