What exactly is a concrete release agent?

A concrete release agent is definitely a compound put on the building template prior to the concrete is added so the design does not adhere to the concrete area following pouring, is just not easy to dismantle the mould or impacts the finish of the concrete surface. Its main role within the template and the concrete surface to develop a motion picture that will be separated from the two can also be referred to as an remoteness agent.

A water-based release agent is surely an important ancillary inside the release agent and can change the water-based release agent circulation and levelling; its primary feature is definitely stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based form release agent can be used in forms and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing industry, manufacturing cast items are not just to be able to let the cast release to improve productivity and extend the life of the cast make use of. And can make the merchandise thoroughly clean, size qualified, and decrease the generation of scrap, which can be an crucial additional important to moulds and items – Water-based Concrete Release Agent.

Concrete release agent plays an essential role inside modern building building; its principal role is to develop a layer of separation film between the template and the concrete surface in order that the template doesn’t stick to the concrete area in order that it is simpler to dismantle the form after flowing and to maintain the finish of the concrete surface. Here, we will unveil the kinds, qualities, usage and application of concrete release agent at length.

Sorts of concrete release agent

Concrete release representatives can be divided into several kinds according to different classification techniques, and the common category strategies are the following:

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

Features of Concrete release agent

A concrete release agent is also referred to as a concrete separation agent or mould release lubricant. It is really a type of compound coated on the inner wall of the formwork to play the role of lubrication and remoteness so that the concrete may be easily detached from the formwork when dismantling the formwork, and the condition of the concrete can be kept intact and undamaged. Compared with the traditional release material motor oil or waste motor oil, the release agent has the benefits of simple release, no pollution of the concrete area, no corrosion of the template, simple to paint, low cost and so on. However, not all sorts of concrete release brokers with a variety 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 important construction auxiliary material, concrete release agent has the subsequent qualities:
Good isolation overall performance: concrete release agent can create a dense separation motion picture between the formwork and the concrete covering, successfully stopping the formwork from bonding with the concrete area and facilitating the demolding.

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

Great anti-adhesion overall performance: concrete release representatives can effectively prevent the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete area when dismantling the formwork.

Good waterproof performance: concrete release agent has good waterproof overall performance, which can efficiently prevent moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and enhancing 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 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 covering 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 development projects, mainly including the following aspects:

Reinforced concrete structure: In the development of a reinforced concrete structure, concrete release agents 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 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 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 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 construction 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 building project and provide a strong guarantee for the development of the building industry.
