What is a concrete release agent?

A concrete release agent is definitely a compound placed on the construction template before the concrete is poured so that the design doesn’t adhere to the concrete surface following flowing, is not effortless to take down the cast or influences the finish of the concrete surface. Its main role within the template and the concrete covering to develop a motion picture that is going to be separated from the two is also called an isolation agent.

A water-based release agent is an important ancillary in the release agent and can modify the water-based release agent circulation and levelling; its main characteristic is actually stability to microorganisms and enzymes, which can decrease the price of raw materials. A water-based cast release agent is used in casts and products functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing mould items are not only so as to let the mould release to boost productivity and prolong the life of the cast make use of. And can make the merchandise clear, size qualified, and decrease the creation of scrap, which is an important additive vital to forms and goods – Water-based Concrete Release Agent.

Concrete release agent plays an crucial role within modern building building; its main role would be to develop a layer of remoteness film between the template and the concrete area in order that the template does not stick to to the concrete covering so that it is easier to take apart the cast right after putting and to maintain the end of the concrete covering. Here, we will present the sorts, features, usage and program of concrete release agent in detail.

Kinds of concrete release agent

Concrete release agents can be divided into numerous kinds in accordance with different category techniques, and the frequent grouping strategies are the subsequent:

• According to the scope of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete release agent for tunnels and so on.
• 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 effect of use: it can be divided into ordinary concrete release representatives, simple to remove concrete release brokers, high-gloss concrete release representatives and and so forth.

Qualities of Concrete release agent

A concrete release agent is also known as a concrete remoteness agent or mould release lubricant. It is a type of substance coated on the inner wall of the formwork to play the role of lubricating and remoteness to ensure that the concrete may be easily detached from the formwork when taking down the formwork, and the form 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 effortless release, no pollution of the concrete surface, no corrosion of the template, effortless to paint, low value and etc. However, not all types of concrete release brokers with a selection of supplies made of templates are suitable for different supplies 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 important construction auxiliary material, concrete release agent has the subsequent features:
Good remoteness overall performance: concrete release agent can develop a dense isolation movie between the formwork and the concrete covering, efficiently avoiding the formwork from bonding with the concrete surface and facilitating the demolding.

Excellent lubrication efficiency: concrete release agent has good lubrication efficiency, which can reduce the rubbing between the formwork and concrete area, lower the resistance during pouring and boost the construction productivity.

Excellent anti-adhesion performance: concrete release representatives can effectively stop the formwork from bonding with the concrete covering, preventing the formwork from damaging the concrete surface when taking apart the formwork.

Good waterproof performance: concrete release agent has good waterproof performance, which can efficiently 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.

Simple 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 area gradually. In case of tight bonding between the formwork and the concrete surface, tools can be used appropriately to assist in the dismantling.

Clean up the template: after taking down 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 development of a reinforced concrete structure, concrete release agents 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 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 area 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 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 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 construction projects.

In conclusion, concrete release agent, as an crucial 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 boost the construction efficiency and quality of the construction project and provide a strong guarantee for the growth of the development industry.
