## Abstract

Compositions including cement and an additive and methods for making compositions and/or concrete mixtures including a cement and an additive are provided.

## Claims

### Claim 1

A method comprising combining a cement and an additive, wherein the additive comprises a polymer chain segment comprising
wherein A is independently selected from SO3H, COOH, a sulfonic or carboxy salt of an alkali metal, ammonium, quaternary ammonium, an alkaline earth metal, Al3+, La3+, Ce3−, Fe3+, Cr3+, Mn2+, Cu2+, Zn2+, Pb2+, or Sn2+.

### Claim 2 (depends on 1)

The method of claim 1, wherein the additive and the cement are combined to form a concrete mixture comprising less than 5 wt-% of the additive, based on a total weight of the concrete mixture.

### Claim 3 (depends on 1)

The method of claim 1, wherein the additive and the cement are combined to form a concrete mixture comprising less than 2 wt-% of the additive, based on a total weight of the concrete mixture.

### Claim 4 (depends on 1)

The method of claim 1, wherein the additive and the cement are combined to form a concrete mixture comprising between 0.1 wt-% and 5 wt-% of the additive, based on a total weight of the concrete mixture.

### Claim 5 (depends on 1)

The method of claim 1, wherein the additive and the cement are combined to form a concrete mixture comprising between 0.1 wt-% and 1 wt-% of the additive, based on a total weight of the concrete mixture.

### Claim 6 (depends on 1)

The method of claim 1, wherein the additive comprises
wherein A is independently selected from SO3H, COOH, a sulfonic or carboxy salt of an alkali metal, ammonium, quaternary ammonium, an alkaline earth metal, Al3+, La3+, Ce3−, Fe3+, Cr3+, Mn2+, Cu2+, Zn2+, Pb2+, or Sn2+, and wherein n is an integer between 1 and 10,000.

### Claim 7 (depends on 1)
