What is actually a concrete release agent?

A concrete release agent is a compound applied to the construction template before the concrete is added in order that the design doesn’t stick to to the concrete surface right after putting, isn’t easy to take apart the form or influences the end of the concrete surface. Its primary role in the design and the concrete covering to create a film that will be separated from the two is additionally called an remoteness agent.

A water-based release agent is definitely an important auxiliary in the release agent and can alter the water-based release agent stream and levelling; its principal attribute is actually stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based cast release agent is utilized in moulds and goods functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing cast goods are not just in order to let the mould release to boost productivity and lengthen the life of the form utilize. And can make the product thoroughly clean, size qualified, and decrease the creation of scrap, that is an important supplementary essential to forms and products – concrete release agent.

Concrete release agent plays an crucial role inside modern building building; its primary role is to develop a layer of separation movie between the template and the concrete area to ensure that the template does not adhere to the concrete surface to ensure that it is simpler to dismantle the mould after flowing and to maintain the end of the concrete area. Here, we will unveil the types, features, usage and application of concrete release agent at length.

Types of concrete release agent

Concrete release representatives can be divided into many types in accordance with different category techniques, and the typical category methods are as follows:

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

Features of Concrete release agent

A concrete release agent is also called a concrete isolation agent or mould release lubricant. It is really a kind of material coated on the inner wall of the formwork to play the role of lubricating and remoteness in order that the concrete could be easily detached from the formwork when taking apart the formwork, and the shape of the concrete could be kept intact and undamaged. Compared with the traditional release substance motor oil or waste motor oil, the release agent has the advantages of easy release, no pollution of the concrete area, no corrosion of the template, effortless to paint, low value and so on. However, not all kinds of concrete release agents with a array of materials made of templates are suitable for different supplies of the template and different construction circumstances and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.

As an crucial construction auxiliary material, concrete release agent has the following qualities:
Good isolation overall performance: concrete release agent can form a dense remoteness motion picture between the formwork and the concrete surface, successfully stopping the formwork from bonding with the concrete surface and facilitating the removing.

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

Good anti-adhesion efficiency: concrete release agents can efficiently avoid the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete surface when dismantling the formwork.

Excellent waterproof performance: concrete release agent has good waterproof overall performance, which can successfully prevent moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and improving 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 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 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 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 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 construction 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, preventing 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 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 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 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 essential construction auxiliary material, plays an indispensable role in modern construction projects. By choosing the right sort, 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 advancement of the building industry.
