Abstract

Chemical-resistant polymer concrete and methods of use thereof are described herein. The polymer concrete comprises a polymer layer and aggregates. The polymer layer is formed by reacting an epoxy vinyl ester resin promoted with cobalt and catalyzed by a peroxide. A concrete substrate is formed by layering the polymer layer and aggregates in thin alternating layers until a desired thickness is achieved. This layering method can reduce shrinkage of the concrete, thereby preventing cracking, deformation or debonding.

Claims (12)

1 . A concrete composition comprising alternating layers of polymer ( 110 ) and aggregate material ( 120 ).

2 . The concrete composition of claim 1 , wherein a number of layers ( 105 ) ranges from 2 to 40.

3 . The concrete composition of claim 1 , wherein the composition is acid resistant

4 . The concrete composition of claim 1 , wherein the polymer comprises at least 90 wt % of a vinyl ester resin, and about 0.5 wt % to about 5 wt % of peroxide.

5 . The concrete composition of claim 4 , wherein the polymer composition further comprises about 0.05 wt % to about 0.5 wt % of a promoter.

6 . The concrete composition of claim 1 , wherein the polymer comprises at least 90 wt % of an epoxy or polyurethane resin.

7 . The concrete composition of claim 1 , wherein the aggregate material ( 120 ) comprises quartz, silica, or a combination thereof.

8 . The concrete composition of claim 1 , wherein the aggregate material ( 120 ) has a grit size of about 16 grit to about 60 grit.

9 . The concrete composition of claim 1 , wherein a thickness of each composite layer ranges from about 1 mm to about 9 mm.

10 . The concrete composition of claim 1 , further comprising a reinforcing material ( 140 ) disposed in at least one of the composite layers ( 105 ).

11 . The concrete composition of claim 10 , wherein in the reinforcing material ( 140 ) comprises carbon or glass fabric or rods.

12 . The concrete composition of claim 10 , wherein the reinforcing material ( 140 ) is disposed between the polymer ( 110 ) and the aggregate material ( 120 ).
