What is a concrete release agent?

A concrete release agent is a substance placed on the development template before the concrete is poured so that the template doesn’t stick to to the concrete covering after flowing, is just not simple to take down the form or affects the complete of the concrete surface. Its principal role inside the template and the concrete surface to develop a movie that will probably be separated from the two is additionally referred to as an remoteness agent.

A water-based release agent is definitely an important ancillary in the release agent and can modify the water-based release agent flow and levelling; its primary attribute is stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based form release agent is used in moulds and goods functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing form items aren’t just to be able to let the form release to improve productivity and lengthen the life of the cast use. And can make the product clear, size qualified, and lower the technology of scrap, that is an essential additive important to casts and products – concrete additive.

Concrete release agent plays an crucial role inside modern building construction; its main role is always to create a layer of remoteness motion picture between the template and the concrete area so that the template does not stick to the concrete area in order that it is much easier to take apart the cast right after flowing and to maintain the complete of the concrete covering. Here, we will unveil the kinds, features, usage and use of concrete release agent in more detail.

Sorts of concrete release agent

Concrete release representatives can be divided into numerous types in accordance with different classification methods, and the frequent grouping techniques are as follows:

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

Features of Concrete release agent

A concrete release agent can also be referred to 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 function of lubrication and isolation so 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, effortless to paint, low price and etc. However, not all types of concrete release agents with a array of supplies made of templates are suitable for different materials of the template and different construction problems and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.

As an important construction auxiliary material, concrete release agent has the subsequent features:
Good isolation overall performance: concrete release agent can form a dense separation film between the formwork and the concrete covering, successfully preventing the formwork from bonding with the concrete area and facilitating the demolding.

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

Great anti-adhesion overall performance: concrete release brokers can effectively avoid the formwork from bonding with the concrete covering, steering clear of the formwork from damaging the concrete surface when dismantling the formwork.

Excellent waterproof overall performance: concrete release agent has good waterproof efficiency, which can effectively avoid moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and improving the service life of the formwork.

Simple 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 surface.

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 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 building of a reinforced concrete structure, concrete release agents 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 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 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 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 construction projects.

In conclusion, concrete release agent, as an important 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 boost the construction efficiency and quality of the building project and provide a strong guarantee for the growth of the development industry.
