What is a concrete release agent?

A concrete release agent is a compound placed on the development design prior to the concrete is put in order that the template will not stick to to the concrete covering right after flowing, is just not simple to take down the mould or influences the end of the concrete area. Its main role in the template and the concrete area to develop a motion picture that will be separated from the two can also be known as an separation agent.

A water-based release agent is definitely an crucial ancillary within the release agent and can change the water-based release agent stream and levelling; its primary feature is actually stability to microorganisms and enzymes, which can decrease the cost of raw materials. A water-based cast release agent is utilized in forms and goods functional processing additives; in the rubber, plastic, and Jinsu processing business, manufacturing cast products are not only so as to let the mould release to boost productivity and prolong the life of the form make use of. And can make the merchandise thoroughly clean, size qualified, and reduce the technology of scrap, which can be an important additional important to moulds and goods – concrete release agent.

Concrete release agent plays an crucial role within modern building development; its main role is always to form a layer of separation motion picture between the template and the concrete surface so that the design will not adhere to the concrete area to ensure that it is easier to take apart the mould right after putting and to maintain the end of the concrete covering. Here, we will introduce the sorts, qualities, use and program of concrete release agent in detail.

Sorts of concrete release agent

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

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

Features of Concrete release agent

A concrete release agent is also known as a concrete remoteness agent or mould release lubricant. It is a kind of substance coated on the inner wall of the formwork to play the function of lubricating and separation in order that the concrete may be effortlessly detached from the formwork when taking apart the formwork, and the form of the concrete could be kept intact and undamaged. Compared with the conventional release substance motor oil or waste motor oil, the release agent has the advantages of simple release, no pollution of the concrete area, no corrosion of the template, effortless to paint, low value and so on. However, not all types of concrete release representatives with a variety of components made of templates are suitable for different components of the template and different development 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 features:
Good remoteness overall performance: concrete release agent can develop a dense isolation film between the formwork and the concrete covering, successfully stopping the formwork from bonding with the concrete area and facilitating the demolding.

Great lubrication performance: concrete release agent has good lubricating efficiency, which can decrease the friction between the formwork and concrete covering, decrease the resistance during pouring and improve the construction productivity.

Great anti-adhesion performance: concrete release brokers can efficiently stop the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete surface when taking down the formwork.

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

Effortless 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 taking down the formwork, the connectors at the edge of the formwork should be dismantled first, and then the covering 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 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 construction projects, mainly including the following aspects:

Reinforced concrete structure: In the development of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, preventing 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 covering, 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 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 representatives 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 kind, 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.
