Key Considerations for Proper Application of Concrete Release Agents

What exactly is a concrete release agent?

A concrete release agent is definitely a compound placed on the construction template just before the concrete is added so that the template will not stick to to the concrete covering right after flowing, is not easy to take down the mould or affects the complete of the concrete area. Its main role within the template and the concrete covering to form a movie that will probably be separated from the two is also called an remoteness agent.

A water-based release agent is an essential auxiliary in the release agent and can change the water-based release agent stream and levelling; its main attribute is actually stability to microorganisms and enzymes, which can lower the cost of raw materials. A water-based form release agent is used in casts and items functional processing ingredients; in the rubber, plastic, and Jinsu processing industry, manufacturing form items aren’t just so as to let the mould release to enhance productivity and lengthen the life of the form utilize. And can make the item thoroughly clean, size qualified, and reduce the technology of scrap, which is an essential supplementary vital to forms and products – concrete additive.

Concrete release agent plays an important role within modern building construction; its principal role is always to develop a layer of separation movie between the template and the concrete surface to ensure that the design will not adhere to the concrete area in order that it is easier to take apart the cast after putting and to maintain the end of the concrete surface. Here, we will present the kinds, characteristics, use and program of concrete release agent at length.

Types of concrete release agent

Concrete release agents can be divided into many sorts according to different classification techniques, and the typical classification strategies are the subsequent:

  • According to the opportunity of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete release agent for tunnels and and so forth.
  • According to the composition of: it can be divided into water-based concrete release brokers, petroleum-based concrete release representatives, silicone oil concrete release brokers, etc.
  • According to the utilization effect: it can be divided into ordinary concrete release brokers, easy-to-remove concrete release representatives, high-gloss concrete release brokers and etc.

Characteristics of Concrete release agent

A concrete release agent can also be called a concrete isolation agent or mould release lubricant. It is actually a kind of substance coated on the inner wall of the formwork to play the function of lubrication and remoteness in order that the concrete could be smoothly detached from the formwork when dismantling the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the standard release material motor oil or waste motor oil, the release agent has the positive aspects of simple release, no pollution of the concrete covering, no corrosion of the template, effortless to paint, low price and so on. However, not all sorts of concrete release brokers with a selection of components made of templates are suitable for different materials of the template and different building conditions 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 qualities:
Good remoteness overall performance: concrete release agent can form a dense isolation movie between the formwork and the concrete covering, successfully avoiding the formwork from bonding with the concrete area and facilitating the removing.

Great lubrication performance: concrete release agent has good lubricating performance, which can lower the rubbing between the formwork and concrete area, reduce the resistance during pouring and boost the construction effectiveness.

Excellent anti-adhesion performance: concrete release brokers can efficiently stop the formwork from bonding with the concrete surface, steering clear of the formwork from damaging the concrete area when taking apart the formwork.

Great waterproof overall performance: concrete release agent has good waterproof performance, which can successfully avoid moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and increasing the service life of the formwork.

Easy to use and safe: concrete release agent is easy 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 dismantling 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 covering gradually. In case of tight bonding between the formwork and the concrete area, 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 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, avoiding formwork from bonding with concrete and enhancing 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 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 improve 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 building projects.

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