What exactly is a concrete release agent?

A concrete release agent is a compound put on the building template before the concrete is poured in order that the template does not stick to the concrete surface following flowing, isn’t effortless to take apart the mould or influences the finish of the concrete surface. Its main role within the design and the concrete covering to develop a motion picture that will be separated from the two is also known as an remoteness agent.

A water-based release agent is definitely an important supplementary within the release agent and can alter the water-based release agent circulation and levelling; its principal characteristic is actually stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based form release agent is utilized in moulds and products functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing mould goods aren’t just to be able to let the cast release to enhance productivity and prolong the life of the form make use of. And can make the item clear, size qualified, and lower the creation of scrap, which can be an crucial additive essential to moulds and products – concrete additive.

Concrete release agent plays an crucial role inside modern building building; its principal role is to create a layer of remoteness film between the template and the concrete covering to ensure that the template doesn’t stick to the concrete covering to ensure that it is easier to dismantle the cast following pouring and to maintain the finish of the concrete area. Here, we will unveil the kinds, characteristics, use and application of concrete release agent in detail.

Kinds of concrete release agent

Concrete release agents can be divided into many sorts according to different category strategies, and the typical category methods are as follows:

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

Characteristics of Concrete release agent

A concrete release agent can also be known as a concrete isolation agent or mould release lubricant. It is actually a kind of compound coated on the inner wall of the formwork to play the function of lubricating and isolation to ensure that the concrete can be effortlessly detached from the formwork when taking apart the formwork, and the form of the concrete could 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 easy release, no pollution of the concrete surface, no corrosion of the template, easy to paint, low price and etc. However, not all types of concrete release agents with a selection of materials made of templates are suitable for different supplies of the template and different development conditions and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.

As an crucial construction auxiliary material, concrete release agent has the next qualities:
Good remoteness overall performance: concrete release agent can develop a dense remoteness movie between the formwork and the concrete covering, efficiently stopping the formwork from bonding with the concrete area and facilitating the demolding.

Excellent lubrication efficiency: concrete release agent has good lubrication efficiency, which can reduce the friction between the formwork and concrete surface, lower the resistance during pouring and improve the construction effectiveness.

Good anti-adhesion overall performance: concrete release agents can successfully avoid the formwork from bonding with the concrete covering, preventing the formwork from damaging the concrete area when taking apart the formwork.

Excellent waterproof overall performance: concrete release agent has good waterproof overall performance, which can successfully prevent moisture from penetrating between the formwork and concrete, avoiding 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 petroleum-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 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 area, 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 building projects, mainly including the following aspects:

Reinforced concrete structure: In the construction of a reinforced concrete structure, concrete release agents 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 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 representatives 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 development 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 building project and provide a strong guarantee for the advancement of the development industry.
