What is a concrete release agent?

A concrete release agent is definitely a material placed on the development design prior to the concrete is poured so the template will not stick to to the concrete covering right after flowing, isn’t easy to take apart the form or impacts the end of the concrete surface. Its primary role within the design and the concrete surface to create a film that will be separated from the two is additionally known as an isolation agent.

A water-based release agent is surely an important supplementary inside the release agent and can change the water-based release agent stream and levelling; its primary feature is stability to microorganisms and enzymes, which can lower the expense of raw materials. A water-based mould release agent is utilized in moulds and goods functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing cast goods are not just in order to let the cast release to boost productivity and prolong the life of the form utilize. And can make the item thoroughly clean, size qualified, and reduce the technology of scrap, which can be an essential additive important to forms and goods – concrete additive.

Concrete release agent plays an crucial role in modern building development; its principal role is to form a layer of isolation movie between the template and the concrete covering in order that the template will not adhere to the concrete covering to ensure that it is easier to take down the mould after flowing and to maintain the finish of the concrete area. Here, we will introduce the kinds, features, usage and application of concrete release agent at length.

Types of concrete release agent

Concrete release agents can be divided into many types according to different category strategies, and the common 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 etc.
• According to the composition: it can be divided into water-based concrete release representatives, oil-based concrete release representatives, silicone oil concrete release agents, etc.
• According to the utilization effect: it can be divided into ordinary concrete release representatives, easy-to-remove concrete release brokers, high-gloss concrete release representatives and and so forth.

Features of Concrete release agent

A concrete release agent is also referred to as a concrete remoteness agent or mould release lubricant. It is a kind of material coated on the inner wall of the formwork to play the part of lubrication and separation so that the concrete could be effortlessly detached from the formwork when taking down the formwork, and the condition of the concrete can 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 simple release, no pollution of the concrete area, no corrosion of the template, simple to paint, low value and and so forth. However, not all sorts of concrete release agents with a variety of supplies made of templates are suitable for different supplies of the template and different construction problems 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 following qualities:
Good remoteness efficiency: concrete release agent can create a dense remoteness movie between the formwork and the concrete surface, efficiently preventing the formwork from bonding with the concrete area and facilitating the removing.

Great lubrication efficiency: concrete release agent has good lubrication overall performance, which can lower the chaffing between the formwork and concrete covering, decrease the resistance during pouring and boost the construction effectiveness.

Excellent anti-adhesion performance: concrete release representatives can efficiently stop the formwork from bonding with the concrete covering, steering clear of the formwork from damaging the concrete surface when taking apart the formwork.

Good waterproof overall performance: concrete release agent has good waterproof performance, which can efficiently avoid moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and enhancing the service life of the formwork.

Easy 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 apart the formwork, the connectors at the edge of the formwork should be dismantled first, and then the covering 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 surface, tools can be used appropriately to assist in the taking apart.

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 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 enhancing 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 area 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 brokers 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 important 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 development of the development industry.
