Liquid additive for cement resiliency

A cement composition including: a hydraulic cement; at least a sufficient concentration of water to form a pumpable slurry with the hydraulic cement; a polymer selected from the group consisting of: (i) a homopolymer of one monomer selected from the group consisting of: N isopropylacrylamide, N propylacrylamide, and N,N diethylacrylamide; (ii) a copolymer consisting of two or more monomers selected from the group consisting of: N isopropylacrylamide, N propylacrylamide, and N,N diethylacrylamide; and (iii) a copolymer comprising: one or more first monomers selected from the group consisting of: N isopropylacrylamide, N propylacrylamide, N,N diethylacrylamide, and any combination thereof; one or more second monomers selected from the group consisting of: acrylamide, an acrylamide derivative other than one of the first monomers, methacrylamide, an N alkylmethacrylamide, N-methyl-N-vinylacetamide, N-vinylformamide, a vinylpyrrolidone, a vinylpyridine, N-vinylcaprolactam, N-methyl-N-vinylacetamide, a styrene sulfonic acid, a styrenesulfonate, a vinylsulfonic acid, a vinylulfonate, and any combination thereof.
