What is a concrete release agent?

A concrete release agent is actually a compound put on the construction template before the concrete is put in order that the template does not adhere to the concrete area after putting, isn’t easy to take down the mould or influences the complete of the concrete surface. Its primary role in the template and the concrete surface to create a motion picture that will be separated from the two can also be known as an remoteness agent.

A water-based release agent is definitely an crucial ancillary in the release agent and can alter the water-based release agent stream and levelling; its principal attribute is stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based cast release agent is utilized in forms and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing cast goods are not just to be able to let the form release to boost productivity and lengthen the life of the mould use. And can make the product clear, size qualified, and reduce the technology of scrap, which can be an important supplementary important to moulds and items – concrete release agent.

Concrete release agent plays an crucial role inside modern building development; its primary role is to create a layer of isolation motion picture between the template and the concrete covering in order that the template doesn’t stick to the concrete covering in order that it is easier to take down the mould right after flowing and to maintain the finish of the concrete covering. Here, we will present the types, features, use and application of concrete release agent in more detail.

Kinds of concrete release agent

Concrete release brokers can be divided into many types based on different grouping strategies, and the frequent grouping techniques are the subsequent:

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

Qualities of Concrete release agent

A concrete release agent is also called a concrete remoteness agent or mould release lubricant. It is a sort of material coated on the inner wall of the formwork to play the part of lubrication and remoteness to ensure that the concrete could be effortlessly detached from the formwork when dismantling the formwork, and the shape of the concrete could be kept intact and undamaged. Compared with the conventional release materials 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 cost and so on. However, not all sorts of concrete release brokers with a selection of materials made of templates are suitable for different supplies of the template and different construction problems 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 qualities:
Good remoteness performance: concrete release agent can create a dense remoteness movie between the formwork and the concrete surface, successfully stopping the formwork from bonding with the concrete area and facilitating the demolding.

Excellent lubrication overall 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 boost the construction effectiveness.

Good anti-adhesion efficiency: concrete release representatives can successfully stop the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete covering when dismantling the formwork.

Great waterproof efficiency: concrete release agent has good waterproof efficiency, which can efficiently stop 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 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 covering.

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 area 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 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 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 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 enhance 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 brokers 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 important construction auxiliary material, plays an indispensable role in modern construction 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 growth of the construction industry.
