What is actually a concrete release agent?

A concrete release agent is a material put on the building template just before the concrete is put so the template doesn’t adhere to the concrete area right after pouring, is just not effortless to take down the mould or impacts the complete of the concrete covering. Its main role inside the template and the concrete surface to form a film that will probably be separated from the two is also called an remoteness agent.

A water-based release agent is surely an important ancillary inside the release agent and can alter 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 cast release agent can be used in moulds and items functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing cast goods are not only in order to let the mould release to enhance productivity and prolong the life of the form make use of. And can make the merchandise clean, size qualified, and lower the technology of scrap, which is an important additive essential to casts and products – Water-based Concrete Release Agent.

Concrete release agent plays an essential role in modern building building; its primary role is to develop a layer of separation film between the design and the concrete area to ensure that the template will not stick to the concrete covering in order that it is much easier to take down the mould right after putting and to maintain the end of the concrete covering. Here, we will unveil the kinds, qualities, usage and program of concrete release agent in more detail.

Sorts of concrete release agent

Concrete release representatives can be divided into many kinds in accordance with different category methods, and the typical category techniques are the following:

• According to the opportunity of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete launch agent for tunnels and and so forth.
• According to the composition of: it can be divided into water-based concrete release representatives, petroleum-based concrete release representatives, silicone oil concrete release representatives, etc.
• According to the use effect: it can be divided into ordinary concrete release brokers, an easy task to remove concrete release representatives, high-gloss concrete release representatives and etc.

Features of Concrete release agent

A concrete release agent is also known as a concrete remoteness agent or mould release lubricant. It is really a type of substance coated on the inner wall of the formwork to play the function of lubrication and separation to ensure that the concrete may be easily detached from the formwork when taking down the formwork, and the shape of the concrete can be kept intact and undamaged. Compared with the conventional release materials motor oil or waste motor oil, the release agent has the advantages of easy release, no pollution of the concrete covering, no corrosion of the template, effortless to paint, low value and etc. However, not all types of concrete release representatives with a variety of supplies made of templates are suitable for different components of the template and different development problems 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 next characteristics:
Good remoteness overall performance: concrete release agent can create a dense separation motion picture between the formwork and the concrete covering, effectively preventing the formwork from bonding with the concrete area and facilitating the removing.

Great lubrication efficiency: concrete release agent has good lubricating performance, which can reduce the friction between the formwork and concrete surface, reduce the resistance during pouring and boost the construction productivity.

Great anti-adhesion overall performance: concrete release agents can effectively prevent the formwork from bonding with the concrete covering, preventing the formwork from damaging the concrete surface when taking apart the formwork.

Great waterproof overall performance: concrete release agent has good waterproof overall performance, which can efficiently stop moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and increasing 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 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 covering 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 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 increasing 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 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 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 building projects.

In conclusion, concrete release agent, as an crucial construction auxiliary material, plays an indispensable role in modern construction projects. By choosing the right type, 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 growth of the development industry.
