What is a concrete release agent?

A concrete release agent is a material placed on the construction template prior to the concrete is poured in order that the template will not stick to the concrete covering following putting, is just not effortless to take down the cast or influences the end of the concrete area. Its main role inside the template and the concrete surface to form a film that will probably be separated from the two can also be known as an isolation agent.

A water-based release agent is definitely an crucial ancillary within the release agent and can modify the water-based release agent circulation and levelling; its principal characteristic is actually stability to microorganisms and enzymes, which can lower the cost of raw materials. A water-based form release agent is used in forms and goods functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing form items are not only so as to let the cast release to boost productivity and lengthen the life of the mould utilize. And can make the item clear, size qualified, and reduce the technology of scrap, that is an important additive vital to moulds and items – concrete additive.

Concrete release agent plays an crucial role in modern building building; its principal role is to develop a layer of isolation movie between the template and the concrete area in order that the template will not stick to the concrete area in order that it is much easier to take down the mould after pouring and to maintain the complete of the concrete covering. Here, we will unveil the sorts, characteristics, use and use of concrete release agent in detail.

Types of concrete release agent

Concrete release agents can be divided into numerous kinds according to different classification strategies, and the typical grouping methods are as follows:

• According to the scope of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete emission agent for tunnels and so on.
• According to the the formula of: it can be divided into water-based concrete release brokers, oil-based concrete release agents, silicone oil concrete release brokers, etc.
• According to the utilization 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 can also be known 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 lubricating and separation in order that the concrete may be effortlessly detached from the formwork when taking down the formwork, and the shape of the concrete may be kept intact and undamaged. Compared with the conventional release materials motor oil or waste motor oil, the release agent has the positive aspects of simple release, no pollution of the concrete area, no corrosion of the template, easy to paint, low value and so on. However, not all kinds of concrete release brokers with a array of components made of templates are suitable for different materials of the template and different development problems and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.

As an essential construction auxiliary material, concrete release agent has the next characteristics:
Good separation efficiency: concrete release agent can create a dense remoteness film between the formwork and the concrete covering, effectively preventing the formwork from bonding with the concrete surface and facilitating the removing.

Good lubrication performance: concrete release agent has good lubrication efficiency, which can reduce the rubbing between the formwork and concrete surface, decrease the resistance during pouring and improve the construction efficiency.

Excellent anti-adhesion performance: concrete release agents can efficiently avoid the formwork from bonding with the concrete surface, steering clear of the formwork from damaging the concrete surface when taking apart the formwork.

Good waterproof overall performance: concrete release agent has good waterproof overall performance, which can successfully prevent moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and enhancing the service life of the formwork.

Effortless to use and safe: concrete release agent is effortless 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 taking down 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 surface, tools can be used appropriately to assist in the taking apart.

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 construction of a reinforced concrete structure, concrete release brokers can be used for formwork isolation, preventing formwork from bonding with concrete and enhancing 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 area, 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 surface 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 enhance 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 crucial construction auxiliary material, plays an indispensable role in modern development projects. By choosing the right type, the correct use method and a reasonable application field, can effectively boost the construction efficiency and quality of the building project and provide a strong guarantee for the development of the building industry.
