What exactly is a concrete release agent?

A concrete release agent is definitely a compound placed on the construction design before the concrete is put in order that the template will not stick to the concrete covering following flowing, is not easy to take apart the mould or influences the end of the concrete covering. Its primary role in the template and the concrete covering to form a motion picture that will probably be separated from the two can also be known as an remoteness agent.

A water-based release agent is surely an important ancillary in the release agent and can change the water-based release agent stream and levelling; its main attribute is definitely stability to microorganisms and enzymes, which can decrease the expense of raw materials. A water-based form release agent is utilized in forms and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing industry, manufacturing form products are not only so as to let the form release to enhance productivity and extend the life of the form use. And can make the item clean, size qualified, and reduce the generation of scrap, that is an crucial additive vital to moulds and items – Water-based Concrete Release Agent.

Concrete release agent plays an crucial role in modern building construction; its main role would be to create a layer of remoteness film between the design and the concrete covering in order that the template doesn’t stick to the concrete covering in order that it is simpler to take apart the mould right after putting and to maintain the complete of the concrete covering. Here, we will introduce the types, characteristics, use and use of concrete release agent at length.

Types of concrete release agent

Concrete release brokers can be divided into several sorts based on different classification strategies, and the typical grouping methods are the subsequent:

• According to the the scope of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete release agent for tunnels and etc.
• According to the the composition: it can be divided into water-based concrete release brokers, petroleum-based concrete release representatives, silicone oil concrete release brokers, etc.
• According to the the use effect: it can be divided into ordinary concrete release representatives, an easy task to remove concrete release representatives, high-gloss concrete release brokers and so on.

Features of Concrete release agent

A concrete release agent is additionally referred to as a concrete isolation agent or mould release lubricant. It is actually a kind of material coated on the inner wall of the formwork to play the role of lubrication and isolation so that the concrete can be effortlessly detached from the formwork when taking down the formwork, and the condition of the concrete may be kept intact and undamaged. Compared with the standard release substance motor oil or waste motor oil, the release agent has the benefits of simple release, no pollution of the concrete surface, no corrosion of the template, easy to paint, low cost and etc. However, not all types of concrete release representatives with a selection of components made of templates are suitable for different supplies of the template and different development conditions and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.

As an essential construction auxiliary material, concrete release agent has the next characteristics:
Good isolation efficiency: concrete release agent can develop a dense isolation movie between the formwork and the concrete covering, effectively preventing the formwork from bonding with the concrete covering and facilitating the demolding.

Good lubrication overall performance: concrete release agent has good lubrication efficiency, which can reduce the chaffing between the formwork and concrete surface, reduce the resistance during pouring and enhance the construction productivity.

Good anti-adhesion efficiency: concrete release representatives can successfully stop the formwork from bonding with the concrete surface, avoiding the formwork from damaging the concrete area when dismantling the formwork.

Great waterproof overall performance: concrete release agent has good waterproof efficiency, which can effectively prevent moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and increasing the service life of the formwork.

Effortless to use and safe: concrete release agent is simple to use; you only need to apply a layer evenly on the formwork; at the same time, it is safe and environmentally friendly and will not pollute the human body and the environment.

When using a concrete release agent, the following steps should be followed:

Prepare tools: concrete release agent is usually sprayed or brushed for construction. You need to prepare construction tools such as a sprayer or brush.

Choose the right release agent: According to the different environments, choose the right concrete release agent, such as indoor use can choose a water-based concrete release agent, and outdoor use can choose an oil-based concrete release agent.

Apply the release agent: Pour the appropriate amount of release agent into the sprayer or container, and then evenly spray or brush on the formwork to ensure that each part is coated in place.

Air drying: After application, wait for a period of time to allow the release agent to dry naturally. Generally, it takes 10-20 minutes, depending on the environment.

Pouring concrete: After the release agent is completely air-dried, the concrete can be poured. During the pouring process, care should be taken to avoid air bubbles or voids between the formwork and the concrete surface.

Demolding: Demolding can be carried out after the concrete reaches the strength of demolding. When dismantling the formwork, the connectors at the edge of the formwork should be dismantled first, and then the surface of the formwork should be knocked gently to separate the formwork from the concrete area gradually. In case of tight bonding between the formwork and the concrete area, tools can be used appropriately to assist in the dismantling.

Clean up the template: after taking apart the template, the template should be cleaned up to remove the residual concrete and mould release agent. After cleaning, it can be used for the next time.

Application areas of concrete release agent:

Concrete release agent is widely used in all kinds of development projects, mainly including the following aspects:

Reinforced concrete structure: In the development of a reinforced concrete structure, concrete release agents can be used for formwork isolation, stopping formwork from bonding with concrete and improving construction efficiency and quality.

Road construction: in road construction, the concrete release agent can be used to isolate the bond layer between the road formwork and concrete surface, to avoid road bubbles, hollow drums and other problems.

Bridge project: In a bridge project, a concrete release agent can be used to isolate the bond layer between the bridge formwork and the concrete covering and improve the construction quality of the bridge pier and abutment.

Tunnelling project: In the tunnelling project, a concrete release agent can be used to isolate the bond layer between tunnel formwork and shotcrete surface to improve the quality and safety of tunnel construction.

Nuclear power project: In nuclear power project, a concrete release agent can be used to isolate the bond layer between the shell of nuclear power equipment and internal components to ensure the safety and stability of the equipment.

Other fields: concrete release agents can also be widely used in water conservancy projects, wharf projects, airport projects and other fields to provide effective formwork isolation protection measures for various construction projects.

In conclusion, concrete release agent, as an essential construction auxiliary material, plays an indispensable role in modern construction projects. By choosing the right kind, the correct use method and a reasonable application field, can effectively improve the construction efficiency and quality of the development project and provide a strong guarantee for the development of the construction industry.
