What is actually a concrete release agent?

A concrete release agent is actually a substance applied to the building template prior to the concrete is added so the design will not stick to to the concrete covering following flowing, isn’t simple to take apart the cast or influences the finish of the concrete surface. Its principal role in the template and the concrete surface to develop a movie that is going to be separated from the two is additionally referred to as an remoteness agent.

A water-based release agent is surely an crucial ancillary inside the release agent and can change the water-based release agent circulation and levelling; its primary attribute is definitely stability to microorganisms and enzymes, which can decrease the price of raw materials. A water-based form release agent is used in forms and products functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing mould goods aren’t just in order 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 generation of scrap, which can be an essential additive vital to forms and items – concrete additive.

Concrete release agent plays an important role in modern building construction; its primary role would be to form a layer of isolation motion picture between the design and the concrete surface in order that the template doesn’t stick to to the concrete covering in order that it is much easier to dismantle the mould after pouring and to maintain the end of the concrete covering. Here, we will unveil the sorts, characteristics, utilization and program of concrete release agent at length.

Kinds of concrete release agent

Concrete release representatives can be divided into many types based on different grouping techniques, and the frequent grouping strategies are the following:

• According to the the scope of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete emission 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, easy-to-remove concrete release representatives, high-gloss concrete release agents and so on.

Qualities of Concrete release agent

A concrete release agent is additionally referred to as a concrete isolation agent or mould release lubricant. It is really a kind of compound coated on the inner wall of the formwork to play the function of lubricating and remoteness in order that the concrete can be effortlessly detached from the formwork when dismantling the formwork, and the condition of the concrete could 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 covering, no corrosion of the template, easy to paint, low value and etc. However, not all types of concrete release agents with a array of materials made of templates are suitable for different supplies of the template and different building problems and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.

As an essential construction auxiliary material, concrete release agent has the subsequent features:
Good remoteness efficiency: concrete release agent can create a dense remoteness movie between the formwork and the concrete covering, successfully preventing the formwork from bonding with the concrete surface and facilitating the removing.

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

Good anti-adhesion efficiency: concrete release representatives can successfully stop the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete surface when taking apart the formwork.

Excellent waterproof 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 enhancing the service life of the formwork.

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

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 building projects, mainly including the following aspects:

Reinforced concrete structure: In the building of a reinforced concrete structure, concrete release brokers can be used for formwork isolation, preventing 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 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 boost 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 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 building projects.

In conclusion, concrete release agent, as an essential construction auxiliary material, plays an indispensable role in modern construction projects. By choosing the right kind, 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 advancement of the development industry.
