What is a concrete release agent?

A concrete release agent is actually a compound put on the building design before the concrete is poured so the template doesn’t stick to the concrete surface right after pouring, isn’t easy to take apart the mould or impacts the finish of the concrete area. Its primary role within the template and the concrete area to create a motion picture that is going to be separated from the two is also known as an remoteness agent.

A water-based release agent is surely an crucial supplementary inside the release agent and can alter the water-based release agent flow and levelling; its main feature is stability to microorganisms and enzymes, which can reduce the expense of raw materials. A water-based form release agent is utilized in forms and products functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing form products are not only to be able to let the mould release to improve productivity and prolong the life of the cast use. And can make the item clear, size qualified, and decrease the technology of scrap, that is an essential supplementary vital to casts and products – concrete additive.

Concrete release agent plays an important role inside modern building construction; its primary role would be to develop a layer of separation movie between the template and the concrete surface to ensure that the template doesn’t stick to to the concrete area in order that it is simpler to dismantle the mould following putting and to maintain the finish of the concrete covering. Here, we will unveil the types, characteristics, utilization and program of concrete release agent in detail.

Kinds of concrete release agent

Concrete release brokers can be divided into several kinds in accordance with different grouping strategies, and the typical classification techniques are the following:

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

Qualities of Concrete release agent

A concrete release agent is additionally known as a concrete separation agent or mould release lubricant. It is a type of substance coated on the inner wall of the formwork to play the part of lubrication and separation so that the concrete can be easily detached from the formwork when taking down the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the conventional release material motor oil or waste motor oil, the release agent has the benefits of easy release, no pollution of the concrete surface, no corrosion of the template, effortless to paint, low price and and so forth. However, not all types of concrete release agents with a selection of supplies made of templates are suitable for different materials of the template and different construction conditions 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 next characteristics:
Good remoteness performance: concrete release agent can create a dense remoteness motion picture between the formwork and the concrete area, successfully preventing the formwork from bonding with the concrete covering and facilitating the demolding.

Excellent lubrication efficiency: concrete release agent has good lubrication performance, which can decrease the chaffing between the formwork and concrete surface, decrease the resistance during pouring and improve the construction efficiency.

Good anti-adhesion efficiency: concrete release brokers can effectively avoid the formwork from bonding with the concrete covering, steering clear of the formwork from damaging the concrete area when taking apart the formwork.

Good waterproof efficiency: concrete release agent has good waterproof efficiency, which can effectively avoid moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and improving the service life of the formwork.

Easy 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 surface.

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

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 development of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, avoiding 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 essential construction auxiliary material, plays an indispensable role in modern development 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 building project and provide a strong guarantee for the advancement of the building industry.
