What is actually a concrete release agent?

A concrete release agent is a material applied to the development template before the concrete is put so that the template doesn’t stick to to the concrete surface after pouring, isn’t easy to take apart the form or affects the end of the concrete area. Its primary role inside the design and the concrete surface to form a motion picture that will be separated from the two can also be known as an isolation agent.

A water-based release agent is surely an essential supplementary in the release agent and can modify the water-based release agent circulation and levelling; its primary feature is actually stability to microorganisms and enzymes, which can reduce the expense of raw materials. A water-based cast release agent can be used in forms and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing industry, manufacturing form items are not just so as to let the form release to boost productivity and extend the life of the mould make use of. And can make the merchandise thoroughly clean, size qualified, and lower the generation of scrap, which is an essential additive essential to forms and products – Water-based Concrete Release Agent.

Concrete release agent plays an important role inside modern building development; its principal role would be to form a layer of remoteness film between the template and the concrete covering in order that the template will not adhere to the concrete area in order that it is much easier to take down the mould right after flowing and to maintain the end of the concrete surface. Here, we will introduce the sorts, features, usage and use of concrete release agent in more detail.

Types of concrete release agent

Concrete release agents can be divided into many kinds in accordance with different category methods, and the common 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 so on.
• According to the composition: it can be divided into water-based concrete release brokers, petroleum-based concrete release brokers, silicone oil concrete release agents, etc.
• According to the use effect: it can be divided into ordinary concrete release brokers, simple to remove concrete release representatives, high-gloss concrete release representatives and so on.

Characteristics of Concrete release agent

A concrete release agent is additionally called a concrete separation agent or mould release lubricant. It is a sort of substance coated on the inner wall of the formwork to play the function of lubrication and isolation in order that the concrete may be smoothly detached from the formwork when taking down the formwork, and the form of the concrete could be kept intact and undamaged. Compared with the conventional release substance motor oil or waste motor oil, the release agent has the benefits of easy release, no pollution of the concrete covering, no corrosion of the template, easy to paint, low cost and etc. However, not all kinds of concrete release brokers with a selection of components made of templates are suitable for different components of the template and different development circumstances and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.

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

Excellent lubrication performance: concrete release agent has good lubricating efficiency, which can lower the friction between the formwork and concrete surface, lower the resistance during pouring and boost the construction productivity.

Good anti-adhesion performance: concrete release representatives can successfully stop the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete area when taking down the formwork.

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

Easy 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 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 taking apart the formwork, the connectors at the edge of the formwork should be dismantled first, and then the covering 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 dismantling.

Clean up the template: after taking apart 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 building 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 covering 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 improve 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 brokers 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 building projects. By choosing the right sort, 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 advancement of the development industry.
