What is a concrete release agent?

A concrete release agent is definitely a material put on the development template just before the concrete is added so the template does not adhere to the concrete area following putting, is just not effortless to take down the mould or influences the end of the concrete surface. Its primary role inside the design and the concrete area to develop a motion picture that will be separated from the two is also referred to as an separation agent.

A water-based release agent is definitely an important ancillary within the release agent and can change the water-based release agent circulation and levelling; its main feature is actually stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based mould release agent is used in moulds and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing market, manufacturing form products are not only so as to let the cast release to boost productivity and extend the life of the cast utilize. And can make the merchandise clean, size qualified, and reduce the technology of scrap, that is an important additive essential to moulds and goods – concrete release agent.

Concrete release agent plays an essential role within modern building construction; its principal role is always to form a layer of remoteness movie between the design and the concrete surface so that the template does not stick to to the concrete area to ensure that it is simpler to dismantle the mould following putting and to maintain the complete of the concrete covering. Here, we will introduce the sorts, features, usage and use of concrete release agent in detail.

Sorts of concrete release agent

Concrete release agents can be divided into numerous types according to different grouping methods, and the typical classification strategies are the following:

• According to the the scope of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete emission agent for tunnels and etc.
• According to the composition: it can be divided into water-based concrete release brokers, 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 representatives, easy-to-remove concrete release agents, high-gloss concrete release representatives and and so forth.

Qualities of Concrete release agent

A concrete release agent is also called a concrete separation agent or mould release lubricant. It is a kind of material coated on the inner wall of the formwork to play the function of lubricating and isolation in order that the concrete can be easily detached from the formwork when dismantling the formwork, and the condition of the concrete may 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 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 materials made of templates are suitable for different materials of the template and different building circumstances and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.

As an crucial construction auxiliary material, concrete release agent has the subsequent features:
Good isolation efficiency: concrete release agent can form a dense isolation motion picture between the formwork and the concrete covering, effectively avoiding the formwork from bonding with the concrete area and facilitating the removing.

Great lubrication overall performance: concrete release agent has good lubrication overall performance, which can reduce the rubbing between the formwork and concrete area, reduce the resistance during pouring and boost the construction effectiveness.

Excellent anti-adhesion performance: concrete release agents can effectively avoid the formwork from bonding with the concrete surface, steering clear of the formwork from damaging the concrete surface when taking apart the formwork.

Excellent waterproof efficiency: concrete release agent has good waterproof efficiency, which can effectively prevent moisture from penetrating between the formwork and concrete, avoiding 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 down 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 covering gradually. In case of tight bonding between the formwork and the concrete covering, tools can be used appropriately to assist in the dismantling.

Clean up the template: after dismantling 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 development projects, mainly including the following aspects:

Reinforced concrete structure: In the building of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, avoiding 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 covering 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 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 important construction auxiliary material, plays an indispensable role in modern building projects. By choosing the right sort, the correct use method and a reasonable application field, can effectively improve the construction efficiency and quality of the development project and provide a strong guarantee for the development of the development industry.
