Description
technical field [0001] The invention relates to a calculation method of linear thermal expansion coefficient, in particular to a method for preparing epoxy mortar and concrete by using linear thermal expansion coefficient. Background technique [0002] Epoxy mortar is a composite material mixed with epoxy resin, curing agent and inorganic filler in a certain proportion. Structural polymers widely used in civil engineering. [0003] During the use of epoxy mortar, damage caused by temperature changes often occurs. Therefore, when using epoxy mortar, its linear thermal expansion coefficient needs to be measured, and it can be used only when it meets the relevant requirements. However, the measurement of the linear thermal expansion coefficient is a time-consuming, labor-intensive, and expensive work, and accurate measurement requires expensive instruments to achieve. Moreover, since the composition and ratio of each raw material in epoxy mortar often change, especially in th...
