Abstract: With the current demand for portland cement concrete (PCC) sustainability, supplementary cementitious materials (SCMs) are often used in concrete mixtures to improve the mixture properties in both fresh and hardened concrete. ...

Abstract: Considerable interest has been directed in recent years toward the use of self-healing materials in concrete. The concept of microcapsule healing is based on a healing agent being encapsulated and embedded in the concrete. ...

Abstract: This paper presents an evaluation of dual self-healing mechanisms in concrete, with a focus on the application of microcapsules and shape memory alloy (SMA). To achieve this objective, the study evaluated the self-healing ...

Abstract: Healing capabilities of shape-memory alloys (SMAs) and steel-reinforced mortar with self-healing microcapsules were investigated. Small cracks ranging from 13 to 152 μm were induced by three-point bending, and specimens ...

Abstract: Mechanisms of flexible pavement fatigue cracking and reflective cracking from a cement-treated base (CTB) layer were investigated. 3D finite-element (FE) models were developed to simulate typical pavement structures for ...
