What is actually a concrete release agent?

A concrete release agent is a substance placed on the development template before the concrete is added so that the template does not stick to to the concrete area after flowing, is not effortless to take down the cast or affects the finish of the concrete surface. Its principal role in the template and the concrete surface to form a movie that will be separated from the two is also called an remoteness agent.

A water-based release agent is surely an important auxiliary in the release agent and can change the water-based release agent circulation and levelling; its principal feature is stability to microorganisms and enzymes, which can decrease the price of raw materials. A water-based mould release agent is used in forms and goods functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing form goods are not only to be able to let the form release to enhance productivity and extend the life of the form utilize. And can make the merchandise clean, size qualified, and reduce the technology of scrap, which is an crucial additional essential to moulds and goods – concrete additive.

Concrete release agent plays an important role within modern building building; its primary role is always to form a layer of remoteness film between the template and the concrete covering in order that the design will not adhere to the concrete area in order that it is much easier to dismantle the cast after pouring and to maintain the finish of the concrete covering. Here, we will introduce the sorts, characteristics, utilization and use of concrete release agent in more detail.

Types of concrete release agent

Concrete release representatives can be divided into many sorts in accordance with different classification techniques, and the typical classification techniques are the following:

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

Qualities of Concrete release agent

A concrete release agent can also be known as a concrete isolation agent or mould release lubricant. It is a kind of material coated on the inner wall of the formwork to play the role of lubrication and remoteness so that the concrete can be smoothly detached from the formwork when taking apart the formwork, and the condition of the concrete can be kept intact and undamaged. Compared with the conventional release material 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 kinds of concrete release agents with a variety of materials made of templates are suitable for different supplies of the template and different development circumstances 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 subsequent features:
Good remoteness efficiency: concrete release agent can develop a dense isolation movie between the formwork and the concrete area, efficiently avoiding the formwork from bonding with the concrete covering and facilitating the removing.

Good lubrication performance: concrete release agent has good lubrication overall performance, which can reduce the friction between the formwork and concrete covering, decrease the resistance during pouring and enhance the construction efficiency.

Great anti-adhesion efficiency: concrete release representatives can efficiently stop the formwork from bonding with the concrete surface, avoiding the formwork from damaging the concrete covering when taking apart the formwork.

Good waterproof overall performance: concrete release agent has good waterproof performance, which can efficiently stop moisture from penetrating between the formwork and concrete, avoiding 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 area.

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 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 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 development of a reinforced concrete structure, concrete release agents 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 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 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 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 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 building 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 building project and provide a strong guarantee for the advancement of the construction industry.
