Claims22
A concrete joint and crack sealant, the sealant comprising:
- a porous expandable skeleton comprising pores;
- and
- a filler comprising a two-way shape memory polymer (2W-SMP), wherein the filler fills the pores.
A kit for use in filling concrete joints and cracks, comprising:
- a first component and a second component, wherein the first component is to be positioned within a concrete joint or crack and after placement of the first component in concrete joint or crack, the second component is disposed within the first component, wherein forming a concrete joint and crack sealant upon disposing the second component within the first component,
- wherein the first component is a porous expandable skeleton comprising pores and the second component is a filler comprising a two-way shape memory polymer (2W-SMP), wherein the filler is used to fill the pores of the porous expandable skeleton.
20-24. (canceled)
A method for sealing a concrete joint or crack, comprising:
- inserting a porous expandable skeleton into the concrete joint or crack;
- and
- filling the skeleton with a filler comprising a two-way shape memory polymer (2W-SMP), wherein the combination of the porous expandable skeleton and the filler form a concrete joint and crack sealant.
