Thermal insulation of crumb-rubber mortar for building walls application
Abstrak
This research work reveals that the thermal properties of cement mortar are significantly affected with increase in crumb-rubber content, when used to partially replace sand in cement mortar mixes. The work is based on experimental study with replacement made at 5%, 10%, 15%, 20% and 25% crumb rubber by volume. Thermal properties were measured base on the transient line heat source (TLS) method using a KD 2 Pro-thermal analyzer. Thermal properties most especially the thermal conductivity of cement mortar (1.286W/mk) was greatly reduced to 0.351W/mk indicating 72.7% reduction with 25% crumb-rubber particles content, which makes it a better insulator. The specific heat capacity of cement mortar (2.791 MJ/m3.k) was reduced to 1.424MJ/m3k indicating 49% reduction with 25% rubber content, which may adversely reduce thermal mass effect. Other thermal properties such as thermal resistivity increased by 72.7%, thermal diffusivity decreased by 46.4% while thermal effusivity decreases by 66.4%.These results indicates that the potential use of such a composite material as an insulating mortar for building applications is viable.
