What is actually a concrete release agent?

A concrete release agent is definitely a substance placed on the building template just before the concrete is put so the design will not stick to to the concrete area following putting, isn’t easy to dismantle the cast or influences the complete of the concrete covering. Its primary role in the template and the concrete surface to develop a movie that is going to be separated from the two is additionally known as an remoteness agent.

A water-based release agent is definitely an essential ancillary in the release agent and can alter the water-based release agent stream and levelling; its primary characteristic is definitely stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based cast release agent is utilized in forms and items functional processing ingredients; in the rubber, plastic, and Jinsu processing industry, manufacturing form goods are not only in order to let the cast release to improve productivity and extend the life of the form utilize. And can make the merchandise clean, size qualified, and decrease the technology of scrap, which can be an essential supplementary important to casts and goods – Water-based Concrete Release Agent.

Concrete release agent plays an essential role within modern building development; its main role is always to develop a layer of separation movie between the template and the concrete covering to ensure that the design doesn’t stick to to the concrete surface so that it is easier to take down the cast following flowing and to maintain the end of the concrete covering. Here, we will introduce the kinds, features, usage and application of concrete release agent in detail.

Kinds of concrete release agent

Concrete release representatives can be divided into many kinds in accordance with different category techniques, and the common category techniques 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 release agent for tunnels and so on.
• According to the formula of: it can be divided into water-based concrete release agents, oil-based concrete release representatives, silicone oil concrete release brokers, etc.
• According to the effect of use: it can be divided into ordinary concrete release agents, an easy task to remove concrete release brokers, high-gloss concrete release brokers and and so forth.

Features of Concrete release agent

A concrete release agent is additionally referred to as a concrete separation agent or mould release lubricant. It is really a sort of material coated on the inner wall of the formwork to play the role of lubricating and isolation to ensure that the concrete could be effortlessly detached from the formwork when dismantling the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the traditional release substance 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, simple to paint, low price and and so forth. However, not all sorts of concrete release agents with a selection of materials made of templates are suitable for different materials of the template and different development problems 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 subsequent characteristics:
Good isolation overall performance: concrete release agent can develop a dense separation film between the formwork and the concrete surface, efficiently stopping the formwork from bonding with the concrete surface and facilitating the dismantling.

Excellent lubrication overall performance: concrete release agent has good lubricating performance, which can reduce the rubbing between the formwork and concrete covering, decrease the resistance during pouring and enhance the construction productivity.

Good anti-adhesion performance: concrete release agents can successfully stop the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete surface when dismantling the formwork.

Good waterproof performance: concrete release agent has good waterproof performance, which can successfully stop moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and increasing the service life of the formwork.

Easy to use and safe: concrete release agent is effortless 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 area, tools can be used appropriately to assist in the taking down.

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 building of a reinforced concrete structure, concrete release brokers can be used for formwork isolation, avoiding formwork from bonding with concrete and increasing 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 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 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 building 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 improve the construction efficiency and quality of the development project and provide a strong guarantee for the advancement of the development industry.
