Epoxy grout manufacturer share crack treatment techniques

common ground floor construction basic types have a concrete, cement mortar ground and terrazzo floor, has wide sources, low viscosity, can be good, good diffusion, construction convenient, high mechanical strength, and can resist the most concrete have encountered chemical erosion of epoxy floor paint in construction process, there may be a crack phenomenon occurred, although there are many reasons lead to the occurrence of this phenomenon, but in the aspect of prevention and improvement measures is roughly same, often using construction joint treatment, temperature stress crack, expansion joint processing of targeted treatment.

1, construction joint treatment.

construction joints are not real & other; Seam & throughout; , it is according to the requirements of design or construction need more than the initial setting time and after pouring concrete pouring concrete between a first joint surface.

2, temperature stress fracture treatment.

in the concrete floor can often be found in the construction process of the temperature stress crack, the principal causes of the cracks is due to the large foundation temperature difference and concrete inside and outside temperature difference stress release or due to other reasons, according to the form of different can be divided into the surface again, deep cracks, transfixion crack 3 kinds. Under certain conditions, the surface cracks will develop into deep cracks and deep cracks will develop through the cracks, so if not in time to repair cracks, will directly affect the epoxy floor adornment effect.

3, expansion joints treatment.

according to the structure arrangement, geological conditions and construction layout, the construction intensity in the structure, such as setting the horizontal seam, in order to meet the requirement of structure deformation, joint surface between general should not be rigid filler. Because of the expansion joints need to satisfy the stress variation in the whole building, so for the expansion joint processing need elastic material, laying of sheet metal to protect outside.

the above said to the three kinds of epoxy floor paint anti-corrosive paint cracks, expansion joints and construction joints is set up to meet the stress change of concrete artificial, temperature stress crack because of the stress change of concrete itself.
