What exactly is a concrete release agent?

A concrete release agent is a material placed on the construction template just before the concrete is poured so that the template does not adhere to the concrete area following flowing, is just not simple to take down the cast or influences the finish of the concrete covering. Its primary role inside the template and the concrete area to develop a movie that will be separated from the two can also be referred to as an isolation agent.

A water-based release agent is definitely an crucial ancillary in the release agent and can change the water-based release agent flow and levelling; its primary feature is definitely stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based form release agent is used in casts and products functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing cast goods are not just so as to let the form release to boost productivity and extend the life of the mould utilize. And can make the product clear, size qualified, and lower the technology of scrap, which is an important supplementary vital to moulds and items – Water-based Concrete Release Agent.

Concrete release agent plays an crucial role in modern building construction; its main role is always to form a layer of isolation motion picture between the template and the concrete area to ensure that the design does not stick to to the concrete area so that it is simpler to dismantle the mould following flowing and to maintain the complete of the concrete covering. Here, we will unveil the sorts, qualities, use and application of concrete release agent in detail.

Kinds of concrete release agent

Concrete release agents can be divided into numerous sorts according to different classification techniques, and the common classification techniques are the following:

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

Features of Concrete release agent

A concrete release agent is also known as a concrete isolation agent or mould release lubricant. It is actually 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 effortlessly detached from the formwork when taking down the formwork, and the form of the concrete may be kept intact and undamaged. Compared with the conventional release substance 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 etc. However, not all sorts of concrete release agents with a array of materials made of templates are suitable for different components of the template and different development conditions 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 qualities:
Good separation overall performance: concrete release agent can develop a dense separation film between the formwork and the concrete area, efficiently avoiding the formwork from bonding with the concrete surface and facilitating the demolding.

Excellent lubrication performance: concrete release agent has good lubrication efficiency, which can decrease the rubbing between the formwork and concrete covering, decrease the resistance during pouring and boost the construction effectiveness.

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

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

Simple to use and safe: concrete release agent is effortless 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 taking down the formwork, the connectors at the edge of the formwork should be dismantled first, and then the covering 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 construction 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, 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 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 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 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 building 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 improve the construction efficiency and quality of the building project and provide a strong guarantee for the development of the construction industry.
