What is a concrete release agent?

A concrete release agent is actually a compound put on the development template prior to the concrete is put so the template will not adhere to the concrete surface right after putting, isn’t effortless to dismantle the form or affects the finish of the concrete covering. Its primary role inside the template and the concrete area to create a movie that is going to be separated from the two is additionally called an separation agent.

A water-based release agent is definitely an essential supplementary within the release agent and can modify the water-based release agent stream and levelling; its principal characteristic is actually stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based mould release agent can be used in forms and goods functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing cast products aren’t just to be able to let the form release to enhance productivity and prolong the life of the mould use. And can make the product clean, size qualified, and lower the generation of scrap, which is an important supplementary important to moulds and products – concrete additive.

Concrete release agent plays an crucial role within modern building development; its principal role is to develop a layer of separation movie between the design and the concrete surface to ensure that the template doesn’t stick to the concrete surface in order that it is much easier to dismantle the cast after pouring and to maintain the finish of the concrete covering. Here, we will introduce the sorts, features, usage and use of concrete release agent in more detail.

Sorts of concrete release agent

Concrete release agents can be divided into many kinds according to different category strategies, and the typical category methods are as follows:

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

Characteristics of Concrete release agent

A concrete release agent is additionally called a concrete isolation agent or mould release lubricant. It is actually a sort of substance coated on the inner wall of the formwork to play the role of lubricating and remoteness 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 standard release substance motor oil or waste motor oil, the release agent has the benefits of simple release, no pollution of the concrete area, no corrosion of the template, easy to paint, low cost and and so forth. However, not all kinds of concrete release representatives with a array of materials made of templates are suitable for different supplies of the template and different building circumstances and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.

As an crucial construction auxiliary material, concrete release agent has the following features:
Good remoteness efficiency: concrete release agent can create a dense remoteness movie between the formwork and the concrete area, efficiently preventing the formwork from bonding with the concrete area and facilitating the demolding.

Excellent lubrication efficiency: concrete release agent has good lubrication performance, which can lower the chaffing between the formwork and concrete surface, decrease the resistance during pouring and improve the construction efficiency.

Good anti-adhesion overall performance: concrete release representatives can successfully prevent the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete covering when dismantling the formwork.

Excellent waterproof efficiency: concrete release agent has good waterproof efficiency, which can successfully prevent moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and improving 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 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 area.

Demolding: Demolding can be carried out after the concrete reaches the strength of demolding. When taking apart 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 surface 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 dismantling 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 building of a reinforced concrete structure, concrete release agents 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 surface, 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 enhance 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 crucial construction auxiliary material, plays an indispensable role in modern building projects. By choosing the right sort, the correct use method and a reasonable application field, can effectively enhance the construction efficiency and quality of the development project and provide a strong guarantee for the advancement of the building industry.
