Ceramsite is a type of ceramic particle. Its appearance features are mostly circular or elliptical spheres, but there are also some gravel like ceramic particles that are not circular or elliptical spheres, but irregular gravel like particles. So how to prevent it from foaming after being laid on the ground?
One is to prevent adverse weather conditions such as high temperature and humidity during construction. Before construction, if the coating encounters rain, condensation, frost, etc. It should be boring first before drawing the next material; Before construction, ceramic particle pavement materials should be diluted, mixed, and left to stand for a period of time before coating. Especially for two-component pavement materials, they should have a certain curing period to prevent uneven mixing and heat generated by reverberation from causing bubbles.
Secondly, the storage of ceramic particle pavement materials should be done well, and the moisture content of the pigments, fillers, and solvents used should be strictly controlled; In the primer formula, try to avoid using soluble fillers as much as possible; The equilibrium of solvent evaporation should be coordinated to prevent excessive solvent residue; Use low-permeability substrates in high humidity environments.
The above are measures to prevent ceramic particles from foaming on the road surface. In order to avoid foaming, it is necessary to do a good job in material storage and construction stages, starting from every link of the construction process, to prevent or repair the road surface in use, so as to increase the service life of the road surface and achieve good results in road engineering efficiency.
