What exactly is a concrete release agent?

A concrete release agent is a material applied to the building template prior to the concrete is poured so the design doesn’t stick to the concrete covering following flowing, is not easy to take down the cast or affects the finish of the concrete area. Its principal role in the template and the concrete surface to develop a film that will be separated from the two is additionally called an separation agent.

A water-based release agent is an important supplementary within the release agent and can modify the water-based release agent circulation and levelling; its main feature is stability to microorganisms and enzymes, which can decrease the expense of raw materials. A water-based form release agent is used in forms and items functional processing ingredients; in the rubber, plastic, and Jinsu processing market, manufacturing form items are not just to be able to let the form release to enhance productivity and lengthen the life of the cast make use of. And can make the product thoroughly clean, size qualified, and reduce the creation of scrap, that is an crucial additive essential to moulds and goods – Water-based Concrete Release Agent.

Concrete release agent plays an essential role within modern building building; its primary role would be to develop a layer of separation movie between the template and the concrete area to ensure that the template does not stick to to the concrete surface in order that it is simpler to take down the form after putting and to maintain the end of the concrete covering. Here, we will introduce the types, qualities, utilization and program of concrete release agent in detail.

Sorts of concrete release agent

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

• 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 so on.
• According to the the composition of: it can be divided into water-based concrete release representatives, petroleum-based concrete release agents, silicone oil concrete release brokers, etc.
• According to the effect of use: it can be divided into ordinary concrete release agents, simple to remove concrete release brokers, high-gloss concrete release brokers and so on.

Characteristics of Concrete release agent

A concrete release agent can also be called a concrete separation agent or mould release lubricant. It is a kind of compound coated on the inner wall of the formwork to play the role of lubrication and separation so that the concrete may be effortlessly detached from the formwork when taking down the formwork, and the form of the concrete could be kept intact and undamaged. Compared with the standard release materials motor oil or waste motor oil, the release agent has the advantages of easy release, no pollution of the concrete covering, no corrosion of the template, simple to paint, low cost and so on. However, not all sorts of concrete release brokers with a selection of materials made of templates are suitable for different supplies of the template and different development circumstances and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.

As an essential construction auxiliary material, concrete release agent has the next features:
Good isolation overall performance: concrete release agent can create a dense separation film between the formwork and the concrete surface, effectively avoiding the formwork from bonding with the concrete area and facilitating the removing.

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

Good anti-adhesion performance: concrete release representatives can successfully stop the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete covering when taking apart the formwork.

Good waterproof efficiency: concrete release agent has good waterproof performance, which can successfully stop 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 area.

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 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 construction 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, 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 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 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 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 sort, the correct use method and a reasonable application field, can effectively improve the construction efficiency and quality of the construction project and provide a strong guarantee for the advancement of the construction industry.
