Thermal Conductivity of ​Soil and Concrete using the Transient Line Source Technique

Published on August 5, 2020

Overview

Discussing the measurement of the thermal conductivity and resistivity of soil and concrete using the transient line source technique. The transient line source (TLS) is an ideal and standardized method for testing materials in-situ and in the lab. Thermtest’s TLS-100 thermal conductivity meter is an easy-to-use and affordable instrument used for testing soil, rocks, concrete, and polymers.

We’ll be looking at the following:

  • Why use soil and concrete samples for TLS-100
  • Advantages of using transient line source technique
  • Overview of the TLS-100 portable device and who uses it
  • Transient line source theory
  • ASTM D5334 & other thermal conductivity testing methods
  • Good practice on using the TLS-100 portable meter
  • Testing demonstration using TLS-100 and its thermal conductivity results
