Error Analysis on Thermal Conductivity Measurements of Cement-stabilized Soil Blocks

Abstract

Errors exist in all measurements, as no test results are perfectly reliable upon accuracy. An attempt made in understanding the error associated in measuring the thermal conductivity of cement-stabilized soil blocks was carried out. The errors such as repeatability and material errors were assessed in the current study. Both the errors will be expressed in relative standard deviations as erepeatability and ematerial. These results can be attributed to variation in how a specimen was cast, stored, and prepared for the experiment and includes aging, material stability, and ambient exposed conditions. The results of repeatability errors were found to be low for all the materials tested. The material errors can be attributed to the material heterogeneity and the inherent characteristics of the materials.
