Thermal conductivity of concrete with recycled bricks as aggregate

摘要

The objective of determining thermal performance is to evaluate the behavior of an element of building construction when subjected to real climatic conditions. The thermal performance of concrete is expressed in terms os the thermal conductivity. Thermal ocnductivity of lightweight concrete (LC) with recycled brick as aggregate is tested in a guarded hot plate apparatus. Thred different types of LC concrete were tested. Reference concrete was made without admixture and with 350 kg/m~3 cement content. Other types of concrete were polymer content had influence on thermal conductivity of concrete. There was a reduction in thermal conductivity with reduction of cement content of with increasing polymer content.
