Abstract: A cement composition includes cement, water in an amount from about 30% to 200% by weight of cement, and an interpolymer latex in an amount from about 10% to 50% by weight of cement. The interpolymer latex includes at least one conjugated diene monomer having 4 to 8 carbon atoms in an amount from about 5% to 95% by weight of the interpolymer latex, at least one vinyl aromatic monomer having 8 to 12 carbon atoms in an amount from about 5% to 95% by weight of the interpolymer latex, and a copolymerizable functional monomer in an amount from about 0.5% to 50% by weight of the interpolymer latex. A method of making a cement composition involves placing the above ingredients in a suitable mixer well known to those of ordinary skill in the art and mixing the ingredients until they form the cement composition.
