What is a concrete release agent?

A concrete release agent is actually a compound placed on the construction design just before the concrete is poured so the template doesn’t stick to the concrete surface after putting, is just not easy to dismantle the form or influences the complete of the concrete covering. Its primary role in the template and the concrete area to form a movie that will probably be separated from the two can also be called an separation agent.

A water-based release agent is surely an crucial ancillary inside the release agent and can change the water-based release agent flow and levelling; its main characteristic is stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based form release agent can be used in moulds and products functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing form items are not only to be able to let the cast release to enhance productivity and prolong the life of the cast utilize. And can make the merchandise clean, size qualified, and reduce the creation of scrap, which is an essential supplementary essential to moulds and goods – Water-based Concrete Release Agent.

Concrete release agent plays an essential role inside modern building construction; its main role would be to form a layer of remoteness movie between the template and the concrete surface to ensure that the design does not stick to the concrete surface to ensure that it is easier to take down the form following pouring and to maintain the complete of the concrete covering. Here, we will introduce the types, features, usage and use of concrete release agent in detail.

Kinds of concrete release agent

Concrete release representatives can be divided into several sorts in accordance with different classification strategies, and the common category strategies are the subsequent:

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

Qualities of Concrete release agent

A concrete release agent is also known as a concrete separation agent or mould release lubricant. It is a sort of material coated on the inner wall of the formwork to play the part of lubrication and isolation to ensure that the concrete may 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 benefits of easy release, no pollution of the concrete surface, no corrosion of the template, effortless to paint, low value and so on. However, not all types of concrete release representatives with a selection of components made of templates are suitable for different materials of the template and different development circumstances and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.

As an essential construction auxiliary material, concrete release agent has the following features:
Good isolation efficiency: concrete release agent can form a dense isolation motion picture between the formwork and the concrete surface, efficiently avoiding the formwork from bonding with the concrete area and facilitating the dismantling.

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

Excellent anti-adhesion efficiency: concrete release representatives can effectively prevent the formwork from bonding with the concrete covering, preventing the formwork from damaging the concrete covering when taking apart the formwork.

Great waterproof overall performance: concrete release agent has good waterproof overall performance, which can effectively stop moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and improving the service life of the formwork.

Effortless 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 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 covering gradually. In case of tight bonding between the formwork and the concrete area, tools can be used appropriately to assist in the taking down.

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 building of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, stopping 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 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 boost 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 brokers 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 construction 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 growth of the building industry.
