What is a concrete release agent?

A concrete release agent is definitely a compound put on the building template before the concrete is put so the design does not stick to to the concrete covering right after pouring, isn’t easy to take down the form or influences the complete of the concrete surface. Its main role inside the template and the concrete surface to form a movie that will probably be separated from the two is additionally called an isolation agent.

A water-based release agent is an crucial supplementary within the release agent and can alter the water-based release agent stream and levelling; its primary attribute is stability to microorganisms and enzymes, which can decrease the expense of raw materials. A water-based mould release agent is used in moulds and products functional processing supplements; in the rubber, plastic, and Jinsu processing market, manufacturing form items are not only in order to let the mould release to enhance productivity and extend the life of the form use. And can make the item clear, size qualified, and lower the technology of scrap, that is an crucial additional vital to forms and items – concrete release agent.

Concrete release agent plays an important role in modern building construction; its main role would be to create a layer of remoteness movie between the template and the concrete area to ensure that the design doesn’t stick to the concrete covering in order that it is much easier to take down the form right after flowing and to maintain the end of the concrete covering. Here, we will unveil the types, characteristics, usage and application of concrete release agent in detail.

Sorts of concrete release agent

Concrete release representatives can be divided into many sorts in accordance with different category strategies, and the typical grouping techniques are the subsequent:

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

Qualities of Concrete release agent

A concrete release agent is also called a concrete isolation agent or mould release lubricant. It is really a kind of substance coated on the inner wall of the formwork to play the part of lubricating and isolation so that the concrete can be easily detached from the formwork when dismantling the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the standard release material motor oil or waste motor oil, the release agent has the positive aspects of easy release, no pollution of the concrete surface, no corrosion of the template, easy to paint, low cost and etc. However, not all kinds of concrete release representatives with a array of materials made of templates are suitable for different materials of the template and different construction problems and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.

As an crucial construction auxiliary material, concrete release agent has the following characteristics:
Good isolation overall performance: concrete release agent can form a dense remoteness motion picture between the formwork and the concrete covering, effectively preventing the formwork from bonding with the concrete area and facilitating the removing.

Excellent lubrication efficiency: concrete release agent has good lubrication overall performance, which can reduce the friction between the formwork and concrete covering, decrease the resistance during pouring and boost the construction productivity.

Excellent anti-adhesion efficiency: concrete release brokers can efficiently stop the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete covering when taking down the formwork.

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

Simple 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 petroleum-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 area of the formwork should be knocked gently to separate the formwork from the concrete surface 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 down 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 representatives can be used for formwork isolation, avoiding formwork from bonding with concrete and increasing 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 area and boost 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 brokers 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 development projects.

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