| Concrete Bonding Agents |
Concrete bonding
agents are used for joining new and old surfaces and these chemicals help in
joining different surfaces and act like a single unit. These concrete bonding
agents increase the performance and strength of the structure.
Cleanliness of the
existing surface and surface preparation are two factors which affect bonding of
old and new concrete. Bonding agents can help in reducing cracks which are
formed due to shrinkage. These bonding agents also improve adhesion between
different layers of concrete and these bonding agents are flexural, tensile in
nature. Bonding agents exhibit high resistance from frost and different
chemical actions.
Bonding agents provide
a great adhesion and workability in between old and new concrete structures.
Applying bonding agents, can improve the tensile strength of various joints.
These bonding agents also reduce the risk of cracking and they are very easy to
apply and use.
There are several
types of concrete bonding agents. Roc Prim is a two-part epoxy resin concrete
adhesive that is mixed on site and bonds two dry layers together while providing
a moisture barrier between the layers. Placeo Cemcol is an extremely strong
concrete bonding agent and is best used for surfaces containing hard aggregates
and heavy traffic. It is supplied in powder form and mixed on site before it is
applied to the drenched concrete slab.
Concrete
Bonding Agents have various
applications in flooring and decorative applications. Due to their high bond
strength and flexibility, they are preferred over other materials for flooring.
Concrete bonding agents also increase the flexural and compressive strength of
cementitious systems. Therefore, their growing use in construction is expected
to continue into the future.
These concrete binding
agents have various decorative applications. These binding agents are fueling
the global market for concrete bonding agents. Increasing living standards in
emerging economies are increasing the demand for decorative applications. Easy
to use applications of concrete bonding agents support the industry.
There are different
types of concrete bonding agents for various purposes. Some of them are
re-emulsifiable while others are not. Binding agents can be chosen from a wide
variety, depending upon the application. It is important to use a clean surface
to apply the bonding agent because a dirty surface will not adhere to the
material well. Pressure washing and vacuum shot blasting will help you achieve
this task.
Increasing
construction activity in emerging economies such as India and China is also
estimated to grow use of concrete bonding agents. Moreover, the use of concrete
in construction activities is a growing trend worldwide. The development of
urbanization and increasing disposable income in different countries has been
noticed. Poor workmanship and lack of awareness are the other challenges in the
development of concrete bonding agents.
Three types of bonding
agents are found, Epoxy bonding agents, Polyvinyl acetate and Acrylic latex
bonding agents. Epoxy bonding agents are mostly used for lightweight structures
and provide higher compressive strength. Acrylic latexes contain 45% solids and
these can be applied to trowels and brushes. Polyvinyl acetate is used for
reducing permeability and also provides great water resistivity.
