Abstract
Methods are generally provided for forming a polymer-cement composite. In one embodiment of the method, a plurality of dopamine monomers is dispersed in a buffer solution. Polymerization of the dopamine monomers can then be initiated, and a cement-sand mixture can be added to the buffer solution to form a composite mixture. Finally, the composite mixture can be cured to form a polymer-cement composite. Polymer-cement composites are also generally provided that, in one embodiment, include cement, sand, and poly(dopamine), with the polymer-cement composite having a compressive strength of 8000 psi.
