POLYMER CEMENT COMPOSITION AND CEMENTING METHOD
To provide a polymer cement composition which, when hardened, is less susceptible to cracking by oil such as petroleum, and a cementing method using it. A polymer cement composition comprising cement, a polymer and water, wherein the polymer is a fluorinated polymer, and the degree of swelling obtained by the following measuring method is from 0 to 30%. (Method for measuring degree of swelling): A 1 mm-thick sheet made of the polymer is immersed in kerosene at a temperature within a range of 23±2° C. for 24 hours, whereby the volume change (%) as between before and after the immersion is measured, and the measured value is taken as the degree of swelling.
