What is a concrete release agent?

A concrete release agent is actually a substance placed on the building template just before the concrete is poured so the template doesn’t adhere to the concrete covering after pouring, is not simple to dismantle the mould or impacts the end of the concrete covering. Its primary role in the design and the concrete surface to form a film that will be separated from the two is also called an isolation agent.

A water-based release agent is surely an crucial auxiliary in the release agent and can alter the water-based release agent flow and levelling; its main feature is actually stability to microorganisms and enzymes, which can lower the expense of raw materials. A water-based mould release agent can be used in forms and products functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing mould items aren’t just to be able to let the mould release to improve productivity and extend the life of the mould use. And can make the merchandise clear, size qualified, and decrease the generation of scrap, that is an essential additional vital to moulds and products – concrete additive.

Concrete release agent plays an essential role inside modern building construction; its primary role is to create a layer of remoteness film between the design and the concrete covering in order that the template will not adhere to the concrete covering to ensure that it is simpler to dismantle the mould right after flowing and to maintain the complete of the concrete area. Here, we will unveil the types, features, utilization and application of concrete release agent at length.

Kinds of concrete release agent

Concrete release brokers can be divided into many kinds in accordance with different category strategies, and the frequent classification techniques are the following:

• According to the opportunity of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete launch agent for tunnels and and so forth.
• According to the composition of: it can be divided into water-based concrete release agents, petroleum-based concrete release representatives, silicone oil concrete release brokers, etc.
• According to the the effect of use: it can be divided into ordinary concrete release agents, an easy task to remove concrete release representatives, 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 isolation agent or mould release lubricant. It is actually a sort of material coated on the inner wall of the formwork to play the function of lubrication and isolation in order that the concrete can be easily detached from the formwork when taking down the formwork, and the shape 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 easy release, no pollution of the concrete area, no corrosion of the template, easy to paint, low value and etc. However, not all kinds of concrete release representatives 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 ideal release agent in order to receive good results.

As an essential construction auxiliary material, concrete release agent has the following qualities:
Good isolation overall performance: concrete release agent can develop a dense remoteness film between the formwork and the concrete area, effectively avoiding the formwork from bonding with the concrete area and facilitating the dismantling.

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

Excellent anti-adhesion performance: concrete release brokers can effectively stop the formwork from bonding with the concrete area, preventing the formwork from damaging the concrete covering when dismantling the formwork.

Excellent waterproof overall performance: concrete release agent has good waterproof performance, which can successfully avoid moisture from penetrating between the formwork and concrete, avoiding 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 down 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 surface, 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 building of a reinforced concrete structure, concrete release agents can be used for formwork isolation, preventing 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 area, 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 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 building 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 development project and provide a strong guarantee for the growth of the building industry.
