What exactly is a concrete release agent?

A concrete release agent is definitely a substance applied to the building template just before the concrete is poured in order that the design doesn’t stick to to the concrete area right after putting, isn’t easy to dismantle the mould or influences the complete of the concrete surface. Its primary role inside the template and the concrete surface to form a film that will probably be separated from the two is additionally called an separation agent.

A water-based release agent is definitely an essential supplementary in the release agent and can change the water-based release agent circulation and levelling; its principal feature is stability to microorganisms and enzymes, which can decrease the expense of raw materials. A water-based mould release agent can be used in casts and products functional processing supplements; in the rubber, plastic, and Jinsu processing market, manufacturing cast products are not only in order to let the mould release to boost productivity and extend the life of the mould use. And can make the product clear, size qualified, and decrease the creation of scrap, which is an important additive important to forms and products – concrete additive.

Concrete release agent plays an crucial role within modern building construction; its primary role is always to develop a layer of isolation motion picture between the template and the concrete covering to ensure that the template does not stick to the concrete area in order that it is simpler to take apart the form following pouring and to maintain the finish of the concrete covering. Here, we will introduce the types, features, use and application of concrete release agent in more detail.

Sorts of concrete release agent

Concrete release agents can be divided into many types in accordance with different classification methods, and the frequent classification methods are the subsequent:

• According to the 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 and so forth.
• According to the the composition: it can be divided into water-based concrete release representatives, oil-based concrete release brokers, silicone oil concrete release representatives, etc.
• According to the use effect: it can be divided into ordinary concrete release representatives, an easy task to remove concrete release representatives, high-gloss concrete release brokers and and so forth.

Features of Concrete release agent

A concrete release agent can also be called a concrete remoteness agent or mould release lubricant. It is a type of material coated on the inner wall of the formwork to play the role of lubricating and isolation in order that the concrete can be effortlessly detached from the formwork when dismantling the formwork, and the shape 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 simple release, no pollution of the concrete area, no corrosion of the template, easy to paint, low cost and so on. However, not all types of concrete release brokers with a array of components made of templates are suitable for different components of the template and different construction circumstances and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.

As an important construction auxiliary material, concrete release agent has the following qualities:
Good isolation overall performance: concrete release agent can develop a dense remoteness motion picture between the formwork and the concrete area, efficiently avoiding the formwork from bonding with the concrete surface and facilitating the demolding.

Good lubrication performance: concrete release agent has good lubricating overall performance, which can reduce the chaffing between the formwork and concrete surface, lower the resistance during pouring and boost the construction efficiency.

Good anti-adhesion performance: concrete release representatives can effectively prevent the formwork from bonding with the concrete surface, avoiding the formwork from damaging the concrete covering when taking down the formwork.

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

Effortless 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 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 covering 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 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 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, preventing 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 surface, 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 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 building 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 building project and provide a strong guarantee for the development of the development industry.
