Material Properties of Cement Paste with Addition of Fly Ash Exposed to High Temperatures

摘要

Properties of cement pastes are significant to the assumption behavior of concrete and concrete structures. Material properties are essential properties. This paper presents the results of research material properties of cement pastes containing fly ash. The compressive strength and modulus of elasticity is presented. The changes occur in the properties of the material, which is exposed to the effect of high temperatures. Therefore, the article focused on the change of properties trap with fly ash after exposure to temperatures up to 600 ℃.
