Abstract
Resilient cement compositions and methods of cementing using the compositions are disclosed. A resilient cement composition of the invention comprises hydraulic cement, an aqueous rubber latex and a rubber latex stabilizing surfactant comprising an iso-dodecyl alcohol ether sulfonate ethoxylated with from about 10 to about 20 moles of ethylene oxide.
Claims20
A cement composition comprising:
- a hydraulic cement;
- an aqueous rubber latex;
- and
- a rubber latex stabilizing surfactant comprising an iso-dodecyl alcohol ether sulfate ethoxylated with 10 to 20 moles of ethylene oxide, wherein the rubber latex stabilizing surfactant is present in the composition in an amount in the range of from about 0.01% to about 0.25% by weight of the aqueous rubber latex therein.

A cement composition comprising:
- a hydraulic cement;
- an aqueous rubber latex comprising aqueous cis-polyisoprene rubber latex, aqueous nitrile rubber latex, aqueous ethylene-propylene rubber latex, aqueous styrene-butadiene rubber latex, aqueous nitrile-butadiene rubber latex, aqueous butyl rubber latex, or aqueous neoprene rubber latex and present in an amount in the range of from about 5% to about 45% by weight of hydraulic cement in the composition;
- and
- a rubber latex stabilizing surfactant comprising an iso-dodecyl alcohol ether sulfate ethoxylated with 10 to 20 moles of ethylene oxide and present in the composition in an amount in the range of from about 0.01% to about 0.25% by weight of the aqueous rubber latex therein.
