The addition of polymeric materials greatly affects the thermal and mechanical properties of cement mortar. In this study, the use of natural rubber latex (NRL) to enhance the insulation properties of mortar was investigated. Experimental findings showed that adding NRL significantly increased the thermal conductivity of mortar, improving its insulation capabilities.
The improvement of cement mortar's thermal and mechanical properties has been greatly impacted by the addition of polymeric materials. However, polymers added to mortar shouldn't impair either its mechanical or thermal conductivity properties. The main idea of this project is to insulate buildings by reinforcing their constituent mix with natural rubber latex (NRL) to reduce thermal conductance from excessive solar radiation which causes discomfort to building occupants. Consequently, this study presents experimental findings on the influence of natural rubber latex (NRL) on the properties of NRL-modified mortar. Five varying percentages of NRL (0.5%, 1.0%, 1.5%, 2.0% and 2.5%) were added into the mortar. Properties such as thermal conductivity, water absorption capacity, compressive and flexural strengths were evaluated. In addition, scanning electron microscopy was employed for the microstructural investigation. The experimental findings demonstrated that adding 2.5% NRL to mortar increased its thermal conductivity of mortar significantly thus enhancing its insulative properties. Even though adding NRL to mortar decreased the compressive and flexural strengths of some mixes, this wasn't too substantial nor substandard. The tests that were executed demonstrate that the NRL has a huge potential to insulate cement mortar.
