What is actually a concrete release agent?

A concrete release agent is a compound placed on the building template prior to the concrete is poured so the template will not stick to to the concrete covering after putting, is not easy to take down the mould or influences the complete of the concrete surface. Its main role in the template and the concrete area to create a movie that will be separated from the two can also be referred to as an remoteness agent.

A water-based release agent is an important ancillary in the release agent and can change the water-based release agent flow and levelling; its main attribute is stability to microorganisms and enzymes, which can decrease the expense of raw materials. A water-based mould release agent is utilized in forms and goods functional processing supplements; in the rubber, plastic, and Jinsu processing market, manufacturing cast items are not only so as to let the mould release to improve productivity and extend the life of the form utilize. And can make the merchandise clear, size qualified, and decrease the generation of scrap, which can be an important additive vital to casts and items – concrete release agent.

Concrete release agent plays an crucial role in modern building construction; its primary role would be to form a layer of separation movie between the design and the concrete surface in order that the design does not adhere to the concrete covering so that it is much easier to dismantle the form right after flowing and to maintain the end of the concrete area. Here, we will introduce the types, qualities, utilization and program of concrete release agent at length.

Sorts of concrete release agent

Concrete release representatives can be divided into many kinds in accordance with different grouping techniques, and the frequent classification techniques are the subsequent:

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

Features of Concrete release agent

A concrete release agent is additionally referred to as a concrete isolation agent or mould release lubricant. It is actually a kind of compound coated on the inner wall of the formwork to play the role of lubrication and remoteness so that the concrete could be smoothly detached from the formwork when taking down the formwork, and the condition of the concrete may be kept intact and undamaged. Compared with the conventional release material motor oil or waste motor oil, the release agent has the advantages of effortless release, no pollution of the concrete surface, no corrosion of the template, easy to paint, low cost and and so forth. However, not all types of concrete release agents with a selection of supplies made of templates are suitable for different supplies of the template and different building conditions 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 performance: concrete release agent can develop a dense remoteness film between the formwork and the concrete area, effectively avoiding the formwork from bonding with the concrete covering and facilitating the removing.

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

Great anti-adhesion overall performance: concrete release agents can successfully stop the formwork from bonding with the concrete surface, avoiding the formwork from damaging the concrete covering when taking down the formwork.

Excellent waterproof efficiency: concrete release agent has good waterproof performance, which can successfully prevent 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 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 surface.

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 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 dismantling.

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 building 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 increasing 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 area 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 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 development projects.

In conclusion, concrete release agent, as an essential construction auxiliary material, plays an indispensable role in modern development 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 construction project and provide a strong guarantee for the growth of the construction industry.
