What is actually a concrete release agent?

A concrete release agent is definitely a substance placed on the development design just before the concrete is put in order that the design doesn’t adhere to the concrete area right after flowing, is just not simple to take down the form or impacts the finish of the concrete surface. Its primary role within the design and the concrete surface to create a film that will probably be separated from the two can also be called an separation agent.

A water-based release agent is an important supplementary in the release agent and can modify the water-based release agent stream and levelling; its principal feature is definitely stability to microorganisms and enzymes, which can lower 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 business, manufacturing form items aren’t just to be able to let the cast release to boost productivity and prolong the life of the form utilize. And can make the item clear, size qualified, and reduce the technology of scrap, which is an crucial supplementary vital to forms and items – concrete additive.

Concrete release agent plays an essential role inside modern building construction; its principal role is always to develop a layer of remoteness motion picture between the design and the concrete surface to ensure that the template doesn’t adhere to the concrete surface to ensure that it is simpler to dismantle the form after flowing and to maintain the finish of the concrete area. Here, we will unveil the types, features, utilization and application of concrete release agent in more detail.

Kinds of concrete release agent

Concrete release agents can be divided into numerous types based on different category techniques, and the frequent grouping techniques are the following:

• 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 and so forth.
• According to the composition of: 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 effect of use: it can be divided into ordinary concrete release brokers, an easy task to remove concrete release brokers, high-gloss concrete release representatives and so on.

Characteristics of Concrete release agent

A concrete release agent is additionally called a concrete isolation agent or mould release lubricant. It is really a type of material coated on the inner wall of the formwork to play the function of lubricating and separation in order that the concrete can be easily detached from the formwork when dismantling the formwork, and the form of the concrete can be kept intact and undamaged. Compared with the standard release material motor oil or waste motor oil, the release agent has the benefits of effortless release, no pollution of the concrete area, no corrosion of the template, easy to paint, low value and so on. However, not all types of concrete release representatives with a array of materials made of templates are suitable for different materials of the template and different building 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 following qualities:
Good remoteness efficiency: concrete release agent can create a dense separation movie between the formwork and the concrete covering, successfully stopping the formwork from bonding with the concrete area and facilitating the demolding.

Great lubrication efficiency: concrete release agent has good lubricating efficiency, which can lower the rubbing between the formwork and concrete surface, reduce the resistance during pouring and boost the construction efficiency.

Good anti-adhesion performance: concrete release representatives can efficiently prevent the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete surface when taking down the formwork.

Excellent waterproof overall performance: concrete release agent has good waterproof overall performance, which can efficiently avoid 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 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 covering.

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

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 building of a reinforced concrete structure, concrete release representatives 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 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 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 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 building 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 enhance the construction efficiency and quality of the development project and provide a strong guarantee for the growth of the construction industry.
