What is actually a concrete release agent?

A concrete release agent is actually a substance applied to the building template before the concrete is poured so the template does not stick to the concrete surface after putting, is not effortless to take apart the form or impacts the end of the concrete area. Its main role within the design and the concrete surface to create a motion picture that will be separated from the two is additionally called an isolation agent.

A water-based release agent is definitely an essential auxiliary within the release agent and can modify the water-based release agent flow and levelling; its main characteristic is actually stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based form release agent can be used in casts and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing market, manufacturing form goods are not only in order to let the mould release to boost productivity and lengthen the life of the form utilize. And can make the item clear, size qualified, and decrease the technology of scrap, that is an crucial additional vital to moulds and products – concrete additive.

Concrete release agent plays an crucial role within modern building development; its main role is always to form a layer of separation movie between the template and the concrete area to ensure that the template will not stick to the concrete covering in order that it is easier to take apart the mould right after flowing and to maintain the complete of the concrete covering. Here, we will introduce the kinds, features, usage and program of concrete release agent in more detail.

Kinds of concrete release agent

Concrete release representatives can be divided into several kinds according to different category techniques, and the common classification methods are the following:

• According to the opportunity of use: it can be divided into concrete release agent for construction, 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 representatives, oil-based concrete release brokers, silicone oil concrete release brokers, etc.
• According to the the effect of use: it can be divided into ordinary concrete release brokers, simple to remove concrete release brokers, high-gloss concrete release agents and and so forth.

Characteristics of Concrete release agent

A concrete release agent is also known as a concrete remoteness agent or mould release lubricant. It is really a kind of material coated on the inner wall of the formwork to play the function of lubrication and remoteness so that the concrete may be easily detached from the formwork when taking down the formwork, and the shape 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 easy release, no pollution of the concrete covering, no corrosion of the template, simple to paint, low price and etc. However, not all types of concrete release agents with a variety of supplies made of templates are suitable for different components 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 important construction auxiliary material, concrete release agent has the following characteristics:
Good isolation efficiency: concrete release agent can develop a dense separation motion picture between the formwork and the concrete covering, successfully stopping the formwork from bonding with the concrete surface and facilitating the demolding.

Great lubrication overall performance: concrete release agent has good lubricating overall performance, which can decrease the rubbing between the formwork and concrete surface, lower the resistance during pouring and improve the construction productivity.

Excellent anti-adhesion efficiency: concrete release representatives can effectively prevent the formwork from bonding with the concrete covering, preventing the formwork from damaging the concrete area when taking apart 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, preventing deformation of the formwork by moisture and improving the service life of the formwork.

Simple 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 surface gradually. In case of tight bonding between the formwork and the concrete area, tools can be used appropriately to assist in the taking apart.

Clean up the template: after dismantling 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 building projects, mainly including the following aspects:

Reinforced concrete structure: In the building of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, stopping 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 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 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 important 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 improve the construction efficiency and quality of the construction project and provide a strong guarantee for the advancement of the development industry.
