What is a concrete release agent?

A concrete release agent is definitely a material applied to the development template just before the concrete is put so the design doesn’t stick to the concrete area right after putting, is not easy to take down the mould or influences the finish of the concrete surface. Its principal role inside the template and the concrete surface to form a movie that is going to be separated from the two can also be called an remoteness agent.

A water-based release agent is an important ancillary within the release agent and can alter the water-based release agent circulation and levelling; its primary characteristic is definitely stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based cast release agent is used in casts and products functional processing ingredients; in the rubber, plastic, and Jinsu processing industry, manufacturing mould items are not just in order to let the cast release to boost productivity and lengthen the life of the form utilize. And can make the product clear, size qualified, and reduce the creation of scrap, that is an important supplementary essential to casts and items – concrete additive.

Concrete release agent plays an important role within modern building building; its principal role is always to develop a layer of separation movie between the design and the concrete area to ensure that the template does not stick to the concrete surface so that it is much easier to dismantle the mould following pouring and to maintain the finish of the concrete surface. Here, we will present the types, characteristics, usage and use of concrete release agent at length.

Kinds of concrete release agent

Concrete release brokers can be divided into numerous types in accordance with different classification methods, and the common category methods are as follows:

• According to the the opportunity 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 brokers, petroleum-based concrete release agents, silicone oil concrete release representatives, etc.
• According to the the use effect: it can be divided into ordinary concrete release agents, an easy task to remove concrete release brokers, high-gloss concrete release representatives and and so forth.

Characteristics of Concrete release agent

A concrete release agent is also called a concrete remoteness agent or mould release lubricant. It is actually a kind of material coated on the inner wall of the formwork to play the part of lubrication and separation so that the concrete can be smoothly detached from the formwork when dismantling the formwork, and the form of the concrete can be kept intact and undamaged. Compared with the conventional release substance motor oil or waste motor oil, the release agent has the benefits of simple release, no pollution of the concrete surface, no corrosion of the template, easy to paint, low value and so on. However, not all kinds of concrete release agents with a selection of materials made of templates are suitable for different materials of the template and different construction conditions 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 subsequent characteristics:
Good separation efficiency: concrete release agent can create a dense separation motion picture between the formwork and the concrete area, effectively avoiding the formwork from bonding with the concrete surface and facilitating the removing.

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

Excellent anti-adhesion performance: concrete release brokers can successfully prevent the formwork from bonding with the concrete area, preventing the formwork from damaging the concrete area when dismantling the formwork.

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

Easy 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 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 area.

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 covering gradually. In case of tight bonding between the formwork and the concrete covering, 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 construction projects, mainly including the following aspects:

Reinforced concrete structure: In the construction 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 surface 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 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 construction projects.

In conclusion, concrete release agent, as an essential 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 development project and provide a strong guarantee for the growth of the development industry.
