What is actually a concrete release agent?

A concrete release agent is actually a substance placed on the building template before the concrete is poured in order that the template will not stick to the concrete surface after flowing, is just not effortless to take down the cast or influences the complete of the concrete area. Its primary role in the template and the concrete surface to create a film that will be separated from the two is also known as an isolation agent.

A water-based release agent is an important auxiliary in the release agent and can alter the water-based release agent flow and levelling; its principal feature is stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based cast release agent is used in moulds and goods functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing form products aren’t just in order to let the form release to enhance productivity and lengthen the life of the mould use. And can make the item clear, size qualified, and decrease the generation of scrap, which can be an crucial additive vital to moulds and products – concrete additive.

Concrete release agent plays an crucial role in modern building construction; its principal role is to form a layer of separation motion picture between the template and the concrete covering so that the template does not stick to the concrete surface so that it is easier to dismantle the cast following flowing and to maintain the complete of the concrete area. Here, we will present the kinds, features, utilization and program of concrete release agent in detail.

Sorts of concrete release agent

Concrete release representatives can be divided into several kinds in accordance with different category strategies, and the typical classification techniques are as follows:

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

Characteristics of Concrete release agent

A concrete release agent can also be referred to as a concrete remoteness agent or mould release lubricant. It is really a kind of compound coated on the inner wall of the formwork to play the function of lubricating and separation in order that the concrete could be effortlessly detached from the formwork when taking down the formwork, and the shape of the concrete may be kept intact and undamaged. Compared with the traditional 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, simple to paint, low value and so on. However, not all types of concrete release representatives with a selection of materials made of templates are suitable for different components of the template and different building 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 following qualities:
Good isolation performance: concrete release agent can develop a dense remoteness movie between the formwork and the concrete area, efficiently stopping the formwork from bonding with the concrete surface and facilitating the dismantling.

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

Great anti-adhesion overall performance: concrete release representatives can successfully prevent the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete surface when taking apart the formwork.

Excellent waterproof performance: concrete release agent has good waterproof performance, which can efficiently stop moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and improving 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 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 surface.

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 area 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 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 building projects, mainly including the following aspects:

Reinforced concrete structure: In the building of a reinforced concrete structure, concrete release agents can be used for formwork isolation, stopping 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 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 area 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 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 construction project and provide a strong guarantee for the growth of the construction industry.
