What is a concrete release agent?

A concrete release agent is a material placed on the development design just before the concrete is put in order that the template doesn’t stick to to the concrete covering right after putting, isn’t simple to take down the mould or affects the complete of the concrete covering. Its primary role inside the design and the concrete area to form a film that is going to be separated from the two can also be called an remoteness agent.

A water-based release agent is an important auxiliary in the release agent and can alter the water-based release agent circulation and levelling; its principal feature is stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based cast release agent is used in forms and items functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing cast products are not only so as to let the mould release to enhance productivity and lengthen the life of the cast utilize. And can make the item thoroughly clean, size qualified, and decrease the creation of scrap, that is an crucial additive important to casts and goods – concrete release agent.

Concrete release agent plays an essential role within modern building development; its principal role would be to form a layer of isolation film between the template and the concrete surface to ensure that the template does not stick to to the concrete area so that it is easier to take down the mould after putting and to maintain the end of the concrete area. Here, we will present the kinds, characteristics, use and use of concrete release agent in detail.

Sorts of concrete release agent

Concrete release agents can be divided into many sorts according to different classification strategies, and the common classification methods 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 launch agent for tunnels and etc.
• According to the the composition: it can be divided into water-based concrete release agents, oil-based concrete release brokers, 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 brokers, high-gloss concrete release representatives and so on.

Characteristics of Concrete release agent

A concrete release agent is additionally referred to as a concrete remoteness agent or mould release lubricant. It is a kind of material coated on the inner wall of the formwork to play the part of lubricating and remoteness so that the concrete can be effortlessly detached from the formwork when taking apart 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, easy to paint, low cost and and so forth. However, not all kinds of concrete release representatives with a selection of materials made of templates are suitable for different supplies of the template and different development conditions 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 subsequent qualities:
Good remoteness performance: concrete release agent can form a dense remoteness film between the formwork and the concrete surface, efficiently preventing the formwork from bonding with the concrete covering and facilitating the demolding.

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

Great anti-adhesion performance: concrete release brokers can successfully avoid the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete surface when dismantling the formwork.

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

Easy 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 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 covering.

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 surface 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 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 development of a reinforced concrete structure, concrete release brokers 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 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 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 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 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 enhance the construction efficiency and quality of the building project and provide a strong guarantee for the growth of the building industry.
