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 (7)

1 . A composition of superhydrophobic concrete, comprising:

a heat-treated mixture comprising superhydrophobic graphene and aragonite in a mixture with engineered cementitious composites.

2 . The composition of claim 1 , wherein the mixture comprises 0.1-100 kg of the superhydrophobic graphene for every 10,000 kilograms of engineered cementitious composites.

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

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

5 . The composition of claim 4 , wherein the modified aragonite particles have an average particle diameter of between 100 nm and 10 μm.

6 . The composition of claim 1 , wherein the mixture is a deoxygenized mixture.
