1. A composition comprising: a cement component; andan amidyl pyranose component comprising an amidyl pyranose polymer represented by Formula I or II: wherein each R1 is individually H, cyano, or C1-C8 alkyl. 2. The composition of claim 1, wherein the cement component is Portland cement, a calcium sulfate, a calcium aluminate, a calcium silicate, lime or grit. 3. The composition of claim 1, wherein the amidyl pyranose component comprises an aqueous solution. 4. The composition of claim 3, wherein the aqueous solution contains about 20 wt % of the amidyl pyranose polymer. 5. The composition of claim 1, wherein each R1 is individually H, cyano, methyl, ethyl, propyl, isopropyl, n-butyl, sec-butyl, tert-butyl, n-pentyl, n-hexyl, n-heptyl, n-octyl, 2-ethylhexyl, or isomers thereof. 6. The composition of claim 1, wherein each R1 is individually H or methyl. 7. The composition of claim l, wherein the amidyl pyranose polymer further comprises a repeat unit that includes a cross-linking moiety. 8. The composition of claim 7, wherein the amidyl pyranose polymer is represented by Formula III or IV: 9. The composition of claim 1, where the amidyl pyranose polymer further comprises a repeat unit that includes a non-pyranose acrylamide moiety, wherein the amidyl pyranose polymer is represented by Formula V or VI: wherein. R2 is C1-C8 alkyl, C1-C8heteroalkyl, OR3, or NR4R5;R3 is C1-C8 alkyl or poly(alkylene glycol);R4 is H, C1-C8 alkyl, or C1-C8 heteroalkyl; andR5 is H, C1-C8 alkyl, or C1-C8 heteroalkyl. 10. The composition of claim 9, wherein R2 is OR3 where R3 is poly(alkylene glycol). 11. The composition of claim 10, wherein the poly(alkylene glycol) is poly(ethylene glycol) or polypropylene glycol). 12. The composition of claim 9, wherein R2 is nitrogen-bound taurine or a salt thereof. 13. The composition of claim 1 further comprising an aggregate component. 14. The composition of claim 1 further comprising water. 15. A method comprising combining an amidyl pyranose component with a cement component to form a modified cement mixture, wherein the amidyl pyranose component comprises an amidyl pyranose polymer represented by Formula I or II: wherein each R1 is individually H, cyano, or C1-C8 alkyl. 16. The method of claim 15, wherein the combining further comprises combining an aggregate component. 17. The method of claim 15, wherein the combining further comprises combining an aqueous component. 18. The method of claim 15, wherein the cement component is Portland cement, a calcium sulfate, a calcium aluminate, a calcium silicate, lime or grit. 19. The method of claim 15, wherein the amidyl pyranose component is in an aqueous solution. 20. The method of claim 19, wherein the aqueous amidyl pyranose component is about 20% by weight amidyl pyranose polymer solution.
