CH700 is a polymeric liquid used to increase the adhesion of new concrete or mortar to old concrete or mortar. This adhesive creates concrete and interconnected layers of concrete to resist adverse weather conditions and vibration movements, while preventing water seepage and separation of fine and coarse grains.
Properties and effects:
Prevent cracking or drumming
Repair of concrete surfaces
Increase durability against destructive environmental factors
Sealing of restorative mortars
Glue the dried concrete surface to fresh
Filling cracks and seams in concrete
Showcase and execution of exposure surfaces
Concrete making method:
Depending on the amount of adhesion required, the type of granulation and mixing plan of concrete or mortar, 5 to 20% of the weight of cement used is added to the dry concrete components. If the mixing plan is fine-grained, the amount of concrete adhesive should be less and if the mixing plan is coarse, the amount of concrete adhesive should be used more. Note: In order to determine the exact amount of consumption in both slurry methods and adding to the mixture, it is necessary to perform workshop tests.
Method of Use:
As with all adhesives, surface preparation is very important. The surface should be thoroughly clean and free of grease, loose particles and dust. Water should accumulate on the surface under the work before application.
Concrete adhesive can be used in two general ways to increase adhesion and remove seams.
Add to mixture
In this method, you must first use the saturated sections using saturated water, then pour the adhesive slurry with a thickness of approximately 1 to 2 mm on the sections and concreting the slurry before it hardens.
How to make slurry: Polymer slurry is prepared by mixing concrete, water and cement adhesives in a weight ratio of 1-1-4. About 1.5 kg of polymer slurry is required to cover each square meter.
Add to mixture
Method of making adhesive mortar: Depending on the amount of adhesion, the concrete adhesive can be mixed with water in a ratio of 1: 4 to 1: 3 and the resulting adhesive diluted to other components of the mortar until the required amount of workability (optimal flow rate) is reached. Add.
