What exactly is a concrete release agent?

A concrete release agent is actually a substance applied to the building template before the concrete is put so the template does not stick to to the concrete covering right after putting, is not easy to dismantle the form or influences the finish of the concrete area. Its main role inside the template and the concrete covering to form a movie that will be separated from the two can also be called an isolation agent.

A water-based release agent is an important supplementary within the release agent and can modify the water-based release agent flow and levelling; its principal characteristic is actually 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 market, manufacturing mould products are not only to be able to let the mould release to boost productivity and prolong the life of the form utilize. And can make the product thoroughly clean, size qualified, and reduce the creation of scrap, which is an crucial additional vital to forms and items – Water-based Concrete Release Agent.

Concrete release agent plays an important role within modern building building; its primary role is to create a layer of separation motion picture between the template and the concrete covering to ensure that the template does not adhere to the concrete covering in order that it is easier to dismantle the mould following putting and to maintain the finish of the concrete surface. Here, we will unveil the types, characteristics, usage and application of concrete release agent in detail.

Kinds of concrete release agent

Concrete release representatives can be divided into several types based on different category techniques, and the frequent grouping techniques are as follows:

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

Qualities of Concrete release agent

A concrete release agent is also referred to as a concrete isolation agent or mould release lubricant. It is actually a sort of material coated on the inner wall of the formwork to play the role of lubricating and separation to ensure that the concrete may be easily detached from the formwork when dismantling the formwork, and the shape of the concrete can be kept intact and undamaged. Compared with the standard release material motor oil or waste motor oil, the release agent has the advantages of simple release, no pollution of the concrete area, no corrosion of the template, easy to paint, low price and etc. However, not all sorts of concrete release agents with a selection of components made of templates are suitable for different materials of the template and different building circumstances 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 following qualities:
Good remoteness efficiency: concrete release agent can create a dense separation movie between the formwork and the concrete area, efficiently avoiding the formwork from bonding with the concrete area and facilitating the removing.

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

Good anti-adhesion performance: concrete release agents can efficiently stop the formwork from bonding with the concrete surface, avoiding the formwork from damaging the concrete surface when dismantling the formwork.

Excellent waterproof performance: concrete release agent has good waterproof overall performance, which can efficiently stop moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and enhancing 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 covering.

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 area 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 covering, tools can be used appropriately to assist in the taking apart.

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 building of a reinforced concrete structure, concrete release representatives 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 construction projects.

In conclusion, concrete release agent, as an essential 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 enhance the construction efficiency and quality of the development project and provide a strong guarantee for the growth of the building industry.
