What exactly is a concrete release agent?

A concrete release agent is a compound placed on the building design prior to the concrete is added so that the design will not adhere to the concrete area following flowing, isn’t easy to take down the mould or influences the end of the concrete area. Its main role in the template and the concrete covering to develop a movie that is going to be separated from the two can also be referred to as an isolation agent.

A water-based release agent is an essential auxiliary within the release agent and can alter the water-based release agent stream and levelling; its principal characteristic is definitely stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based mould release agent is utilized in forms and goods functional processing supplements; in the rubber, plastic, and Jinsu processing market, manufacturing mould products are not only so as to let the form release to improve productivity and extend the life of the cast use. And can make the merchandise clear, size qualified, and lower the generation of scrap, which can be an essential additional important to forms and goods – concrete additive.

Concrete release agent plays an crucial role in modern building development; its main role would be to develop a layer of separation movie between the design and the concrete covering so that the design will not adhere to the concrete covering to ensure that it is easier to take apart the form following flowing and to maintain the complete of the concrete covering. Here, we will introduce the kinds, qualities, usage and use of concrete release agent at length.

Kinds of concrete release agent

Concrete release representatives can be divided into numerous types based on different grouping methods, and the typical grouping strategies are the following:

• According to the scope of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete discharge agent for tunnels and and so forth.
• According to the the composition 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 utilization effect: it can be divided into ordinary concrete release brokers, an easy task to remove concrete release agents, high-gloss concrete release agents and and so forth.

Features of Concrete release agent

A concrete release agent can also be referred to as a concrete isolation agent or mould release lubricant. It is really a type of compound coated on the inner wall of the formwork to play the function of lubricating and isolation to ensure that the concrete can 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 standard release material motor oil or waste motor oil, the release agent has the advantages of easy release, no pollution of the concrete surface, no corrosion of the template, easy to paint, low price and so on. However, not all sorts of concrete release brokers with a selection 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 suitable release agent in order to receive good results.

As an crucial construction auxiliary material, concrete release agent has the next features:
Good isolation overall performance: concrete release agent can develop a dense remoteness motion picture between the formwork and the concrete covering, efficiently avoiding the formwork from bonding with the concrete surface and facilitating the dismantling.

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

Excellent anti-adhesion performance: concrete release agents can effectively avoid the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete covering when taking apart the formwork.

Good waterproof overall performance: concrete release agent has good waterproof performance, which can successfully avoid moisture from penetrating between the formwork and concrete, preventing 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 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 covering 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 construction projects, mainly including the following aspects:

Reinforced concrete structure: In the construction of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, stopping 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 surface 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 boost 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 building projects.

In conclusion, concrete release agent, as an essential construction auxiliary material, plays an indispensable role in modern development projects. By choosing the right type, the correct use method and a reasonable application field, can effectively enhance the construction efficiency and quality of the development project and provide a strong guarantee for the growth of the construction industry.
