What exactly is a concrete release agent?

A concrete release agent is definitely a compound put on the building template just before the concrete is poured so that the design does not stick to to the concrete covering right after putting, is not simple to take down the form or impacts the finish of the concrete surface. Its principal role in the template and the concrete covering to develop a movie that is going to be separated from the two is also called an separation agent.

A water-based release agent is definitely an important ancillary in the release agent and can alter the water-based release agent circulation and levelling; its primary attribute is actually stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based mould release agent is used in casts and goods functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing cast products are not just so as to let the mould release to improve productivity and lengthen the life of the mould utilize. And can make the merchandise clean, size qualified, and reduce the creation of scrap, that is an essential additive vital to forms and products – concrete additive.

Concrete release agent plays an essential role within modern building building; its main role would be to develop a layer of separation motion picture between the design and the concrete surface in order that the template will not adhere to the concrete area in order that it is much easier to take apart the form following putting and to maintain the complete of the concrete area. Here, we will unveil the sorts, features, utilization and program of concrete release agent at length.

Kinds of concrete release agent

Concrete release representatives can be divided into several types in accordance with different classification methods, and the frequent category techniques are the following:

• According to the scope 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 formula 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 representatives, easy-to-remove concrete release brokers, high-gloss concrete release brokers and and so forth.

Characteristics of Concrete release agent

A concrete release agent can also be known as a concrete remoteness agent or mould release lubricant. It is a sort of compound coated on the inner wall of the formwork to play the function of lubricating and isolation to ensure that the concrete could be smoothly detached from the formwork when dismantling the formwork, and the condition of the concrete may 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 area, no corrosion of the template, effortless to paint, low cost and so on. 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 appropriate release agent in order to receive good results.

As an essential construction auxiliary material, concrete release agent has the following qualities:
Good remoteness performance: concrete release agent can create a dense remoteness movie between the formwork and the concrete area, effectively preventing the formwork from bonding with the concrete surface and facilitating the dismantling.

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

Good anti-adhesion efficiency: concrete release agents can effectively stop the formwork from bonding with the concrete covering, steering clear of the formwork from damaging the concrete area when dismantling the formwork.

Great waterproof efficiency: concrete release agent has good waterproof performance, which can successfully avoid moisture from penetrating between the formwork and concrete, preventing 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 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 covering.

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 area of the formwork should be knocked gently to separate the formwork from the concrete surface 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 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 construction projects, mainly including the following aspects:

Reinforced concrete structure: In the development of a reinforced concrete structure, concrete release agents can be used for formwork isolation, stopping 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 area 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 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 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 construction projects.

In conclusion, concrete release agent, as an essential 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 growth of the construction industry.
