Abstract
Examples of new polymer-modified cement formulations with self-healing capability at ambient temperature are described. These polymer-modified cements can be readily mixed with typical fine and coarse aggregates to build new concrete structures. One example of such a formulation includes a concrete comprising a MBA-BDA polymer having bond forming chemical functionality configured to form a bonding matrix between the polymer and at least one component of the concrete at a temperature less than 50 degrees C. wherein the matrix obtains at least 70% recovery of compressive strength after a damage event.
Claims7
A self-healing concrete comprising:
- a hyperbranched organosilicon polymer having bond forming chemical functionality configured to form bonds between the polymer and at least one component of the concrete at a temperature less than 50 degrees C.
