What exactly is a concrete release agent?

A concrete release agent is a substance placed on the construction design prior to the concrete is poured so that the design doesn’t adhere to the concrete area right after putting, isn’t easy to take apart the mould or influences the complete of the concrete covering. Its main role inside the design and the concrete surface to develop a motion picture that will probably be separated from the two is also called an remoteness agent.

A water-based release agent is definitely an crucial auxiliary inside the release agent and can alter the water-based release agent circulation and levelling; its principal feature is actually 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 goods functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing mould products are not only to be able to let the cast release to enhance productivity and prolong the life of the mould utilize. And can make the merchandise clear, size qualified, and lower the creation of scrap, which is an essential additive essential to forms and items – concrete release agent.

Concrete release agent plays an crucial role inside modern building building; its principal role is always to form a layer of remoteness motion picture between the design and the concrete surface in order that the design doesn’t adhere to the concrete surface to ensure that it is easier to take down the mould following putting and to maintain the finish of the concrete surface. Here, we will unveil the sorts, features, use and use of concrete release agent in detail.

Kinds of concrete release agent

Concrete release brokers can be divided into several sorts in accordance with different classification strategies, and the common classification methods are the following:

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

Characteristics of Concrete release agent

A concrete release agent can also be called a concrete separation agent or mould release lubricant. It is a kind of substance coated on the inner wall of the formwork to play the part of lubrication and separation so that the concrete may be smoothly detached from the formwork when taking down the formwork, and the shape of the concrete may be kept intact and undamaged. Compared with the standard release material motor oil or waste motor oil, the release agent has the benefits of effortless release, no pollution of the concrete area, no corrosion of the template, simple to paint, low price and etc. However, not all sorts of concrete release brokers with a selection of supplies made of templates are suitable for different supplies of the template and different building circumstances and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.

As an essential construction auxiliary material, concrete release agent has the subsequent qualities:
Good remoteness efficiency: concrete release agent can create a dense isolation film between the formwork and the concrete area, effectively avoiding the formwork from bonding with the concrete surface and facilitating the removing.

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

Good anti-adhesion overall performance: concrete release representatives can effectively stop the formwork from bonding with the concrete covering, avoiding the formwork from damaging the concrete covering when dismantling the formwork.

Excellent waterproof overall performance: concrete release agent has good waterproof performance, which can effectively avoid moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and enhancing the service life of the formwork.

Effortless 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 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 covering.

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 area 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 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 construction of a reinforced concrete structure, concrete release brokers 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 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 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 construction projects.

In conclusion, concrete release agent, as an crucial construction auxiliary material, plays an indispensable role in modern construction projects. By choosing the right sort, the correct use method and a reasonable application field, can effectively boost the construction efficiency and quality of the building project and provide a strong guarantee for the development of the building industry.
