What is a concrete release agent?

A concrete release agent is actually a compound put on the building template prior to the concrete is added so the template doesn’t stick to to the concrete surface after pouring, is not easy to dismantle the cast or affects the finish of the concrete surface. Its main role inside the design and the concrete surface to form a motion picture that will probably be separated from the two can also be called an isolation agent.

A water-based release agent is definitely an crucial auxiliary in the release agent and can change the water-based release agent circulation and levelling; its main feature is definitely stability to microorganisms and enzymes, which can decrease the price of raw materials. A water-based form release agent can be used in moulds and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing form items are not just so as to let the form release to improve productivity and extend the life of the cast make use of. And can make the merchandise clear, size qualified, and decrease the technology of scrap, which can be an crucial additional vital to forms and products – Water-based Concrete Release Agent.

Concrete release agent plays an crucial role inside modern building building; its primary role would be to create a layer of isolation motion picture between the template and the concrete area to ensure that the design does not stick to the concrete surface to ensure that it is much easier to take apart the cast following pouring and to maintain the complete of the concrete area. Here, we will unveil the types, qualities, use and use of concrete release agent at length.

Kinds of concrete release agent

Concrete release representatives can be divided into numerous types according to different classification strategies, and the frequent category strategies 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 release agent for tunnels and etc.
• According to the the composition of: it can be divided into water-based concrete release brokers, oil-based concrete release agents, silicone oil concrete release representatives, etc.
• According to the use effect: it can be divided into ordinary concrete release representatives, easy-to-remove concrete release brokers, high-gloss concrete release brokers and and so forth.

Characteristics of Concrete release agent

A concrete release agent is also called a concrete isolation agent or mould release lubricant. It is actually a type of substance coated on the inner wall of the formwork to play the role of lubrication and separation to ensure that the concrete can be easily detached from the formwork when dismantling the formwork, and the shape of the concrete could be kept intact and undamaged. Compared with the standard release substance motor oil or waste motor oil, the release agent has the positive aspects of easy release, no pollution of the concrete covering, no corrosion of the template, effortless to paint, low price and etc. However, not all sorts of concrete release brokers with a variety of materials made of templates are suitable for different materials 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 subsequent characteristics:
Good isolation performance: concrete release agent can form a dense separation film between the formwork and the concrete surface, efficiently preventing the formwork from bonding with the concrete covering and facilitating the removing.

Good lubrication efficiency: concrete release agent has good lubricating performance, which can lower the chaffing between the formwork and concrete surface, reduce the resistance during pouring and enhance the construction efficiency.

Good anti-adhesion efficiency: concrete release representatives can effectively stop the formwork from bonding with the concrete covering, preventing the formwork from damaging the concrete covering when taking apart the formwork.

Great waterproof overall performance: concrete release agent has good waterproof overall performance, which can effectively avoid 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.

Simple 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 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 down.

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 construction of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, stopping 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 area, 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 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 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 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 construction 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 boost the construction efficiency and quality of the construction project and provide a strong guarantee for the growth of the construction industry.
