What is a concrete release agent?

A concrete release agent is actually a substance put on the building template before the concrete is added so the design does not adhere to the concrete covering after putting, isn’t effortless to dismantle the mould or influences the complete of the concrete area. Its principal role within the template and the concrete covering to form a film that is going to be separated from the two is also referred to as an separation agent.

A water-based release agent is surely an essential supplementary within the release agent and can alter the water-based release agent circulation and levelling; its principal attribute is stability to microorganisms and enzymes, which can lower the expense of raw materials. A water-based cast release agent is used in forms and goods functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing mould items are not only to be able to let the mould release to enhance productivity and prolong the life of the mould make use of. And can make the merchandise clean, size qualified, and decrease the creation of scrap, which is an essential additional important to moulds and items – concrete release agent.

Concrete release agent plays an essential role inside modern building building; its principal role is always to develop a layer of isolation film between the template and the concrete surface so that the design will not stick to the concrete surface in order that it is simpler to take apart the form right after flowing and to maintain the finish of the concrete surface. Here, we will present the sorts, characteristics, utilization and program of concrete release agent in detail.

Types of concrete release agent

Concrete release representatives can be divided into several types according to different category techniques, and the common grouping strategies are the subsequent:

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

Characteristics of Concrete release agent

A concrete release agent is additionally referred to as a concrete separation agent or mould release lubricant. It is really a sort of compound coated on the inner wall of the formwork to play the function of lubricating and separation in order that the concrete may be easily 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 substance motor oil or waste motor oil, the release agent has the advantages of easy release, no pollution of the concrete covering, no corrosion of the template, effortless to paint, low cost and etc. However, not all kinds of concrete release brokers with a selection of materials made of templates are suitable for different components of the template and different building circumstances and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.

As an essential construction auxiliary material, concrete release agent has the subsequent characteristics:
Good separation efficiency: concrete release agent can form a dense isolation motion picture between the formwork and the concrete surface, effectively avoiding the formwork from bonding with the concrete area and facilitating the demolding.

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

Excellent anti-adhesion performance: concrete release agents can efficiently avoid the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete covering when taking apart 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 increasing 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 covering.

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 area gradually. In case of tight bonding between the formwork and the concrete surface, tools can be used appropriately to assist in the taking apart.

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 agents can be used for formwork isolation, avoiding formwork from bonding with concrete and enhancing 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 covering, 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 covering 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 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 development projects. By choosing the right sort, the correct use method and a reasonable application field, can effectively improve the construction efficiency and quality of the construction project and provide a strong guarantee for the development of the construction industry.
