What is actually a concrete release agent?

A concrete release agent is a compound placed on the development design just before the concrete is added in order that the template does not stick to to the concrete surface right after putting, isn’t easy to take down the form or influences the end of the concrete surface. Its main role inside the template and the concrete surface to develop a film that will probably be separated from the two can also be called an separation agent.

A water-based release agent is an crucial supplementary within the release agent and can change the water-based release agent flow and levelling; its principal characteristic is definitely stability to microorganisms and enzymes, which can lower the cost of raw materials. A water-based form release agent is used in moulds and items functional processing supplements; in the rubber, plastic, and Jinsu processing market, manufacturing form goods are not only so as to let the mould release to improve productivity and prolong the life of the form make use of. And can make the merchandise thoroughly clean, size qualified, and lower the technology of scrap, which is an crucial additive important to casts and products – concrete release agent.

Concrete release agent plays an important role in modern building development; its primary role is always to develop a layer of separation motion picture between the template and the concrete covering to ensure that the design will not stick to the concrete area to ensure that it is easier to take apart the cast following putting and to maintain the complete of the concrete area. Here, we will introduce the sorts, qualities, use and program of concrete release agent in more detail.

Kinds of concrete release agent

Concrete release brokers can be divided into numerous types in accordance with different classification techniques, and the frequent grouping strategies are the following:

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

Characteristics of Concrete release agent

A concrete release agent is also known as a concrete remoteness agent or mould release lubricant. It is really a type of compound coated on the inner wall of the formwork to play the part of lubrication and remoteness in order that the concrete could be effortlessly detached from the formwork when dismantling the formwork, and the form of the concrete can be kept intact and undamaged. Compared with the standard release materials motor oil or waste motor oil, the release agent has the benefits of effortless release, no pollution of the concrete area, no corrosion of the template, simple to paint, low cost and etc. However, not all kinds of concrete release brokers with a variety of components made of templates are suitable for different supplies of the template and different development conditions and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.

As an crucial construction auxiliary material, concrete release agent has the next qualities:
Good remoteness performance: concrete release agent can form a dense remoteness film between the formwork and the concrete surface, effectively avoiding the formwork from bonding with the concrete surface and facilitating the removing.

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

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

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

Effortless 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 surface gradually. In case of tight bonding between the formwork and the concrete area, tools can be used appropriately to assist in the dismantling.

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 building projects, mainly including the following aspects:

Reinforced concrete structure: In the building of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, preventing formwork from bonding with concrete and increasing 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 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 development 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 improve the construction efficiency and quality of the building project and provide a strong guarantee for the growth of the development industry.
