What exactly is a concrete release agent?

A concrete release agent is definitely a substance put on the development template prior to the concrete is poured in order that the design does not stick to the concrete covering following pouring, is not effortless to take down the form or affects the end of the concrete area. Its main role in the template and the concrete surface to develop a movie that will be separated from the two can also be referred to as an isolation agent.

A water-based release agent is surely an important ancillary in the release agent and can change the water-based release agent circulation and levelling; its principal characteristic is actually stability to microorganisms and enzymes, which can decrease the price of raw materials. A water-based cast release agent can be used in moulds and items functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing mould goods aren’t just in order to let the form release to enhance productivity and extend the life of the form make use of. And can make the item thoroughly clean, size qualified, and reduce the generation of scrap, that is an important supplementary vital to moulds and products – concrete release agent.

Concrete release agent plays an essential role within modern building development; its principal role is always to create a layer of remoteness movie between the template and the concrete surface in order that the template does not stick to the concrete area to ensure that it is much easier to take apart the cast following putting and to maintain the end of the concrete area. Here, we will unveil the types, features, usage and program of concrete release agent in more detail.

Kinds of concrete release agent

Concrete release representatives can be divided into numerous kinds in accordance with different classification strategies, and the common category methods 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 discharge agent for tunnels and so on.
• According to the composition of: it can be divided into water-based concrete release brokers, oil-based concrete release agents, silicone oil concrete release representatives, etc.
• According to the utilization effect: it can be divided into ordinary concrete release agents, simple to remove concrete release brokers, high-gloss concrete release agents and and so forth.

Qualities of Concrete release agent

A concrete release agent is additionally known as a concrete isolation agent or mould release lubricant. It is actually a sort of material coated on the inner wall of the formwork to play the function of lubricating and remoteness so that the concrete can be effortlessly detached from the formwork when dismantling the formwork, and the shape of the concrete can be kept intact and undamaged. Compared with the traditional release substance motor oil or waste motor oil, the release agent has the positive aspects of effortless release, no pollution of the concrete area, no corrosion of the template, easy to paint, low cost and and so forth. However, not all types of concrete release agents with a selection of materials made of templates are suitable for different supplies of the template and different development conditions and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.

As an crucial construction auxiliary material, concrete release agent has the subsequent qualities:
Good remoteness efficiency: concrete release agent can form a dense isolation film between the formwork and the concrete area, successfully preventing the formwork from bonding with the concrete surface and facilitating the demolding.

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

Excellent anti-adhesion overall performance: concrete release agents can effectively stop the formwork from bonding with the concrete area, preventing the formwork from damaging the concrete area when taking down the formwork.

Good waterproof efficiency: concrete release agent has good waterproof efficiency, which can successfully stop moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and enhancing 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 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 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 covering, tools can be used appropriately to assist in the taking apart.

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 development of a reinforced concrete structure, concrete release representatives 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 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 covering and boost 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 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 construction projects.

In conclusion, concrete release agent, as an crucial 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 improve the construction efficiency and quality of the construction project and provide a strong guarantee for the advancement of the building industry.
