Key Factors to Consider When Choosing Concrete Release Agents

What exactly is a concrete release agent?

A concrete release agent is definitely a material applied to the building template before the concrete is put so the design does not stick to the concrete area following pouring, is just not effortless to take apart the mould or influences the finish of the concrete area. Its main role inside the template and the concrete covering to form a movie that is going to be separated from the two can also be known as an separation agent.

A water-based release agent is surely an essential auxiliary inside the release agent and can alter the water-based release agent circulation and levelling; its primary feature is stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based form release agent is used in casts and products functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing cast products are not just in order to let the mould release to enhance productivity and prolong the life of the cast make use of. And can make the product thoroughly clean, size qualified, and lower the generation of scrap, which can be an important additional vital to casts and products – concrete release agent.

Concrete release agent plays an essential role inside modern building building; its main role is always to develop a layer of separation movie between the template and the concrete surface so that the template will not adhere to the concrete covering to ensure that it is easier to take down the mould after flowing and to maintain the end of the concrete covering. Here, we will present the sorts, characteristics, use and application of concrete release agent in detail.

Types of concrete release agent

Concrete release brokers can be divided into several types according to different grouping techniques, and the typical category techniques are the subsequent:

  • 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 composition: it can be divided into water-based concrete release agents, petroleum-based concrete release agents, silicone oil concrete release representatives, etc.
  • According to the use effect: it can be divided into ordinary concrete release agents, 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 additionally referred to as a concrete separation agent or mould release lubricant. It is actually a sort of material coated on the inner wall of the formwork to play the part of lubricating and separation to ensure that the concrete can be effortlessly detached from the formwork when taking apart the formwork, and the condition of the concrete may be kept intact and undamaged. Compared with the traditional release material motor oil or waste motor oil, the release agent has the positive aspects of easy release, no pollution of the concrete area, no corrosion of the template, simple to paint, low value and so on. However, not all kinds of concrete release brokers with a selection of materials made of templates are suitable for different components of the template and different building problems and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.

As an essential construction auxiliary material, concrete release agent has the subsequent qualities:
Good separation efficiency: concrete release agent can form a dense separation film between the formwork and the concrete covering, effectively avoiding the formwork from bonding with the concrete area and facilitating the dismantling.

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

Good anti-adhesion performance: concrete release agents can effectively stop the formwork from bonding with the concrete surface, avoiding the formwork from damaging the concrete surface when taking down the formwork.

Good waterproof overall performance: concrete release agent has good waterproof overall performance, which can successfully 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 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 covering.

Demolding: Demolding can be carried out after the concrete reaches the strength of demolding. When dismantling 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 covering, tools can be used appropriately to assist in the taking apart.

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 development projects, mainly including the following aspects:

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

In conclusion, concrete release agent, as an important construction auxiliary material, plays an indispensable role in modern construction 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 development project and provide a strong guarantee for the development of the construction industry.
