Abstract
Disclosed herein is a concrete composition comprising: a) a cement in an amount of about 25 wt % to about 70 wt % based on a total mass of dry material; b) a rubber in an amount of about 15 wt % to about 35 wt % on a total mass of dry material; and c) fine aggregates in an amount of about 10 wt % to about 35 wt % on a total mass of dry material; wherein the concrete composition is substantially free of coarse aggregates. Additionally, articles comprising the disclosed herein composition are also disclosed. Also disclosed are methods of making the compositions and the articles.

A concrete composition comprising:
- a) a cement in an amount of about 25 wt % to about 70 wt % based on a total mass of dry material;
- b) a rubber in an amount of about 15 wt % to about 35 wt % on a total mass of dry material;
- and
- c) fine aggregates in an amount of about 10 wt % to about 35 wt % on a total mass of dry material;
- wherein the concrete composition is substantially free of coarse aggregates.
An article comprising a concrete composition comprising:
- a) a cement in an amount of about 25 wt % to about 70 wt % based on a total mass of dry material;
- b) a rubber in an amount of about 15 wt % to about 35 wt % on a total mass of dry material;
- c) fine aggregates in an amount of about 10 wt % to about 35 wt % on a total mass of dry material;
- and
- d) water in an amount of about 20 wt % to about 40 wt % on a water-to-cement ratio;
- wherein the concrete composition is substantially free of coarse aggregates.
A method comprising:
- a) mixing a composition comprising:
- i) a cement in an amount of about 25 wt % to about 70 wt % based on a total mass of dry material;
