What is a concrete release agent?

A concrete release agent is actually a material applied to the building design before the concrete is added so the template does not stick to to the concrete surface following flowing, is not easy to take down the mould or impacts the finish of the concrete surface. Its principal role within the template and the concrete surface to develop a movie that is going to be separated from the two can also be referred to as an separation 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 characteristic is actually stability to microorganisms and enzymes, which can lower the cost of raw materials. A water-based form release agent can be used in forms and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing mould products are not just to be able to let the form release to boost productivity and lengthen the life of the cast use. And can make the product clear, size qualified, and decrease the technology of scrap, which is an crucial additive important to moulds and goods – concrete release agent.

Concrete release agent plays an important role in modern building development; its principal role is to form a layer of separation film between the design and the concrete surface so that the design does not adhere to the concrete covering in order that it is much easier to take apart the cast right after pouring and to maintain the finish of the concrete area. Here, we will present the sorts, qualities, utilization and program of concrete release agent in detail.

Types of concrete release agent

Concrete release agents can be divided into numerous types in accordance with different grouping methods, and the typical grouping methods 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 discharge 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 agents, silicone oil concrete release representatives, etc.
• According to the effect of use: it can be divided into ordinary concrete release representatives, easy-to-remove concrete release representatives, high-gloss concrete release agents and so on.

Characteristics of Concrete release agent

A concrete release agent is also called 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 role of lubricating and remoteness so that the concrete could be smoothly detached from the formwork when taking apart the formwork, and the form of the concrete can be kept intact and undamaged. Compared with the standard release materials motor oil or waste motor oil, the release agent has the advantages of simple release, no pollution of the concrete surface, no corrosion of the template, easy to paint, low cost and so on. However, not all types of concrete release agents with a variety of components made of templates are suitable for different components 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 important construction auxiliary material, concrete release agent has the following features:
Good separation overall performance: concrete release agent can develop a dense separation film between the formwork and the concrete surface, successfully avoiding the formwork from bonding with the concrete covering and facilitating the dismantling.

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

Good anti-adhesion overall performance: concrete release brokers can effectively prevent the formwork from bonding with the concrete covering, steering clear of the formwork from damaging the concrete surface when taking apart the formwork.

Excellent waterproof overall performance: concrete release agent has good waterproof overall performance, which can successfully 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 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 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 surface 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 covering, tools can be used appropriately to assist in the taking down.

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 construction of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, avoiding 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 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 construction 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 boost the construction efficiency and quality of the development project and provide a strong guarantee for the development of the development industry.
