This video briefly explains about
the what is heat, what is thermal expansion of materials, what should we
consider when choosing the flooring products.
As per ASTM C 884/C 884M – 98, Thermal Compatibility Between Concrete and an Epoxy Resin Overlay can be tested.
A layer of epoxy-sand mortar is applied to a slab of cured and dried concrete.After the epoxy has cured, the sample is subjected to five cycles of temperature change between 25°C − 21°C. Cracks near the bond line between the concrete and the epoxy mortar constitute failure of the test.
