What is actually a concrete release agent?

A concrete release agent is actually a material applied to the construction template prior to the concrete is added so that the design does not adhere to the concrete area right after pouring, isn’t effortless to dismantle the cast or influences the finish of the concrete area. Its primary role within the design and the concrete surface to develop 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 an important ancillary in the release agent and can modify the water-based release agent stream and levelling; its primary feature is stability to microorganisms and enzymes, which can decrease the cost of raw materials. A water-based form release agent can be used in moulds and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing mould goods are not just to be able to let the form release to boost productivity and prolong the life of the cast utilize. And can make the item thoroughly clean, size qualified, and reduce the technology of scrap, which can be an important supplementary essential to moulds and items – Water-based Concrete Release Agent.

Concrete release agent plays an crucial role in modern building construction; its main role is always to create a layer of separation motion picture between the design and the concrete area to ensure that the design will not adhere to the concrete surface in order that it is simpler to dismantle the cast after pouring and to maintain the finish of the concrete covering. Here, we will unveil the sorts, characteristics, utilization and use of concrete release agent in detail.

Types of concrete release agent

Concrete release agents can be divided into numerous types in accordance with different grouping methods, and the frequent category 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 discharge agent for tunnels and and so forth.
• According to the composition of: it can be divided into water-based concrete release representatives, oil-based concrete release agents, silicone oil concrete release brokers, etc.
• According to the utilization effect: it can be divided into ordinary concrete release representatives, an easy task to remove concrete release agents, high-gloss concrete release representatives and etc.

Features of Concrete release agent

A concrete release agent can also be known as a concrete remoteness agent or mould release lubricant. It is really a sort of substance coated on the inner wall of the formwork to play the function of lubrication and remoteness so that the concrete may 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 materials motor oil or waste motor oil, the release agent has the positive aspects of effortless release, no pollution of the concrete surface, no corrosion of the template, easy to paint, low cost and and so forth. However, not all sorts of concrete release representatives with a selection of components made of templates are suitable for different materials of the template and different development conditions 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 next features:
Good remoteness overall performance: concrete release agent can form a dense isolation movie between the formwork and the concrete surface, successfully stopping the formwork from bonding with the concrete covering and facilitating the demolding.

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

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

Great waterproof overall performance: concrete release agent has good waterproof overall performance, which can effectively avoid 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 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 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 surface 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 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, stopping 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 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 surface 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 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 building projects.

In conclusion, concrete release agent, as an crucial construction auxiliary material, plays an indispensable role in modern construction projects. By choosing the right sort, the correct use method and a reasonable application field, can effectively improve the construction efficiency and quality of the construction project and provide a strong guarantee for the development of the building industry.
