Quartz Sand Thermal Conductivity

Dec 12 2015018332in this research thermal conductivities of three quartz sands were studied using a newly developed thermotime domain reflectometry tdr probe the test results revealed that thermal conductivity of quartz sands increased with compaction moisture content and dry unit weight higher quartz content also led to higher thermal conductivity.

We are committed to building crushing, industrial grinding, ore processing and green building materials, and provides intelligent solutions and mature supporting products.
