What exactly is a concrete release agent?

A concrete release agent is definitely a material applied to the construction template just before the concrete is poured so the design doesn’t adhere to the concrete surface following pouring, is not easy to take apart the cast or impacts the end of the concrete area. Its primary role in the design and the concrete surface to create a motion picture that will probably be separated from the two can also be referred to as an isolation agent.

A water-based release agent is an important auxiliary within the release agent and can modify the water-based release agent stream and levelling; its main feature is actually stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based cast release agent is used in casts and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing cast products are not only in order to let the form release to boost productivity and extend the life of the cast utilize. And can make the item thoroughly clean, size qualified, and decrease the creation of scrap, that is an crucial additive vital to moulds and items – concrete release agent.

Concrete release agent plays an essential role in modern building development; its principal role would be to form a layer of isolation film between the design and the concrete area to ensure that the template will not adhere to the concrete area to ensure that it is simpler to take apart the form after flowing and to maintain the complete of the concrete covering. Here, we will unveil the sorts, characteristics, usage and application of concrete release agent at length.

Types of concrete release agent

Concrete release representatives can be divided into many kinds in accordance with different grouping methods, and the common grouping strategies are the subsequent:

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

Characteristics of Concrete release agent

A concrete release agent is also called a concrete isolation agent or mould release lubricant. It is actually a type of substance coated on the inner wall of the formwork to play the role of lubricating and isolation so that the concrete could be smoothly detached from the formwork when dismantling the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the traditional release materials motor oil or waste motor oil, the release agent has the positive aspects of easy release, no pollution of the concrete covering, no corrosion of the template, easy to paint, low value and etc. However, not all kinds of concrete release agents with a array of components made of templates are suitable for different supplies of the template and different development circumstances and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.

As an crucial construction auxiliary material, concrete release agent has the subsequent features:
Good separation overall performance: concrete release agent can create a dense isolation movie between the formwork and the concrete covering, efficiently avoiding the formwork from bonding with the concrete area and facilitating the removing.

Good lubrication efficiency: concrete release agent has good lubricating efficiency, which can decrease the rubbing between the formwork and concrete area, reduce the resistance during pouring and improve the construction effectiveness.

Great anti-adhesion efficiency: concrete release representatives can effectively avoid the formwork from bonding with the concrete surface, steering clear of the formwork from damaging the concrete covering when taking down the formwork.

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

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

Clean up the template: after dismantling 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 construction of a reinforced concrete structure, concrete release representatives 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 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 boost 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 construction projects.

In conclusion, concrete release agent, as an essential construction auxiliary material, plays an indispensable role in modern construction projects. By choosing the right kind, 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 advancement of the construction industry.
