Luagent is an auxiliary material for the construction of concrete concrete pavement.Uniform spraying on the newly paved concrete surface and covering the plastic film health, so that 2-6mm mortar does not condense for a certain time, when the internal concrete condensate reaches a certain strength, brush the surface mortar, can expose the thick aggregate with a height of 1-3mm, forming a exposed concrete with rich texture and uniform surface texture.The dew depth of Lulu cement pavement is 1-2mm, and the dew depth of exposed concrete deck slab is 2-4mm, which can be controlled by adjusting the amount of Lulu agent sprinkling and washing time.
