What is a concrete release agent?

A concrete release agent is definitely a substance put on the building template just before the concrete is poured in order that the template will not adhere to the concrete surface following putting, isn’t effortless to dismantle the cast or impacts the complete of the concrete area. Its primary role in the template and the concrete surface to form a film that is going to be separated from the two is additionally called an separation agent.

A water-based release agent is surely an important supplementary in the release agent and can alter the water-based release agent stream and levelling; its principal feature is definitely stability to microorganisms and enzymes, which can lower the expense of raw materials. A water-based cast release agent can be used in forms and goods functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing cast items are not just so as to let the form release to boost productivity and extend the life of the cast use. And can make the product thoroughly clean, size qualified, and lower the creation of scrap, which is an important supplementary important to forms and goods – concrete additive.

Concrete release agent plays an important role in modern building development; its primary role is always to create a layer of separation film between the template and the concrete surface so that the design does not stick to to the concrete covering in order that it is simpler to dismantle the form right after putting and to maintain the finish of the concrete area. Here, we will introduce the sorts, characteristics, utilization and use of concrete release agent in more detail.

Kinds of concrete release agent

Concrete release brokers can be divided into numerous kinds in accordance with different grouping techniques, and the frequent grouping methods are as follows:

• According to the the opportunity of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete launch agent for tunnels and and so forth.
• According to the the formula of: it can be divided into water-based concrete release agents, petroleum-based concrete release representatives, silicone oil concrete release representatives, etc.
• According to the effect of use: it can be divided into ordinary concrete release brokers, simple to remove concrete release brokers, high-gloss concrete release brokers and etc.

Qualities of Concrete release agent

A concrete release agent is also known as a concrete isolation agent or mould release lubricant. It is actually a sort of substance coated on the inner wall of the formwork to play the part of lubricating and remoteness so that the concrete could be easily detached from the formwork when taking apart the formwork, and the shape of the concrete can be kept intact and undamaged. Compared with the standard release substance motor oil or waste motor oil, the release agent has the benefits of effortless release, no pollution of the concrete covering, no corrosion of the template, easy to paint, low value and etc. However, not all sorts of concrete release agents with a array of supplies made of templates are suitable for different components of the template and different construction problems and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.

As an crucial construction auxiliary material, concrete release agent has the following qualities:
Good isolation overall performance: concrete release agent can develop a dense remoteness motion picture between the formwork and the concrete area, successfully preventing the formwork from bonding with the concrete covering and facilitating the demolding.

Good lubrication overall performance: concrete release agent has good lubricating efficiency, which can decrease the chaffing between the formwork and concrete surface, reduce the resistance during pouring and enhance the construction effectiveness.

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

Good waterproof efficiency: concrete release agent has good waterproof efficiency, which can effectively stop moisture from penetrating between the formwork and concrete, preventing 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 taking apart the formwork, the connectors at the edge of the formwork should be dismantled first, and then the area 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 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 building 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, preventing 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 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 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 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 important construction auxiliary material, plays an indispensable role in modern construction projects. By choosing the right type, 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.
