What is actually a concrete release agent?

A concrete release agent is definitely a substance put on the development template prior to the concrete is poured in order that the template does not stick to to the concrete area right after pouring, isn’t easy to take apart the cast or affects the finish of the concrete area. Its main role in the template and the concrete covering to develop a motion picture that will be separated from the two can also be called an isolation agent.

A water-based release agent is definitely an important supplementary inside the release agent and can modify the water-based release agent circulation and levelling; its main attribute is actually stability to microorganisms and enzymes, which can lower the cost of raw materials. A water-based form release agent can be used in moulds and items functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing mould items aren’t just to be able to let the mould release to enhance productivity and prolong the life of the cast utilize. And can make the product clean, size qualified, and reduce the generation of scrap, which can be an crucial additional important to forms and products – concrete additive.

Concrete release agent plays an important role in modern building development; its principal role is always to form a layer of remoteness motion picture between the design and the concrete covering in order that the design will not adhere to the concrete area so that it is easier to take down the mould right after pouring and to maintain the complete of the concrete surface. Here, we will unveil the types, features, utilization and use of concrete release agent in more detail.

Sorts of concrete release agent

Concrete release representatives can be divided into numerous sorts according to different category strategies, and the typical classification methods are as follows:

• According to the the scope of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete discharge agent for tunnels and and so forth.
• 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 brokers, etc.
• According to the use effect: it can be divided into ordinary concrete release agents, simple to remove concrete release agents, high-gloss concrete release agents and and so forth.

Characteristics of Concrete release agent

A concrete release agent is additionally known as a concrete isolation agent or mould release lubricant. It is actually a sort of substance coated on the inner wall of the formwork to play the role of lubrication and isolation to ensure that the concrete can be smoothly detached from the formwork when dismantling the formwork, and the condition of the concrete may be kept intact and undamaged. Compared with the conventional release material 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, simple to paint, low value and so on. However, not all kinds of concrete release brokers with a array of materials made of templates are suitable for different supplies of the template and different building problems 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 following features:
Good remoteness overall performance: concrete release agent can create a dense isolation motion picture between the formwork and the concrete surface, successfully stopping the formwork from bonding with the concrete surface and facilitating the demolding.

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

Good anti-adhesion efficiency: concrete release brokers can efficiently stop the formwork from bonding with the concrete surface, preventing 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.

Simple 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 covering.

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 covering gradually. In case of tight bonding between the formwork and the concrete area, tools can be used appropriately to assist in the taking down.

Clean up the template: after dismantling 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 development of a reinforced concrete structure, concrete release representatives 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 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 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 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 development 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 construction project and provide a strong guarantee for the development of the construction industry.
