Polymer cement composition and cementing method
The present invention provides a polymer cement composition and a cementing method in which the same is used. The polymer cement composition is not easily cracked due to oil such as petroleum when cured. The polymer cement composition contains cement, a polymer, and water. The polymer is a fluorine polymer. The degree of swelling obtained using the following measurement method is 0-30%. (Method for measuring the degree of swelling) A 1 mm-thick sheet made of the polymer is immersed in kerosene at a temperature in a range of 23±2°C for 24 hours, the volume change ratio (%) before and after the immersion is measured, and the value is used as the degree of swelling.
