What exactly is a concrete release agent?

A concrete release agent is a substance placed on the development template before the concrete is put so the design does not adhere to the concrete covering after putting, is just not simple to take apart the cast or impacts the end of the concrete covering. Its principal role in the template and the concrete covering to develop a film that will be separated from the two can also be called an remoteness agent.

A water-based release agent is an crucial supplementary in the release agent and can alter the water-based release agent flow and levelling; its principal attribute is actually stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based mould release agent can be used in forms and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing form items aren’t just to be able to let the cast release to improve productivity and extend the life of the form use. And can make the item clean, size qualified, and reduce the technology of scrap, that is an important additional essential to moulds and items – Water-based Concrete Release Agent.

Concrete release agent plays an crucial role within modern building construction; its main role is always to create a layer of isolation motion picture between the template and the concrete area to ensure that the template doesn’t adhere to the concrete area in order that it is simpler to dismantle the form following pouring and to maintain the end of the concrete surface. Here, we will introduce the kinds, characteristics, usage and use of concrete release agent in more detail.

Kinds of concrete release agent

Concrete release brokers can be divided into numerous kinds according to different classification strategies, and the common classification methods are as follows:

• According to the scope of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete emission agent for tunnels and etc.
• According to the the composition of: it can be divided into water-based concrete release representatives, 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 agents, high-gloss concrete release representatives and etc.

Qualities of Concrete release agent

A concrete release agent is also called a concrete separation agent or mould release lubricant. It is actually a type of compound coated on the inner wall of the formwork to play the part of lubricating and isolation to ensure that the concrete could be smoothly detached from the formwork when taking down the formwork, and the condition of the concrete can be kept intact and undamaged. Compared with the conventional release material motor oil or waste motor oil, the release agent has the benefits of simple release, no pollution of the concrete covering, no corrosion of the template, simple to paint, low value and so on. However, not all types of concrete release brokers with a array of supplies made of templates are suitable for different materials of the template and different development problems 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 next qualities:
Good isolation performance: concrete release agent can develop a dense isolation movie between the formwork and the concrete area, efficiently stopping the formwork from bonding with the concrete area and facilitating the demolding.

Great lubrication performance: concrete release agent has good lubricating overall performance, which can lower the friction between the formwork and concrete surface, decrease the resistance during pouring and boost the construction effectiveness.

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

Great waterproof efficiency: concrete release agent has good waterproof performance, which can effectively prevent moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and increasing 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 covering.

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 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 covering, tools can be used appropriately to assist in the taking down.

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 development 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, stopping formwork from bonding with concrete and increasing 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 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 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 kind, 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.
