Abstract

A method of making superhydrophobic concrete includes creating a mixture, wherein the mixture comprises aragonite and/or graphene, and heating the mixture to a temperature between 500° C. and 2,500° C., then drying the mixture, and, optionally, adding the mixture to concrete.

Claims (11)

1. A method of reducing water penetration for concrete, the method comprising:

creating a mixture, wherein the mixture comprises aragonite, engineered cementitious composites (ECCs), and superhydrophobic graphene;

heating the mixture to a temperature between 500° C. and 2,500° C.;

drying the mixture; and

adding the mixture to concrete.

2. The method of claim 1 , further comprising removing oxygen from the mixture before adding the mixture to concrete.

3. The method of claim 1 , wherein the mixture comprises 0.1-100 kg of graphene for every 10,000 kilograms of concrete.

4. The method of claim 1 , wherein aragonite is added in a quantity less than graphene.

5. The method of claim 1 , wherein the method results in less quarry calcium carbonate in concrete than traditional concrete production.

6. The method of claim 1 , wherein the aragonite comprises modified aragonite particles formed from restructured oolitic aragonite that have an average diameter less than or equal to 10 μm.

7. The method of claim 6 , wherein the modified aragonite particles have an average particle diameter of between 100 nm and 10 μm.
