What is actually a concrete release agent?

A concrete release agent is definitely a compound placed on the building template just before the concrete is added in order that the template will not stick to the concrete surface right after pouring, is not effortless to dismantle the form or affects the complete of the concrete area. Its main role in the template and the concrete area to form a film that will be separated from the two is also known as an isolation agent.

A water-based release agent is definitely an important ancillary within the release agent and can modify the water-based release agent circulation and levelling; its principal characteristic is stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based form release agent can be used in forms and items functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing form goods are not just in order to let the form release to improve productivity and prolong the life of the cast make use of. And can make the product clear, size qualified, and reduce the creation of scrap, that is an crucial additive important to forms and items – Water-based Concrete Release Agent.

Concrete release agent plays an essential role inside modern building development; its principal role would be to develop a layer of separation movie between the template and the concrete covering so that the template does not stick to to the concrete covering to ensure that it is simpler to dismantle the cast following flowing and to maintain the finish of the concrete surface. Here, we will introduce the kinds, features, use and use of concrete release agent in more detail.

Types of concrete release agent

Concrete release brokers can be divided into several kinds based on different grouping strategies, and the common grouping methods are as follows:

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

Features of Concrete release agent

A concrete release agent can also be known as a concrete separation agent or mould release lubricant. It is really a kind of material coated on the inner wall of the formwork to play the function of lubricating and isolation to ensure that the concrete could be easily detached from the formwork when dismantling the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the standard release substance motor oil or waste motor oil, the release agent has the advantages of effortless release, no pollution of the concrete covering, no corrosion of the template, easy to paint, low price and and so forth. However, not all types of concrete release brokers with a selection of supplies made of templates are suitable for different components of the template and different development 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 qualities:
Good remoteness performance: concrete release agent can create a dense isolation movie between the formwork and the concrete covering, successfully stopping the formwork from bonding with the concrete covering and facilitating the demolding.

Excellent lubrication overall performance: concrete release agent has good lubrication efficiency, which can decrease the rubbing between the formwork and concrete surface, decrease the resistance during pouring and boost the construction productivity.

Great anti-adhesion overall performance: concrete release agents can efficiently avoid the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete area when dismantling the formwork.

Excellent waterproof overall performance: concrete release agent has good waterproof overall performance, which can efficiently 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 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 surface.

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 surface gradually. In case of tight bonding between the formwork and the concrete surface, tools can be used appropriately to assist in the taking apart.

Clean up the template: after dismantling 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 development of a reinforced concrete structure, concrete release brokers can be used for formwork isolation, avoiding 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 surface, 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 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 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 brokers 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 essential 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 boost the construction efficiency and quality of the building project and provide a strong guarantee for the growth of the development industry.
