Thermal insulation and mechanical properties of construction materials with nitrile rubber (NBR) waste for construction industry
Rubber waste is one of waste materials listed in the ‘First Schedule’ of scheduled waste list in Environmental Quality Regulation 2005 (Scheduled Waste). Scheduled wastes are normally associated with tight management and high cost of disposal. Conventionally, they are incinerated in combustion s...

Rubber waste is one of waste materials listed in the ‘First Schedule’ of scheduled waste list in Environmental Quality Regulation 2005 (Scheduled Waste). Scheduled wastes are normally associated with tight management and high cost of disposal. Conventionally, they are incinerated in combustion system with gases effluent treatment system. This research was aimed to investigate the effects of adding nitrile rubber (NBR) waste on the mechanical properties and thermal conductivity of clay bricks. For this investigation, mechanical tests; compression strength test and water absorption test were carried out on the samples of clay bricks impregnated with NBR waste. Samples used in this research were produced by compacting and extruding the mixture into the required size before being fired in an oven at 1060°C for ten hours.1.5 pphr of NBR waste was introduced into the standard mixture of clay bricks.
