What is a concrete release agent?

A concrete release agent is definitely a compound put on the construction template prior to the concrete is put so the template doesn’t adhere to the concrete area after flowing, is not simple to take apart the form or impacts the complete of the concrete surface. Its primary role inside the template and the concrete area to develop a film that is going to be separated from the two can also be referred to as an isolation agent.

A water-based release agent is surely an important supplementary within the release agent and can alter the water-based release agent circulation and levelling; its principal attribute is definitely stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based cast release agent is utilized in casts and items functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing cast items are not only so as to let the mould release to improve productivity and lengthen the life of the mould make use of. And can make the item thoroughly clean, size qualified, and decrease the generation of scrap, that is an important supplementary important to casts and goods – Water-based Concrete Release Agent.

Concrete release agent plays an important role within modern building construction; its primary role would be to create a layer of remoteness movie between the design and the concrete area to ensure that the template does not stick to the concrete area so that it is much easier to take down the form after pouring and to maintain the finish of the concrete surface. Here, we will present the sorts, characteristics, usage and application of concrete release agent in more detail.

Kinds of concrete release agent

Concrete release representatives can be divided into numerous kinds according to different grouping techniques, 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 discharge agent for tunnels and and so forth.
• According to the formula of: it can be divided into water-based concrete release agents, oil-based concrete release agents, silicone oil concrete release representatives, etc.
• According to the the use effect: it can be divided into ordinary concrete release brokers, easy-to-remove concrete release brokers, high-gloss concrete release representatives and so on.

Features of Concrete release agent

A concrete release agent can also be called a concrete separation agent or mould release lubricant. It is really a kind of material coated on the inner wall of the formwork to play the role of lubrication and isolation in order that the concrete can be smoothly detached from the formwork when taking down the formwork, and the form of the concrete may 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 effortless release, no pollution of the concrete covering, no corrosion of the template, easy to paint, low cost and and so forth. However, not all sorts of concrete release brokers with a variety of materials made of templates are suitable for different materials 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 important construction auxiliary material, concrete release agent has the following qualities:
Good remoteness overall performance: concrete release agent can create a dense isolation movie between the formwork and the concrete area, effectively preventing the formwork from bonding with the concrete surface and facilitating the demolding.

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

Excellent anti-adhesion performance: concrete release representatives can successfully stop the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete surface when dismantling the formwork.

Excellent waterproof performance: concrete release agent has good waterproof efficiency, which can efficiently stop moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and increasing the service life of the formwork.

Easy 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 covering.

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 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 surface, 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 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, preventing 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 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 improve 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 essential construction auxiliary material, plays an indispensable role in modern building 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 growth of the building industry.
