What is actually a concrete release agent?

A concrete release agent is a material put on the development template just before the concrete is poured in order that the template doesn’t stick to to the concrete surface right after flowing, is not simple to take down the cast or impacts the end of the concrete surface. Its main role in the template and the concrete area to form a movie that is going to be separated from the two is also known as an isolation agent.

A water-based release agent is an crucial ancillary in the release agent and can modify the water-based release agent circulation and levelling; its primary feature is actually stability to microorganisms and enzymes, which can decrease the expense of raw materials. A water-based cast release agent can be used in forms and items functional processing supplements; in the rubber, plastic, and Jinsu processing market, manufacturing mould items are not just to be able to let the mould release to enhance productivity and extend the life of the mould utilize. And can make the merchandise thoroughly clean, size qualified, and lower the generation of scrap, which is an essential supplementary important to casts and products – Water-based Concrete Release Agent.

Concrete release agent plays an important role inside modern building development; its principal role is to develop a layer of separation movie between the template and the concrete area to ensure that the template does not stick to to the concrete covering in order that it is simpler to take apart the mould following pouring and to maintain the finish of the concrete covering. Here, we will present the types, features, usage and program of concrete release agent at length.

Kinds of concrete release agent

Concrete release agents can be divided into numerous kinds according to different category strategies, and the common category methods are the following:

• 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 and so forth.
• According to the composition of: it can be divided into water-based concrete release representatives, petroleum-based concrete release representatives, silicone oil concrete release representatives, etc.
• According to the use effect: it can be divided into ordinary concrete release representatives, simple to remove concrete release brokers, high-gloss concrete release representatives and etc.

Features of Concrete release agent

A concrete release agent is additionally referred to as a concrete remoteness agent or mould release lubricant. It is a sort of material coated on the inner wall of the formwork to play the function of lubricating and isolation so that the concrete may be easily detached from the formwork when taking apart the formwork, and the condition of the concrete can be kept intact and undamaged. Compared with the traditional release materials motor oil or waste motor oil, the release agent has the positive aspects of simple release, no pollution of the concrete covering, no corrosion of the template, easy to paint, low price and and so forth. However, not all sorts of concrete release brokers with a selection of supplies made of templates are suitable for different materials of the template and different development circumstances and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.

As an important construction auxiliary material, concrete release agent has the following features:
Good isolation efficiency: concrete release agent can develop a dense remoteness movie between the formwork and the concrete area, effectively stopping the formwork from bonding with the concrete area and facilitating the removing.

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

Great anti-adhesion efficiency: concrete release representatives can successfully stop the formwork from bonding with the concrete surface, steering clear of the formwork from damaging the concrete area when taking apart the formwork.

Excellent waterproof overall performance: concrete release agent has good waterproof efficiency, which can effectively stop moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and improving the service life of the formwork.

Easy 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 area.

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 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 brokers 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 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 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 important 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 building project and provide a strong guarantee for the development of the building industry.
