What exactly is a concrete release agent?

A concrete release agent is definitely a substance placed on the development template just before the concrete is put in order that the design does not stick to to the concrete area right after flowing, is not simple to take apart the form or impacts the finish of the concrete area. Its principal role inside the template and the concrete covering to form a motion picture that is going to be separated from the two can also be called an isolation agent.

A water-based release agent is surely an essential ancillary in the release agent and can modify the water-based release agent circulation and levelling; its principal attribute is definitely stability to microorganisms and enzymes, which can decrease the price of raw materials. A water-based form release agent is used in forms and products functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing cast items aren’t just so as to let the cast release to improve productivity and lengthen the life of the mould use. And can make the product clear, size qualified, and lower the creation of scrap, which can be an crucial supplementary vital to casts and products – concrete additive.

Concrete release agent plays an important role within modern building building; its principal role would be to create a layer of isolation movie between the design and the concrete surface in order that the template will not stick to the concrete covering in order that it is easier to take down the form right after pouring and to maintain the finish of the concrete surface. Here, we will unveil the sorts, features, usage and application of concrete release agent in detail.

Types of concrete release agent

Concrete release brokers can be divided into several types in accordance with different classification techniques, and the frequent category 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 formula of: it can be divided into water-based concrete release representatives, oil-based concrete release brokers, silicone oil concrete release representatives, 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 remoteness agent or mould release lubricant. It is actually a sort of material coated on the inner wall of the formwork to play the function of lubrication and isolation to ensure that the concrete can be easily detached from the formwork when dismantling the formwork, and the shape of the concrete may be kept intact and undamaged. Compared with the traditional release materials motor oil or waste motor oil, the release agent has the benefits of simple release, no pollution of the concrete covering, no corrosion of the template, easy to paint, low cost and so on. However, not all kinds of concrete release agents with a selection of components made of templates are suitable for different supplies of the template and different building 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 qualities:
Good separation performance: concrete release agent can develop a dense isolation film between the formwork and the concrete covering, efficiently stopping the formwork from bonding with the concrete surface and facilitating the demolding.

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

Excellent anti-adhesion efficiency: concrete release representatives can successfully prevent the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete area when taking down the formwork.

Great waterproof performance: concrete release agent has good waterproof efficiency, which can effectively stop moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and improving 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 covering.

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 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 covering, tools can be used appropriately to assist in the taking down.

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, avoiding 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 covering, 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 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 boost 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 representatives 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 kind, 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 construction industry.
