What is actually a concrete release agent?

A concrete release agent is actually a compound placed on the building design just before the concrete is added in order that the template will not adhere to the concrete area after putting, isn’t simple to take apart the form or impacts the finish of the concrete area. Its primary role inside the template and the concrete surface to create a motion picture that will probably be separated from the two is additionally referred to as an separation agent.

A water-based release agent is an important supplementary inside the release agent and can alter the water-based release agent circulation and levelling; its main characteristic is definitely stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based form release agent can be used in moulds and items functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing form products are not only in order to let the mould release to boost productivity and lengthen the life of the form make use of. And can make the item clear, size qualified, and lower the technology of scrap, that is an essential supplementary important to forms and products – concrete additive.

Concrete release agent plays an important role within modern building construction; its principal role is always to create a layer of remoteness motion picture between the template and the concrete surface to ensure that the template will not stick to the concrete area to ensure that it is simpler to take apart the form after putting and to maintain the end of the concrete area. Here, we will present the sorts, features, usage and application of concrete release agent in more detail.

Kinds of concrete release agent

Concrete release agents can be divided into many types in accordance with different category strategies, and the frequent classification techniques 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 emission agent for tunnels and and so forth.
• According to the the formula of: it can be divided into water-based concrete release representatives, petroleum-based concrete release agents, silicone oil concrete release brokers, etc.
• According to the utilization effect: it can be divided into ordinary concrete release brokers, simple to remove concrete release representatives, high-gloss concrete release representatives and etc.

Characteristics of Concrete release agent

A concrete release agent is also known as a concrete separation agent or mould release lubricant. It is actually a kind of material coated on the inner wall of the formwork to play the part of lubrication and isolation to ensure that the concrete may be easily detached from the formwork when taking apart the formwork, and the shape of the concrete can be kept intact and undamaged. Compared with the standard release substance motor oil or waste motor oil, the release agent has the advantages of easy release, no pollution of the concrete covering, no corrosion of the template, effortless to paint, low value and etc. However, not all types of concrete release brokers with a variety of materials made of templates are suitable for different supplies of the template and different development problems 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 following features:
Good remoteness performance: concrete release agent can develop a dense isolation film between the formwork and the concrete surface, efficiently preventing the formwork from bonding with the concrete covering and facilitating the dismantling.

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

Excellent anti-adhesion overall performance: concrete release agents can effectively prevent the formwork from bonding with the concrete covering, steering clear of the formwork from damaging the concrete surface when taking down the formwork.

Good waterproof performance: concrete release agent has good waterproof efficiency, which can successfully stop moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and enhancing the service life of the formwork.

Simple 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 surface.

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 area gradually. In case of tight bonding between the formwork and the concrete covering, tools can be used appropriately to assist in the taking apart.

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 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 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 boost 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 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 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 enhance the construction efficiency and quality of the development project and provide a strong guarantee for the growth of the building industry.
