The Effect of Re-Dispersible Polymer Powders on Cement-Based Self-Leveling Mortar

摘要

The current paper experimentally investigated the effect of different kinds re-dispersible polymer powers (RPP) on cement-based self-leveling mortars. The construction operation of mortar and its mechanical property was tested in accordance with the standard JC/T 981-2005. Besides, the micro-structure surface of self leveling mortar was characterized by means of SEM to reflect the microscopic mechanism of the performance. The results showed the dispersible polymer powders could significantly improve performance of fluidity, adhesion property and abrasion resistance on cement-based self-leveling mortar;;Meanwhile, there is no bad impact on its compressive strength and flexural strength. This study has guiding significance for the construction and application of cement based self-leveling mortar.
