What exactly is a concrete release agent?

A concrete release agent is actually a material put on the construction design before the concrete is added so that the template doesn’t stick to to the concrete surface right after putting, isn’t easy to dismantle the form or affects the finish of the concrete covering. Its primary role within the template and the concrete area to create a movie that will be separated from the two is additionally known as an separation agent.

A water-based release agent is definitely an important supplementary in the release agent and can change the water-based release agent stream and levelling; its main attribute is definitely stability to microorganisms and enzymes, which can decrease the expense of raw materials. A water-based form release agent is utilized in casts and goods functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing form items are not just to be able to let the mould release to boost productivity and prolong the life of the form utilize. And can make the item clear, size qualified, and reduce the creation of scrap, that is an crucial additional important to moulds and goods – concrete release agent.

Concrete release agent plays an crucial role inside modern building building; its primary role is always to create a layer of remoteness motion picture between the design and the concrete surface in order that the design will not stick to the concrete area to ensure that it is much easier to dismantle the mould following putting and to maintain the finish of the concrete surface. Here, we will present the kinds, qualities, usage and application of concrete release agent in detail.

Kinds of concrete release agent

Concrete release representatives can be divided into many sorts based on different classification methods, and the typical classification strategies are the following:

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

Characteristics of Concrete release agent

A concrete release agent can also be referred to as a concrete separation agent or mould release lubricant. It is actually a type of substance coated on the inner wall of the formwork to play the role of lubrication and remoteness to ensure that the concrete may be smoothly detached from the formwork when taking down the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the traditional release materials motor oil or waste motor oil, the release agent has the positive aspects of effortless release, no pollution of the concrete covering, no corrosion of the template, simple to paint, low cost and and so forth. However, not all types of concrete release brokers with a variety of supplies made of templates are suitable for different components of the template and different construction circumstances and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.

As an essential construction auxiliary material, concrete release agent has the next qualities:
Good isolation efficiency: concrete release agent can develop a dense remoteness movie between the formwork and the concrete covering, successfully preventing the formwork from bonding with the concrete surface and facilitating the removing.

Excellent lubrication overall performance: concrete release agent has good lubricating overall performance, which can lower the chaffing between the formwork and concrete area, lower the resistance during pouring and improve the construction efficiency.

Good anti-adhesion performance: concrete release agents can successfully prevent the formwork from bonding with the concrete surface, steering clear of the formwork from damaging the concrete covering when taking down the formwork.

Great waterproof overall performance: concrete release agent has good waterproof efficiency, which can efficiently stop moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and enhancing the service life of the formwork.

Effortless 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 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 covering.

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 surface 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 surface, 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 building of a reinforced concrete structure, concrete release brokers can be used for formwork isolation, preventing 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 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 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 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 essential 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 enhance the construction efficiency and quality of the development project and provide a strong guarantee for the growth of the development industry.
