Examining the Effects of Concrete Additives on Fire Resistance

What exactly is a concrete release agent?

A concrete release agent is a compound put on the construction template prior to the concrete is poured in order that the design will not adhere to the concrete covering following flowing, is not easy to dismantle the form or affects the complete of the concrete covering. Its primary role within the template and the concrete surface to create a movie that will probably be separated from the two is additionally called an isolation agent.

A water-based release agent is surely an important auxiliary inside the release agent and can alter the water-based release agent stream and levelling; its principal feature is actually stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based mould release agent is utilized in moulds and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing market, manufacturing cast goods are not only to be able to let the cast release to boost productivity and lengthen the life of the form use. And can make the product thoroughly clean, size qualified, and lower the generation of scrap, that is an crucial supplementary vital to forms and goods – Water-based Concrete Release Agent.

Concrete release agent plays an essential role in modern building construction; its main role is to develop a layer of separation motion picture between the template and the concrete covering so that the template does not adhere to the concrete area to ensure that it is much easier to take apart the form following putting and to maintain the complete of the concrete surface. Here, we will unveil the sorts, qualities, utilization and use of concrete release agent in detail.

Types of concrete release agent

Concrete release representatives can be divided into several sorts based on different grouping strategies, and the frequent grouping methods are the subsequent:

  • According to the the opportunity of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete release agent for tunnels and so on.
  • According to the composition 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 effect of use: it can be divided into ordinary concrete release brokers, simple to remove concrete release brokers, high-gloss concrete release brokers and so on.

Features of Concrete release agent

A concrete release agent can also be referred to as a concrete remoteness agent or mould release lubricant. It is really a type of substance coated on the inner wall of the formwork to play the role of lubricating and separation in order that the concrete could be smoothly detached from the formwork when taking apart the formwork, and the shape of the concrete can be kept intact and undamaged. Compared with the standard release materials 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 kinds of concrete release agents with a variety of materials made of templates are suitable for different components 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 important construction auxiliary material, concrete release agent has the next features:
Good separation efficiency: concrete release agent can create a dense isolation film between the formwork and the concrete surface, efficiently stopping the formwork from bonding with the concrete covering and facilitating the removing.

Excellent lubrication efficiency: concrete release agent has good lubricating performance, which can lower the friction between the formwork and concrete surface, lower the resistance during pouring and improve the construction efficiency.

Great anti-adhesion overall performance: concrete release representatives can successfully avoid the formwork from bonding with the concrete area, preventing the formwork from damaging the concrete area when taking down the formwork.

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

Effortless 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 area.

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 covering of the formwork should be knocked gently to separate the formwork from the concrete covering 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 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 development 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, preventing 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 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 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 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 construction projects.

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