1.Product Introduction
BC type concrete road repair material is high technology product, which is of thin layer repairing concrete road surface dusting, peeling, exposed stone etc diseases. And achieved 2h open to traffic.surface disease(dusting,peeling,honeycomb,surface fracture,polygonal ground)
2.Application Range
Professional repair concrete surface diseases of various grades roads, airports, squares, parking lots, gas stations, factory floors and room floors etc. Such as peeling, dusting, surface angularity, freeze thawing, slat corrosion, honeycombs, pitting, cracking etc. It can achieve 2mm ultra-thin repair on heavy load and high flow concrete road. It don't fall off and break under the force of stretching, rolling, moving and shaking, also stable performance and long service life.
3.Core Advantage
1)Fast early strength, 2h can restore traffic.
2)High adhesion,compression,flexural strength, thin layer repair make don't break and fall off.
3)Abrasive resistance is 8-10 times of normal concrete.
4)Waterproof, anti-freeze and hydrochloric acid corrosion resistance.
5)Beautiful, Small color difference with original road surface.

5.How to repair
1).Identifying: Select area need to be repaired.
2).Cleaning:Clean out crushed stone, dust etc cleanly within area need to be repaired by high pressure blower gun.
3).Washing:Thoroughly wash area need to be repaired cleanly by high pressure water gun, It should rush mud out from operation surface when wash. .
4).Wetting: After wash cleanly by water,it should keep water in operation surface for a period time. Fully wetting operation surface, until it is no longer seep water.
5).Cleaning: Clean water out from operation surface by high pressure blower gun.(If have water,it will seriously affect material adhesive property,compressive strength and beauty)
6).Adding water: Mix material and water then stir, the effect is best when water added 17%-18%.
7).Mixing: It must fully stir evenly when stir by vertical mixer.
8).Paving:Pour mixed repair material to operation surface need repair, flattening by darby immediately
6.Package and Storage
