What exactly is a concrete release agent?

A concrete release agent is definitely a compound applied to the development template before the concrete is put so that the template does not adhere to the concrete surface following 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 will be separated from the two is additionally known as an separation agent.

A water-based release agent is an essential supplementary within the release agent and can alter the water-based release agent circulation and levelling; its principal characteristic is stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based form release agent is used in casts and items functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing cast goods are not just in order to let the mould release to enhance productivity and prolong the life of the mould use. And can make the merchandise clear, size qualified, and reduce the creation of scrap, that is an essential additive vital to forms and products – Water-based Concrete Release Agent.

Concrete release agent plays an crucial role within modern building development; its primary role is to create a layer of isolation motion picture between the design and the concrete surface so that the template does not stick to the concrete area so that it is easier to take apart the cast right after pouring and to maintain the complete of the concrete area. Here, we will introduce the sorts, features, utilization and use of concrete release agent at length.

Sorts of concrete release agent

Concrete release brokers can be divided into numerous sorts based on different grouping strategies, and the frequent classification strategies are the subsequent:

• According to the opportunity of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete release agent for tunnels and so on.
• According to the 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 brokers, simple to remove concrete release representatives, high-gloss concrete release agents and etc.

Characteristics of Concrete release agent

A concrete release agent can also be 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 lubrication and isolation to ensure that the concrete could be smoothly detached from the formwork when taking apart the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the standard release material motor oil or waste motor oil, the release agent has the advantages of effortless release, no pollution of the concrete covering, no corrosion of the template, effortless to paint, low value and etc. However, not all kinds of concrete release brokers with a selection of components made of templates are suitable for different supplies of the template and different construction circumstances and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.

As an crucial construction auxiliary material, concrete release agent has the next qualities:
Good separation performance: concrete release agent can form a dense isolation film between the formwork and the concrete covering, successfully avoiding the formwork from bonding with the concrete surface and facilitating the dismantling.

Excellent lubrication efficiency: concrete release agent has good lubrication efficiency, which can reduce the rubbing between the formwork and concrete surface, reduce the resistance during pouring and enhance the construction effectiveness.

Good anti-adhesion overall performance: concrete release brokers can efficiently stop the formwork from bonding with the concrete covering, avoiding the formwork from damaging the concrete surface when taking apart the formwork.

Good waterproof efficiency: concrete release agent has good waterproof efficiency, which can successfully avoid moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and enhancing the service life of the formwork.

Effortless to use and safe: concrete release agent is effortless 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 surface of the formwork should be knocked gently to separate the formwork from the concrete area gradually. In case of tight bonding between the formwork and the concrete surface, tools can be used appropriately to assist in the dismantling.

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 construction projects, mainly including the following aspects:

Reinforced concrete structure: In the construction of a reinforced concrete structure, concrete release agents 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 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 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 type, the correct use method and a reasonable application field, can effectively enhance the construction efficiency and quality of the building project and provide a strong guarantee for the advancement of the construction industry.
