What exactly is a concrete release agent?

A concrete release agent is actually a compound put on the construction design just before the concrete is added so the template does not adhere to the concrete area following flowing, isn’t effortless to dismantle the mould or affects the finish of the concrete surface. Its main role within the template and the concrete area to form a movie that is going to be separated from the two is also known as an separation agent.

A water-based release agent is an essential ancillary in the release agent and can modify the water-based release agent circulation and levelling; its primary attribute is actually stability to microorganisms and enzymes, which can lower the cost of raw materials. A water-based mould release agent is used in moulds and products functional processing ingredients; in the rubber, plastic, and Jinsu processing market, manufacturing mould products are not just to be able to let the form release to improve productivity and extend the life of the cast use. And can make the merchandise clean, size qualified, and decrease the creation of scrap, which can be an essential supplementary vital to forms and goods – Water-based Concrete Release Agent.

Concrete release agent plays an crucial role in modern building building; its primary role would be to form a layer of isolation motion picture between the design and the concrete surface so that the template does not stick to the concrete covering in order that it is much easier to dismantle the mould after putting and to maintain the end of the concrete surface. Here, we will introduce the sorts, features, use and application of concrete release agent in more detail.

Types of concrete release agent

Concrete release agents can be divided into many types based on different category strategies, and the frequent classification methods are the following:

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

Qualities of Concrete release agent

A concrete release agent can also be known as a concrete remoteness agent or mould release lubricant. It is actually a type of compound coated on the inner wall of the formwork to play the part of lubricating and remoteness so that the concrete may be effortlessly detached from the formwork when dismantling the formwork, and the shape of the concrete can be kept intact and undamaged. Compared with the traditional release substance 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 cost and etc. However, not all sorts of concrete release brokers with a array of supplies made of templates are suitable for different components of the template and different building 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 next characteristics:
Good remoteness efficiency: concrete release agent can form a dense remoteness motion picture between the formwork and the concrete covering, effectively avoiding the formwork from bonding with the concrete area and facilitating the removing.

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

Excellent anti-adhesion performance: concrete release representatives can efficiently stop the formwork from bonding with the concrete surface, avoiding the formwork from damaging the concrete surface when taking down the formwork.

Great waterproof efficiency: concrete release agent has good waterproof performance, which can effectively stop moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and enhancing 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 area.

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 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 down 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, 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 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 surface 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 development projects.

In conclusion, concrete release agent, as an essential construction auxiliary material, plays an indispensable role in modern building 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 construction project and provide a strong guarantee for the development of the construction industry.
