What is a concrete release agent?

A concrete release agent is actually a substance applied to the building template just before the concrete is added in order that the template does not stick to the concrete area after putting, is not simple to dismantle the form or affects the finish of the concrete covering. Its principal role within the template and the concrete area to form a movie that will be separated from the two is additionally called an isolation agent.

A water-based release agent is definitely an important auxiliary within the release agent and can modify the water-based release agent circulation and levelling; its principal characteristic is actually stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based cast release agent can be used in moulds and products functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing form items aren’t just in order to let the mould release to boost productivity and prolong the life of the mould make use of. And can make the merchandise thoroughly clean, size qualified, and reduce the creation of scrap, which can be an important additional important to forms and goods – Water-based Concrete Release Agent.

Concrete release agent plays an crucial role inside modern building construction; its primary role is to create a layer of separation motion picture between the template and the concrete area so that the template does not adhere to the concrete surface so that it is much easier to take apart the form right after flowing and to maintain the complete of the concrete area. Here, we will unveil the kinds, qualities, usage and application of concrete release agent in detail.

Kinds of concrete release agent

Concrete release agents can be divided into numerous types based on different classification methods, and the frequent category methods are the subsequent:

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

Qualities of Concrete release agent

A concrete release agent is also known as a concrete separation agent or mould release lubricant. It is really a type of material coated on the inner wall of the formwork to play the function of lubrication and remoteness in order that the concrete may be smoothly detached from the formwork when dismantling the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the traditional release substance motor oil or waste motor oil, the release agent has the positive aspects of effortless release, no pollution of the concrete area, no corrosion of the template, simple to paint, low value and etc. However, not all sorts of concrete release representatives with a variety of components made of templates are suitable for different materials of the template and different building problems and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.

As an essential construction auxiliary material, concrete release agent has the next features:
Good remoteness overall performance: concrete release agent can develop a dense remoteness motion picture between the formwork and the concrete area, effectively stopping the formwork from bonding with the concrete area and facilitating the dismantling.

Great lubrication performance: concrete release agent has good lubricating performance, which can decrease the chaffing between the formwork and concrete covering, reduce the resistance during pouring and improve the construction effectiveness.

Excellent anti-adhesion performance: concrete release representatives can effectively prevent the formwork from bonding with the concrete covering, steering clear of the formwork from damaging the concrete covering when taking down the formwork.

Good waterproof efficiency: concrete release agent has good waterproof performance, which can effectively prevent 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 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 covering, tools can be used appropriately to assist in the taking apart.

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 construction 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, stopping 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 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 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 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 development projects.

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