What is actually a concrete release agent?

A concrete release agent is a substance applied to the building template just before the concrete is put so the design doesn’t stick to the concrete surface after pouring, is just not simple to take apart the mould or impacts the finish of the concrete surface. Its primary role in the design and the concrete covering to create a movie that will probably be separated from the two can also be called an remoteness agent.

A water-based release agent is definitely an important ancillary inside the release agent and can change the water-based release agent circulation and levelling; its primary attribute is actually stability to microorganisms and enzymes, which can reduce the expense of raw materials. A water-based form release agent is used in moulds and goods functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing mould goods aren’t just in order to let the mould release to boost productivity and prolong the life of the cast make use of. And can make the merchandise clean, size qualified, and decrease the generation of scrap, that is an important supplementary essential to forms and goods – concrete additive.

Concrete release agent plays an essential role in modern building development; its main role is always to develop a layer of remoteness movie between the template and the concrete surface so that the template will not adhere to the concrete area to ensure that it is much easier to take apart the cast following putting and to maintain the complete of the concrete area. Here, we will unveil the kinds, features, usage and application of concrete release agent at length.

Types of concrete release agent

Concrete release agents can be divided into many kinds according to different grouping methods, and the typical classification strategies 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 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 brokers, silicone oil concrete release representatives, etc.
• According to the use effect: it can be divided into ordinary concrete release agents, simple to remove concrete release agents, high-gloss concrete release representatives and so on.

Qualities of Concrete release agent

A concrete release agent can also be referred to as a concrete separation agent or mould release lubricant. It is really a sort of substance coated on the inner wall of the formwork to play the part of lubricating and remoteness to ensure that the concrete can be effortlessly detached from the formwork when taking apart the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the conventional release materials motor oil or waste motor oil, the release agent has the advantages of simple release, no pollution of the concrete area, no corrosion of the template, simple to paint, low price and so on. However, not all types of concrete release agents with a array of components 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 crucial construction auxiliary material, concrete release agent has the next features:
Good separation efficiency: concrete release agent can form a dense isolation film between the formwork and the concrete area, efficiently stopping the formwork from bonding with the concrete covering and facilitating the dismantling.

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

Good anti-adhesion efficiency: concrete release agents can successfully stop the formwork from bonding with the concrete surface, avoiding the formwork from damaging the concrete area when dismantling the formwork.

Good waterproof performance: concrete release agent has good waterproof performance, which can effectively stop 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 covering.

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 area, tools can be used appropriately to assist in the taking apart.

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 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 surface, 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 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 boost 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 crucial construction auxiliary material, plays an indispensable role in modern development 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 building project and provide a strong guarantee for the development of the construction industry.
