E.M.BOND Concrete adhesive

Lack of adhesion of new cement mixtures to old cement mixtures is one of the significant and worrying workshop issues for construction project participants. Concrete cutting sites (executive and cold joints) have always been in the spotlight in this regard.

Lack of adhesion of new cement mixtures to old cement mixtures is one of the significant and worrying workshop issues for construction project participants. Concrete cutting sites (executive and cold joints) have always been in the spotlight in this regard.


Concrete adhesive


If the integrity of the concrete is not maintained due to practical reasons in the sections under concreting, cold joints are formed in the concrete, which is observed during operation, fluid passage or leakage. The main reasons for the occurrence of cold joints are the extreme heat of the air and the acceleration of the setting of the concreted area with side sections.

Of course, delays in the construction, transportation and placement of concrete along with sections that have already been concreted are other reasons for the occurrence of cold joints. In this way, a proper internal connection between the components of the concrete will not be established and cold joints will be created in such joints. These weak sections cause irreparable damage to the building reinforcement and durability of the structure, and the severity of the corrosion phenomenon in these sections causes economic damage and thus reduces the useful life of the structure.

The science of building chemistry has provided simple and various executive solutions to help eliminate the mentioned quality limitations by using various types of concrete bonding chemicals. Abadgaran Company, as a knowledge-based industrial group, due to its significant expertise and experience in providing services to construction projects, designs and manufactures these bonding materials by designing and producing a powerful polymer called concrete adhesive (EMBOND) with the aim of increasing strength. Provides adhesion between two layers of old and new concrete.

E.M.BOND concrete adhesive

EMBOND concrete adhesive is a thick polymer emulsion that is used to increase the adhesion of new concrete or mortar to old concrete or mortar and in addition to increasing the adhesion strength, will reduce the permeability of concrete or mortar can also be used for Used rebar planting. This material is soluble in water before drying and will not dissolve in water after drying. Therefore, while facilitating consumption due to easy mixing with cement mixtures, it will lead to maintaining quality properties equal to the useful life of the structure.

This material, while increasing the adhesion of new concrete or mortar to old concrete or mortar, prevents cracking or drumming and reduces permeability. Quality stability in alkaline environments and reduction of shrinkage with the possibility of reducing the ratio of water consumption are other benefits of E.M.BOND material.

E.M.BOND material is used to repair surface damage, strengthen adhesion, seal repair mortars, as well as show and perform exposure surfaces.

How to use E.M.BOND concrete adhesive

Before using E.M.BOND, the surface of old concrete or substrate must be thoroughly clean and free of grease, loose particles and dust. It is also recommended that the following sections be saturated with fresh water. Accumulation of water on the substrate surface should be avoided before application. E.M.BOND can be used in two general ways to increase adhesion and remove cold seams:

Slurry method
Adding to the mixture of the slurry method: In this method, first the desired sections should be saturated with fresh water, then the adhesive slurry with a thickness of approximately 1 to 2 mm should be poured on the saturated sections and before the slurry hardens (so that after Avoid pressing on the finger

How to make slurry
The polymer slurry is prepared by mixing E.M.BOND water and cement in a weight ratio of 1-1-4. About 1.5 kg of polymer slurry is required to cover each square meter. In this slurry, 250 grams of E.M.BOND concrete adhesive has been used.

Attention
Never use concentrated concrete adhesive liquid alone to bond concrete sections together.

Add to mixture
Method of making adhesive mortar: Depending on the amount of adhesion, concrete adhesive can be mixed with water in a ratio of 1: 4, to 1 to 3 and the resulting adhesive can be added to other components of the mortar until the required amount of workability (desired psychological value) ) Add.

How to make sticky concrete

Depending on the amount of adhesion required, the type of aggregation and the mixing plan of concrete or mortar, 10 to 40% of the used water is replaced and added to the dry components of the concrete. It is recommended to use less concrete adhesive if the mixing plan is fine-grained and more concrete if the mixing plan is coarse.

Important Note: Determining the exact amount of consumption in both slurry methods and adding to the mixture is required through workshop tests.
