RJ-10The interface adhesive is made of imported microemulsion and contains special ingredients that provide super strong adhesion,u0026nbsp; Thoroughly solve the problem of emptying the interface between new and old concrete, and have two outstanding features of water-based environmental protection and wet base construction. It is widely used in building reinforcement, repair and protection, etc. Enhanced interface control sanding and dusting.

1. Purpose:


1.u0026nbsp; Bonding new and old concrete:Used for bonding new and old concrete such as construction joints and floor leveling layers, instead of chiseling Mao, completely solve the problems of delamination and hollowing; Sand control Grey up

2.u0026nbsp;Special primer for concrete repair and reinforcement:Partial repair, beam and column reinforcement, old foundation reconstruction, painting on the concrete base layer to increase the bonding force between the repair material and the base layer to prevent falling, deterioration and corrosion.

two. Features


1.Super bonding strength< /span> :Excellent long-lasting bonding performance, which can increase the bonding strength of new and old concrete by several times. The pull-out test is all the concrete itself is damaged, and the bonding interface is intact;

2.Good crack resistance:due to low concrete An order of magnitude of elastic modulus, which can prevent micro-cracks caused by shrinkage and expansion between the concrete base layer and the surface concrete or repair mortar, thereby avoiding hollowing;

Note: Refer to the standardGB50367-2006'Specifications for the reinforcement design of concrete structures'

four. Usage
4.1Basic preparation:
(1)Grass treatment: sanding to remove the loose part of the surface of the concrete base, washing off the floating dust on the surface, and drying;
(2)The basic requirements: the basic level is firm, rough, free of cracks, dust, oil, sand, hollow, etc. So as to ensure good adhesion between the base layer and the interface glue and the laminated layer. Surface can be painted

4.2Materials and tools:
(1)Main material: type interface agent ( Acomponent, curing agent,Bcomponent, white liquid);
(2)Tools: sander, plastic bucket, roller brush or watering can Etc.. < br/>4.3u0026nbsp;Construction steps:

Do not mix too much at a time. After mixing well It’s best to use
