What exactly is a concrete release agent?

A concrete release agent is definitely a substance applied to the development template just before the concrete is added so the template does not stick to to the concrete covering following pouring, isn’t simple to take down the mould or influences the finish of the concrete area. Its primary role within the design and the concrete covering to form a motion picture that will be separated from the two is additionally called an isolation agent.

A water-based release agent is an crucial ancillary inside the release agent and can alter the water-based release agent flow and levelling; its main characteristic is stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based form release agent can be used in forms and products functional processing supplements; in the rubber, plastic, and Jinsu processing market, manufacturing cast goods aren’t just in order to let the form release to boost productivity and extend the life of the cast utilize. And can make the merchandise clean, size qualified, and lower the generation of scrap, which is an important supplementary vital to moulds and items – concrete additive.

Concrete release agent plays an important role in modern building construction; its main role is to develop a layer of separation motion picture between the template and the concrete covering in order that the template does not adhere to the concrete area so that it is easier to take apart the form right after putting and to maintain the complete of the concrete surface. Here, we will introduce the types, characteristics, use and application of concrete release agent in more detail.

Sorts of concrete release agent

Concrete release agents can be divided into many types based on different classification techniques, and the frequent category strategies are the subsequent:

• 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 and so forth.
• According to 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 brokers, high-gloss concrete release brokers and etc.

Features of Concrete release agent

A concrete release agent is also known as a concrete remoteness agent or mould release lubricant. It is really a type of material coated on the inner wall of the formwork to play the part of lubricating and remoteness to ensure that the concrete may be easily detached from the formwork when dismantling the formwork, and the form 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 simple release, no pollution of the concrete covering, no corrosion of the template, effortless to paint, low cost and etc. However, not all sorts of concrete release agents with a variety of materials 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 appropriate release agent in order to receive good results.

As an important construction auxiliary material, concrete release agent has the subsequent characteristics:
Good isolation overall performance: concrete release agent can create a dense isolation movie between the formwork and the concrete surface, successfully avoiding the formwork from bonding with the concrete surface and facilitating the removing.

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

Excellent anti-adhesion efficiency: concrete release agents can successfully avoid the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete covering when taking down the formwork.

Great waterproof 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 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 area.

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

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 development projects, mainly including the following aspects:

Reinforced concrete structure: In the building 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 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 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 building projects.

In conclusion, concrete release agent, as an crucial construction auxiliary material, plays an indispensable role in modern development 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 development project and provide a strong guarantee for the growth of the development industry.
