What is a concrete release agent?

A concrete release agent is a material put on the building template before the concrete is put in order that the template will not adhere to the concrete covering right after putting, is not simple to dismantle the cast or impacts the complete of the concrete surface. Its primary role in the template and the concrete covering to form a film that is going to be separated from the two can also be referred to as an separation agent.

A water-based release agent is surely an important auxiliary in the release agent and can change the water-based release agent circulation and levelling; its principal attribute is definitely stability to microorganisms and enzymes, which can reduce the expense of raw materials. A water-based form release agent is utilized in casts and goods functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing form items aren’t just in order to let the cast release to enhance productivity and extend the life of the mould use. And can make the product clean, size qualified, and decrease the technology of scrap, which can be an crucial supplementary vital to forms and products – concrete additive.

Concrete release agent plays an important role within modern building building; its primary role is always to create a layer of separation motion picture between the template and the concrete covering in order that the template will not stick to to the concrete surface in order that it is simpler to take down the cast following flowing and to maintain the finish of the concrete covering. Here, we will introduce the types, features, usage and application of concrete release agent at length.

Types of concrete release agent

Concrete release representatives can be divided into many sorts based on different grouping techniques, and the typical classification techniques are the following:

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

Qualities of Concrete release agent

A concrete release agent can also be referred to as a concrete isolation agent or mould release lubricant. It is really a type of compound coated on the inner wall of the formwork to play the role of lubricating and remoteness to ensure that the concrete can be easily detached from the formwork when taking apart the formwork, and the condition of the concrete may be kept intact and undamaged. Compared with the standard release materials motor oil or waste motor oil, the release agent has the advantages of effortless release, no pollution of the concrete covering, no corrosion of the template, simple to paint, low cost and etc. However, not all sorts of concrete release agents with a selection of components made of templates are suitable for different materials of the template and different construction problems and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.

As an crucial construction auxiliary material, concrete release agent has the next characteristics:
Good isolation performance: concrete release agent can form a dense remoteness film between the formwork and the concrete surface, successfully preventing the formwork from bonding with the concrete surface and facilitating the removing.

Good lubrication efficiency: concrete release agent has good lubricating efficiency, which can decrease the chaffing between the formwork and concrete area, decrease the resistance during pouring and improve the construction effectiveness.

Great anti-adhesion overall performance: concrete release brokers can efficiently avoid the formwork from bonding with the concrete surface, avoiding the formwork from damaging the concrete covering when dismantling the formwork.

Good waterproof performance: concrete release agent has good waterproof efficiency, which can efficiently prevent moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and improving the service life of the formwork.

Effortless 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 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 surface 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 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 development projects, mainly including the following aspects:

Reinforced concrete structure: In the building of a reinforced concrete structure, concrete release agents can be used for formwork isolation, stopping formwork from bonding with concrete and improving 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 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 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 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 kind, 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 construction industry.
