Experimental Study on Thermal Conductivity of Road Concrete

Abstract:

In order to analyses affection to thermal conductivity from various factors, such as: coarse aggregate, mortar ratio, sand ratio, water cement ratio, fly ash and air content, thermal conductivity of a series of concrete specimens were determined based on thermal conductivity meter. The results showed that: coarse aggregate, mortar ratio and gas content is the main factor affecting concrete thermal conductivity. Meanwhile, water-cement ratio, sand ratio and fly ash had few effects on the thermal conductivity. In addition, a certain formula to predict thermal conductivity of concrete was proposed.
