Abstract: The construction sector produces thousands of tons of construction and demolition waste annually, which motivates us to focus on recycling this waste. In view of obtaining a circular economy, recycled concrete from Morocco has been used as filler. Recycling construction and demolition wastes (CDW) as aggregates replacing natural aggregates for concrete is a solution that deserves to be evaluated.
For this fact, it would be interesting to study the characterization of the thermo-physical properties in relation to their capacity of heat transfer for composite materials. Because of its many uses as thermal insulators in the fields of buildings, this is one of the current subjects of study.
The aim of this work is therefore to study the thermal conductivity, specific thermal density, thermal diffusivity and effusivity of a composite material with a quantity of recycled aggregates from 0% to 20% at different temperatures
It is concluded that the thermal properties of the recycled aggregate of concrete can be used in the same applications as the conventional concrete. |
Keywords and phrases: concrete, recycled aggregate, recycling concrete to concrete, thermal conductivity, thermal diffusivity, specific heat density, thermal effusivity.
