What is a concrete release agent?

A concrete release agent is definitely a compound placed on the construction template before the concrete is poured so that the design will not stick to the concrete covering after flowing, isn’t simple to take apart the cast or influences the finish of the concrete area. Its main role in the template and the concrete covering to create a movie that is going to be separated from the two can also be known as an remoteness agent.

A water-based release agent is surely an crucial ancillary within the release agent and can modify the water-based release agent stream and levelling; its primary characteristic is definitely stability to microorganisms and enzymes, which can decrease the cost of raw materials. A water-based cast release agent can be used in casts and products functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing form products are not only so as to let the mould release to improve productivity and lengthen the life of the form use. And can make the merchandise clear, size qualified, and reduce the creation of scrap, that is an essential supplementary important to forms and items – concrete release agent.

Concrete release agent plays an important role in modern building building; its primary role is to form a layer of isolation motion picture between the design and the concrete covering to ensure that the template doesn’t stick to to the concrete area to ensure that it is much easier to take down the mould after flowing and to maintain the end of the concrete surface. Here, we will unveil the sorts, characteristics, usage and use of concrete release agent at length.

Sorts of concrete release agent

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

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

Qualities of Concrete release agent

A concrete release agent can also be known as a concrete isolation agent or mould release lubricant. It is really a sort of compound coated on the inner wall of the formwork to play the part of lubricating and isolation to ensure that the concrete could be easily detached from the formwork when taking down the formwork, and the shape of the concrete may be kept intact and undamaged. Compared with the standard release materials motor oil or waste motor oil, the release agent has the positive aspects of simple release, no pollution of the concrete area, no corrosion of the template, easy to paint, low price and and so forth. However, not all kinds of concrete release agents with a selection of components made of templates are suitable for different supplies of the template and different building problems 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 subsequent features:
Good remoteness overall performance: concrete release agent can form a dense remoteness movie between the formwork and the concrete area, successfully preventing the formwork from bonding with the concrete area and facilitating the dismantling.

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

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

Excellent waterproof performance: concrete release agent has good waterproof overall performance, which can successfully 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 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 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 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 covering 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 construction projects, mainly including the following aspects:

Reinforced concrete structure: In the building of a reinforced concrete structure, concrete release brokers can be used for formwork isolation, preventing 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 area, 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 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 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 construction projects.

In conclusion, concrete release agent, as an crucial construction auxiliary material, plays an indispensable role in modern building projects. By choosing the right type, 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 advancement of the development industry.
