What is actually a concrete release agent?

A concrete release agent is definitely a substance applied to the building template just before the concrete is added so that the template does not stick to to the concrete surface right after flowing, is not easy to take apart the cast or affects the end of the concrete area. Its principal role within the design and the concrete area to develop a motion picture that is going to be separated from the two can also be known as an remoteness agent.

A water-based release agent is definitely an crucial auxiliary in the release agent and can alter the water-based release agent stream and levelling; its primary attribute is stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based mould release agent is used in forms and items functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing form items aren’t just so as to let the mould release to boost productivity and lengthen the life of the form utilize. And can make the merchandise thoroughly clean, size qualified, and lower the technology of scrap, that is an essential additive important to casts and products – concrete additive.

Concrete release agent plays an important role inside modern building development; its primary role would be to create a layer of isolation film between the template and the concrete area so that the design does not stick to to the concrete area in order that it is simpler to take apart the mould right after putting and to maintain the end of the concrete surface. Here, we will introduce the kinds, characteristics, utilization and application of concrete release agent in more detail.

Types of concrete release agent

Concrete release agents can be divided into numerous kinds in accordance with different category strategies, and the typical grouping techniques are the following:

• According to the 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 etc.
• According to the formula of: it can be divided into water-based concrete release brokers, petroleum-based concrete release representatives, silicone oil concrete release agents, etc.
• According to the the utilization effect: it can be divided into ordinary concrete release brokers, simple to remove concrete release agents, high-gloss concrete release agents and etc.

Features of Concrete release agent

A concrete release agent is also referred to as a concrete remoteness agent or mould release lubricant. It is actually a sort of substance coated on the inner wall of the formwork to play the function of lubrication and isolation so that the concrete could be effortlessly detached from the formwork when dismantling the formwork, and the shape 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 benefits of simple release, no pollution of the concrete area, no corrosion of the template, effortless to paint, low price and etc. However, not all kinds of concrete release agents with a variety of materials made of templates are suitable for different materials of the template and different construction conditions and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.

As an important construction auxiliary material, concrete release agent has the following qualities:
Good remoteness overall performance: concrete release agent can form a dense separation movie between the formwork and the concrete covering, efficiently avoiding the formwork from bonding with the concrete surface and facilitating the removing.

Good lubrication performance: concrete release agent has good lubrication performance, which can reduce the friction between the formwork and concrete covering, lower the resistance during pouring and boost the construction effectiveness.

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

Excellent waterproof overall performance: concrete release agent has good waterproof efficiency, 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.

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 area.

Demolding: Demolding can be carried out after the concrete reaches the strength of demolding. When taking down 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 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 building projects, mainly including the following aspects:

Reinforced concrete structure: In the building of a reinforced concrete structure, concrete release agents 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 area 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 enhance 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 building 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 growth of the construction industry.
