There may be cracks in epoxy floor during construction, but there are many reasons. This phenomenon occurs, but the control measures are basically the same. Construction joint treatment, temperature stress crack treatment and expansion joint treatment are commonly used methods. The base types commonly used in ground construction are concrete ground, cement mortar ground and terrazzo ground, which have wide sources, low viscosity, good grouting ability, strong diffusion ability, convenient construction and high mechanical strength, and can resist most chemical erosion of concrete.
Construction Joint Treatment of Epoxy Floor
The construction joints are not real "joints", but the joints between the concrete poured after the initial setting time and the concrete poured according to the design requirements or construction needs.
Treatment of Thermal Stress Cracks in Floor
Temperature stress cracks often occur in concrete floor construction. The main cause of these cracks is the excessive temperature difference between the foundation and concrete or the stress release caused by other reasons. According to the different performance, it can be divided into surface crack, deep crack and through crack.
Under certain conditions, surface crack develops into deep crack and deep crack develops into penetrating crack. Therefore, if cracks are not repaired in time, the decorative effect of epoxy floor will be directly affected.
Treatment of expansion joint of epoxy floor
According to the structure layout, geological conditions and construction layout, construction intensity and other transverse joints in the structure, in order to meet the requirements of structural deformation, there should be no rigid filler between joints. Because the expansion joints need to meet the stress changes of the whole building, elastic materials are needed for the treatment of expansion joints, and metal sheets are laid outside to protect them.
