What is actually a concrete release agent?

A concrete release agent is actually a substance put on the development template before the concrete is put so that the template doesn’t stick to to the concrete covering right after flowing, is not effortless to take apart 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 is going to be separated from the two can also be known as an remoteness agent.

A water-based release agent is definitely an crucial auxiliary in the release agent and can alter the water-based release agent circulation and levelling; its primary attribute is definitely stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based cast release agent is utilized in forms and goods functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing mould goods are not only so as to let the cast release to boost productivity and lengthen the life of the mould use. And can make the product thoroughly clean, size qualified, and reduce the creation of scrap, that is an crucial additive important to moulds and items – Water-based Concrete Release Agent.

Concrete release agent plays an crucial role inside modern building construction; its primary role is always to create a layer of isolation motion picture between the design and the concrete surface so that the template will not adhere to the concrete area so that it is much easier to dismantle the mould right after pouring and to maintain the end of the concrete surface. Here, we will present the types, characteristics, utilization and use of concrete release agent at length.

Kinds of concrete release agent

Concrete release representatives can be divided into many types according to different classification methods, and the common grouping methods are the following:

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

Qualities of Concrete release agent

A concrete release agent can also be known as a concrete isolation agent or mould release lubricant. It is actually a kind of material coated on the inner wall of the formwork to play the function of lubrication and isolation so that the concrete could be easily detached from the formwork when taking down the formwork, and the shape of the concrete could be kept intact and undamaged. Compared with the standard release substance motor oil or waste motor oil, the release agent has the advantages of effortless release, no pollution of the concrete covering, no corrosion of the template, effortless to paint, low price and etc. However, not all sorts of concrete release representatives with a array of materials made of templates are suitable for different components 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 crucial construction auxiliary material, concrete release agent has the following features:
Good separation performance: concrete release agent can form a dense separation motion picture between the formwork and the concrete surface, efficiently stopping the formwork from bonding with the concrete area and facilitating the dismantling.

Good lubrication performance: concrete release agent has good lubrication efficiency, which can lower the chaffing between the formwork and concrete surface, reduce the resistance during pouring and improve the construction productivity.

Excellent anti-adhesion overall performance: concrete release brokers can successfully stop the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete surface when taking apart the formwork.

Good waterproof efficiency: concrete release agent has good waterproof overall performance, which can effectively stop moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and increasing the service life of the formwork.

Easy to use and safe: concrete release agent is easy 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 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 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 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 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 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 enhance 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 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 development projects. By choosing the right kind, 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 development of the development industry.
