preparation example Construction
[0064] The preparation method of thin-layer pavement repair mortar provided by the invention comprises the following steps:
[0065] (1) First weigh each component according to the weight percentage of each component, then place cement, quartz sand, fiber, and water-retaining agent in the mortar mixing tank in advance, and use a portable mixer to dry mix until uniform;
[0066] (2) Then add rubber powder, water reducer, defoamer, flocculant, heavy calcium powder and water to mix through a concrete mixer, and it can be used after mixing evenly.
