What is a concrete release agent?

A concrete release agent is a compound applied to the construction design before the concrete is put so that the design does not stick to to the concrete area after putting, is not simple to dismantle the form or influences the end of the concrete area. Its main role inside the design and the concrete area to form a movie that will probably be separated from the two is additionally referred to as an remoteness agent.

A water-based release agent is surely an essential supplementary within the release agent and can alter the water-based release agent circulation and levelling; its principal attribute is actually stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based form release agent can be used in moulds and goods functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing mould goods aren’t just in order to let the mould release to boost productivity and extend the life of the form make use of. And can make the item clean, size qualified, and decrease the creation of scrap, which can be an crucial supplementary vital to moulds and items – concrete additive.

Concrete release agent plays an essential role within modern building building; its main role is to create a layer of remoteness motion picture between the template and the concrete surface to ensure that the template does not stick to the concrete area in order that it is much easier to take apart the mould following flowing and to maintain the complete of the concrete covering. Here, we will present the sorts, features, usage and application of concrete release agent at length.

Sorts of concrete release agent

Concrete release agents can be divided into many sorts in accordance with different category methods, and the common 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 etc.
• 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 effect of use: it can be divided into ordinary concrete release agents, easy-to-remove concrete release representatives, high-gloss concrete release brokers and and so forth.

Characteristics of Concrete release agent

A concrete release agent can also be referred to as a concrete separation agent or mould release lubricant. It is a kind of compound coated on the inner wall of the formwork to play the role of lubricating and remoteness to ensure that the concrete could be easily detached from the formwork when taking down the formwork, and the form of the concrete could be kept intact and undamaged. Compared with the standard release materials motor oil or waste motor oil, the release agent has the benefits of easy release, no pollution of the concrete surface, no corrosion of the template, effortless to paint, low price and etc. However, not all types of concrete release representatives with a variety of supplies made of templates are suitable for different components of the template and different construction conditions and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.

As an important construction auxiliary material, concrete release agent has the following characteristics:
Good remoteness overall performance: concrete release agent can form a dense separation movie between the formwork and the concrete covering, successfully preventing the formwork from bonding with the concrete surface and facilitating the dismantling.

Good lubrication performance: concrete release agent has good lubricating overall performance, which can decrease the friction between the formwork and concrete area, reduce the resistance during pouring and improve the construction productivity.

Great anti-adhesion efficiency: concrete release agents can effectively stop the formwork from bonding with the concrete area, preventing the formwork from damaging the concrete covering when taking down 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, steering clear of deformation of the formwork by moisture and increasing the service life of the formwork.

Easy to use and safe: concrete release agent is effortless 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 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 surface 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 covering, 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 building 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, avoiding 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 surface and boost 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 enhance the construction efficiency and quality of the construction project and provide a strong guarantee for the growth of the construction industry.
