Abstract
In order to study the influence of temperature on compressive strength of polymer grouting material, the compression specimen injection mold is self-made, and the uniaxial compressive test was carried out in the temperature control box under different temperatures. The change regularity of compressive strength of polymer grouting material under different temperatures and the law of volume changes of polymer samples were obtained. The experimental results show that: the compressive strength of polymer material increases with the increase of density; the temperature change has a certain influence on the compressive strength of polymer grouting material; the compressive strength decreases with temperature increases under the same density, but the compressive strength is not significantly affected by temperature when the density is less than 0.4 g/cm3; the volume change of the samples accords with the law of thermal expansion and contraction when temperature changes, and the increase of the volume is obvious when it is under high temperature. The achievements will provide an important basis to the application of the polymer grouting material.
