Effect of
Glass Wool Addition on Some Properties of Cement Mortar |
This
work presents an investigation of possible incorporation of the
glass wool (fiberglass insulation) in cement mortar as an
insulating building material. Mortar of ordinary Portland cement
of (1:3) cement to sand ratio was mixed with glass wool at
different weight percentages0 ranged between (0 – 0.24) wt%.
Density, water absorption, thermal conductivity, compressive
strength and flexural strength experimentally were investigated
for mortar specimens after curing for (28 days). The results
showed that the incorporation of glass wool decreases the
density, thermal conductivity and compressive strength, but the
flexural strength of cement mortar enhances. Thermal
conductivity of the cement mortar has decreased by about 44 % by
increasing of glass wool content up to 0.24 wt%. Thus,
utilization of glass wool as constituents in cement mortar
appears to be a promising opportunity that enables applying as
thermal insulation materials in constructions. |
