What is a concrete release agent?

A concrete release agent is actually a substance put on the development template prior to the concrete is added in order that the design does not adhere to the concrete surface right after putting, is not effortless to take down the mould or impacts the end of the concrete covering. Its main role within the template and the concrete area to form a motion picture that will be separated from the two can also be called an remoteness agent.

A water-based release agent is surely an important auxiliary in the release agent and can alter the water-based release agent stream and levelling; its primary feature is stability to microorganisms and enzymes, which can decrease the expense of raw materials. A water-based form release agent is used in casts and items functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing mould goods are not just to be able to let the cast release to improve productivity and lengthen the life of the cast utilize. And can make the merchandise thoroughly clean, size qualified, and lower the generation of scrap, which can be an essential supplementary vital to moulds and items – concrete additive.

Concrete release agent plays an crucial role in modern building development; its main role is to form a layer of isolation motion picture between the design and the concrete covering in order that the design will not stick to to the concrete surface so that it is much easier to dismantle the cast right after putting and to maintain the finish of the concrete covering. Here, we will present the types, characteristics, usage and program of concrete release agent in more detail.

Types of concrete release agent

Concrete release representatives can be divided into numerous kinds based on different classification methods, and the frequent category techniques are as follows:

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

Characteristics of Concrete release agent

A concrete release agent is also called a concrete isolation agent or mould release lubricant. It is actually a kind of compound coated on the inner wall of the formwork to play the part of lubrication and isolation so that the concrete could 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 standard release materials motor oil or waste motor oil, the release agent has the advantages of simple release, no pollution of the concrete covering, no corrosion of the template, effortless to paint, low value and etc. However, not all kinds of concrete release agents with a selection 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 suitable release agent in order to receive good results.

As an essential construction auxiliary material, concrete release agent has the next features:
Good remoteness overall performance: concrete release agent can form a dense remoteness film between the formwork and the concrete area, successfully stopping the formwork from bonding with the concrete area and facilitating the removing.

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

Good anti-adhesion efficiency: concrete release representatives can successfully stop the formwork from bonding with the concrete covering, avoiding the formwork from damaging the concrete covering when taking apart the formwork.

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

Simple 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 taking down 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 area 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 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 construction of a reinforced concrete structure, concrete release brokers 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 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 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 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 type, 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 building industry.
