What is actually a concrete release agent?

A concrete release agent is actually a material placed on the development template just before the concrete is added so that the template does not stick to to the concrete covering right after pouring, isn’t easy to dismantle the mould or affects the complete of the concrete covering. Its primary role inside the template and the concrete surface to form a motion picture that is going to be separated from the two can also be called an remoteness agent.

A water-based release agent is definitely an essential ancillary within the release agent and can change the water-based release agent circulation and levelling; its primary characteristic is actually stability to microorganisms and enzymes, which can decrease the cost of raw materials. A water-based mould release agent is utilized in moulds and products functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing form items aren’t just so as to let the form release to enhance productivity and lengthen the life of the form utilize. And can make the product clean, size qualified, and reduce the technology of scrap, which is an crucial additive essential to moulds and products – concrete release agent.

Concrete release agent plays an important role inside modern building construction; its principal role would be to create a layer of separation film between the template and the concrete area so that the template will not stick to to the concrete surface in order that it is much easier to take down the cast right after putting and to maintain the complete of the concrete area. Here, we will present the types, characteristics, use and use of concrete release agent in detail.

Kinds of concrete release agent

Concrete release brokers can be divided into numerous types in accordance with different category techniques, and the frequent category strategies are the subsequent:

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

Qualities of Concrete release agent

A concrete release agent can also be known as a concrete separation agent or mould release lubricant. It is actually a type of compound coated on the inner wall of the formwork to play the part of lubrication and separation to ensure that the concrete can be smoothly detached from the formwork when taking apart the formwork, and the condition 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 area, no corrosion of the template, effortless to paint, low cost and and so forth. However, not all types of concrete release brokers with a array of supplies made of templates are suitable for different supplies of the template and different construction circumstances 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 following features:
Good separation performance: concrete release agent can develop a dense isolation motion picture between the formwork and the concrete covering, efficiently avoiding the formwork from bonding with the concrete area and facilitating the dismantling.

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

Great anti-adhesion efficiency: concrete release brokers can efficiently stop the formwork from bonding with the concrete covering, avoiding the formwork from damaging the concrete surface when taking down the formwork.

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

Easy to use and safe: concrete release agent is effortless 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 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 covering, tools can be used appropriately to assist in the taking down.

Clean up the template: after taking apart 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, 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 area 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 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 boost the construction efficiency and quality of the construction project and provide a strong guarantee for the development of the development industry.
