What is a concrete release agent?

A concrete release agent is a material placed on the construction design prior to the concrete is added so that the design does not stick to to the concrete covering right after pouring, is not easy to dismantle the form or influences the complete of the concrete area. Its principal role in the template and the concrete surface to create a film that will probably be separated from the two is also known as an remoteness agent.

A water-based release agent is surely an essential auxiliary in the release agent and can alter the water-based release agent flow and levelling; its principal feature is definitely stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based cast release agent is utilized in casts and products functional processing additives; in the rubber, plastic, and Jinsu processing business, manufacturing form items are not just to be able to let the mould release to improve productivity and lengthen the life of the mould make use of. And can make the merchandise clean, size qualified, and reduce the technology of scrap, which is an essential supplementary vital to forms and products – Water-based Concrete Release Agent.

Concrete release agent plays an crucial role within modern building construction; its primary role would be to create a layer of isolation motion picture between the design and the concrete surface in order that the template doesn’t stick to the concrete surface so that it is simpler to take down the mould right after pouring and to maintain the complete of the concrete covering. Here, we will present the kinds, qualities, usage and application of concrete release agent at length.

Sorts of concrete release agent

Concrete release representatives can be divided into several kinds according to different category strategies, and the frequent classification methods are the subsequent:

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

Qualities of Concrete release agent

A concrete release agent is also referred to as a concrete separation agent or mould release lubricant. It is a kind of compound coated on the inner wall of the formwork to play the function of lubricating and separation to ensure that the concrete could be easily detached from the formwork when dismantling the formwork, and the shape of the concrete could be kept intact and undamaged. Compared with the standard release substance motor oil or waste motor oil, the release agent has the advantages of effortless release, no pollution of the concrete area, no corrosion of the template, effortless to paint, low value and and so forth. However, not all sorts of concrete release agents with a array of supplies made of templates are suitable for different supplies of the template and different building conditions and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.

As an important construction auxiliary material, concrete release agent has the next characteristics:
Good separation efficiency: concrete release agent can develop a dense remoteness film between the formwork and the concrete area, successfully preventing the formwork from bonding with the concrete surface and facilitating the dismantling.

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

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

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

Effortless 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 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 surface.

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 dismantling.

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 development projects, mainly including the following aspects:

Reinforced concrete structure: In the development of a reinforced concrete structure, concrete release brokers can be used for formwork isolation, stopping 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 covering, 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 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 improve 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 development projects.

In conclusion, concrete release agent, as an crucial construction auxiliary material, plays an indispensable role in modern construction 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 building project and provide a strong guarantee for the advancement of the development industry.
