What is actually a concrete release agent?

A concrete release agent is actually a material put on the construction template prior to the concrete is put so the design will not stick to the concrete covering after flowing, is not simple to dismantle the form or influences the complete of the concrete covering. Its principal role within the design and the concrete surface to create a film that will probably be separated from the two is also known as an separation agent.

A water-based release agent is surely an essential supplementary inside the release agent and can modify the water-based release agent stream and levelling; its main attribute is definitely stability to microorganisms and enzymes, which can lower the expense of raw materials. A water-based form release agent can be used in casts and items functional processing ingredients; in the rubber, plastic, and Jinsu processing market, manufacturing cast goods are not only in order to let the form release to enhance productivity and extend the life of the form make use of. And can make the product thoroughly clean, size qualified, and decrease the technology of scrap, that is an crucial additional important to casts and items – Water-based Concrete Release Agent.

Concrete release agent plays an essential role in modern building construction; its principal role is always to form a layer of isolation motion picture between the template and the concrete area to ensure that the template does not stick to to the concrete area to ensure that it is simpler to dismantle the mould right after flowing and to maintain the finish of the concrete surface. Here, we will unveil the sorts, qualities, usage and use of concrete release agent in detail.

Sorts of concrete release agent

Concrete release brokers can be divided into many kinds based on different category strategies, and the common grouping strategies are the following:

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

Characteristics of Concrete release agent

A concrete release agent is also known as a concrete remoteness agent or mould release lubricant. It is really a kind of substance coated on the inner wall of the formwork to play the part of lubricating and separation so 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 positive aspects of easy release, no pollution of the concrete surface, no corrosion of the template, effortless to paint, low price and etc. However, not all kinds of concrete release agents with a array of supplies made of templates are suitable for different supplies of the template and different development circumstances 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 following qualities:
Good isolation performance: concrete release agent can create a dense isolation film between the formwork and the concrete covering, efficiently stopping the formwork from bonding with the concrete surface and facilitating the dismantling.

Good lubrication overall performance: concrete release agent has good lubrication performance, which can decrease the friction between the formwork and concrete area, reduce the resistance during pouring and boost the construction productivity.

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

Great waterproof overall performance: concrete release agent has good waterproof performance, which can effectively avoid moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and increasing the service life of the formwork.

Simple 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 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 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 surface, 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 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, preventing 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 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 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 agents 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 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 boost the construction efficiency and quality of the building project and provide a strong guarantee for the growth of the development industry.
