What is actually a concrete release agent?

A concrete release agent is definitely a substance put on the construction design prior to the concrete is poured so the template does not stick to to the concrete covering following pouring, is not effortless to dismantle the cast or impacts the finish of the concrete area. Its principal role in the design and the concrete surface to create a motion picture that will be separated from the two is additionally called an separation agent.

A water-based release agent is an essential auxiliary inside the release agent and can modify the water-based release agent circulation and levelling; its primary attribute is actually stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based mould release agent is used in casts and items functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing form items aren’t just so as to let the mould release to enhance productivity and prolong the life of the form use. And can make the item thoroughly clean, size qualified, and reduce the technology of scrap, that is an crucial additional important to forms and items – concrete release agent.

Concrete release agent plays an essential role in modern building construction; its primary role is to form a layer of isolation motion picture between the template and the concrete covering to ensure that the design will not adhere to the concrete surface to ensure that it is much easier to take apart the mould following pouring and to maintain the finish of the concrete area. Here, we will unveil the types, qualities, utilization and application of concrete release agent in more detail.

Types of concrete release agent

Concrete release agents can be divided into several kinds in accordance with different category strategies, and the frequent category strategies are as follows:

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

Qualities of Concrete release agent

A concrete release agent is also referred to as a concrete remoteness agent or mould release lubricant. It is a type of compound coated on the inner wall of the formwork to play the part of lubricating and isolation so that the concrete can be effortlessly detached from the formwork when taking down the formwork, and the form of the concrete may 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 simple release, no pollution of the concrete covering, no corrosion of the template, easy to paint, low value and and so forth. However, not all sorts of concrete release representatives with a variety of materials made of templates are suitable for different components of the template and different building circumstances and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.

As an important construction auxiliary material, concrete release agent has the subsequent features:
Good separation performance: concrete release agent can create a dense separation motion picture between the formwork and the concrete area, effectively stopping the formwork from bonding with the concrete area and facilitating the removing.

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

Great anti-adhesion performance: concrete release representatives can successfully prevent the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete covering when taking down the formwork.

Great waterproof overall performance: concrete release agent has good waterproof performance, which can successfully stop moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and improving the service life of the formwork.

Simple 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 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 area 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 area, 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 construction 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 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 representatives 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 building projects. By choosing the right type, the correct use method and a reasonable application field, can effectively enhance the construction efficiency and quality of the building project and provide a strong guarantee for the growth of the development industry.
