Sustainable Construction Practices: Water-Based Concrete Release Agents

What exactly is a concrete release agent?

A concrete release agent is a substance applied to the construction template prior to the concrete is added so the template will not adhere to the concrete area following pouring, is just not effortless to take down the form or impacts the finish of the concrete covering. Its principal role inside the template and the concrete covering to form a movie that will probably be separated from the two is also called an separation agent.

A water-based release agent is definitely an important ancillary inside the release agent and can modify the water-based release agent flow and levelling; its main characteristic is definitely stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based mould release agent is used in casts and products functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing mould products are not only so as to let the mould release to enhance productivity and lengthen the life of the cast utilize. And can make the item clear, size qualified, and reduce the technology of scrap, which is an crucial supplementary vital to casts and products – concrete release agent.

Concrete release agent plays an important role inside modern building construction; its principal role is to create a layer of remoteness film between the template and the concrete covering in order that the design does not stick to the concrete covering to ensure that it is much easier to dismantle the form right after putting and to maintain the end of the concrete covering. Here, we will introduce the kinds, features, usage and use of concrete release agent in more detail.

Types of concrete release agent

Concrete release brokers can be divided into many kinds based on different classification strategies, and the typical category techniques are as follows:

  • According to the scope of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete emission 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 agents, silicone oil concrete release brokers, etc.
  • According to the use effect: it can be divided into ordinary concrete release agents, an easy task to remove concrete release agents, high-gloss concrete release brokers and and so forth.

Characteristics of Concrete release agent

A concrete release agent is also referred to as a concrete remoteness agent or mould release lubricant. It is a type of material coated on the inner wall of the formwork to play the part of lubrication and isolation so that the concrete can be easily detached from the formwork when taking apart the formwork, and the condition of the concrete may be kept intact and undamaged. Compared with the standard release substance motor oil or waste motor oil, the release agent has the positive aspects of simple release, no pollution of the concrete surface, no corrosion of the template, effortless to paint, low cost and so on. However, not all types of concrete release agents with a variety of components made of templates are suitable for different supplies of the template and different construction conditions 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 next qualities:
Good isolation overall performance: concrete release agent can create a dense isolation film between the formwork and the concrete area, efficiently stopping the formwork from bonding with the concrete covering and facilitating the removing.

Great lubrication performance: concrete release agent has good lubrication performance, which can lower the chaffing between the formwork and concrete area, reduce the resistance during pouring and improve the construction productivity.

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

Excellent waterproof performance: concrete release agent has good waterproof performance, which can effectively avoid moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and increasing 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 oil-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 covering 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 dismantling.

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 development of a reinforced concrete structure, concrete release brokers 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 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 boost 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 enhance 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 construction projects.

In conclusion, concrete release agent, as an essential construction auxiliary material, plays an indispensable role in modern development projects. By choosing the right kind, 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 advancement of the building industry.
