What is a concrete release agent?

A concrete release agent is actually a material put on the development design just before the concrete is added so the design will not stick to the concrete surface after pouring, is just not easy to take down the mould or affects the finish of the concrete surface. Its main role inside the template and the concrete covering to form a movie that will be separated from the two is additionally referred to as an remoteness agent.

A water-based release agent is an crucial supplementary inside the release agent and can modify the water-based release agent circulation and levelling; its main characteristic is stability to microorganisms and enzymes, which can decrease the expense of raw materials. A water-based mould release agent is utilized in forms and products functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing cast items are not only to be able to let the form release to enhance productivity and prolong the life of the mould make use of. And can make the product clean, size qualified, and lower the creation of scrap, which is an important additional essential to moulds and items – concrete additive.

Concrete release agent plays an crucial role in modern building construction; its main role is to create a layer of separation movie between the design and the concrete surface so that the template doesn’t stick to the concrete area to ensure that it is easier to dismantle the form after pouring and to maintain the finish of the concrete area. Here, we will introduce the sorts, characteristics, utilization and program of concrete release agent at length.

Kinds of concrete release agent

Concrete release representatives can be divided into several types in accordance with different category techniques, and the frequent grouping techniques are the subsequent:

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

Characteristics of Concrete release agent

A concrete release agent can also be known as a concrete separation agent or mould release lubricant. It is a sort of substance coated on the inner wall of the formwork to play the role of lubrication and remoteness in order that the concrete can be easily detached from the formwork when taking down the formwork, and the form of the concrete may 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 covering, no corrosion of the template, effortless to paint, low value and so on. However, not all sorts of concrete release brokers with a variety of components made of templates are suitable for different components of the template and different building conditions and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.

As an essential construction auxiliary material, concrete release agent has the next features:
Good remoteness performance: concrete release agent can create a dense separation movie between the formwork and the concrete surface, successfully stopping the formwork from bonding with the concrete area and facilitating the demolding.

Great lubrication performance: concrete release agent has good lubricating efficiency, which can lower the rubbing between the formwork and concrete covering, reduce the resistance during pouring and enhance the construction effectiveness.

Good anti-adhesion performance: concrete release brokers can successfully prevent the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete area when taking apart the formwork.

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

Simple to use and safe: concrete release agent is simple 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 area, tools can be used appropriately to assist in the taking down.

Clean up the template: after taking apart 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 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 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 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 development projects.

In conclusion, concrete release agent, as an crucial construction auxiliary material, plays an indispensable role in modern development projects. By choosing the right kind, 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 building industry.
