What is a concrete release agent?

A concrete release agent is actually a material put on the building template just before the concrete is put so the template does not adhere to the concrete surface right after pouring, isn’t easy to take apart the form or affects the complete of the concrete area. Its main role within the design and the concrete area to create a movie that is going to be separated from the two can also be known as an isolation agent.

A water-based release agent is definitely an crucial auxiliary in the release agent and can modify the water-based release agent circulation and levelling; its principal attribute is definitely stability to microorganisms and enzymes, which can decrease the price of raw materials. A water-based mould release agent is used in forms and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing mould items are not only to be able to let the cast release to boost productivity and extend the life of the mould utilize. And can make the item clean, size qualified, and decrease the creation of scrap, that is an crucial additional essential to casts and products – concrete additive.

Concrete release agent plays an crucial role inside modern building construction; its principal role would be to develop a layer of isolation motion picture between the template and the concrete area to ensure that the design does not stick to the concrete area so that it is much easier to dismantle the form following flowing and to maintain the complete of the concrete surface. Here, we will present the types, qualities, use and program of concrete release agent at length.

Kinds of concrete release agent

Concrete release agents can be divided into several kinds based on different category methods, and the typical category methods are the subsequent:

• According to the scope of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete launch agent for tunnels and etc.
• According to the composition: it can be divided into water-based concrete release agents, oil-based concrete release brokers, silicone oil concrete release brokers, etc.
• According to the use effect: it can be divided into ordinary concrete release brokers, simple to remove concrete release brokers, high-gloss concrete release brokers and etc.

Characteristics of Concrete release agent

A concrete release agent is also called a concrete separation agent or mould release lubricant. It is a kind of material coated on the inner wall of the formwork to play the role of lubricating and remoteness to ensure that the concrete could be easily detached from the formwork when taking apart the formwork, and the form of the concrete can be kept intact and undamaged. Compared with the traditional release material motor oil or waste motor oil, the release agent has the positive aspects of effortless release, no pollution of the concrete surface, no corrosion of the template, easy to paint, low value and so on. However, not all kinds of concrete release brokers with a variety of materials made of templates are suitable for different materials of the template and different development circumstances 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 subsequent features:
Good isolation efficiency: concrete release agent can develop a dense isolation motion picture between the formwork and the concrete surface, efficiently avoiding the formwork from bonding with the concrete covering and facilitating the demolding.

Great lubrication performance: concrete release agent has good lubrication overall performance, which can decrease the chaffing between the formwork and concrete covering, lower the resistance during pouring and improve the construction effectiveness.

Excellent anti-adhesion performance: concrete release representatives can effectively prevent the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete surface when dismantling the formwork.

Excellent waterproof performance: concrete release agent has good waterproof efficiency, which can efficiently prevent 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 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 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 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 construction 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, 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 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 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 building projects.

In conclusion, concrete release agent, as an important construction auxiliary material, plays an indispensable role in modern building 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 development project and provide a strong guarantee for the growth of the construction industry.
