What is actually a concrete release agent?
A concrete release agent is a substance applied to the development template before the concrete is put so the template does not stick to the concrete covering following putting, is just not simple to take down the mould or influences the finish of the concrete area. Its principal role inside the design and the concrete covering to create a motion picture that will probably be separated from the two is additionally called an separation agent.
A water-based release agent is definitely an crucial auxiliary inside the release agent and can modify the water-based release agent flow and levelling; its main characteristic is actually stability to microorganisms and enzymes, which can decrease the price of raw materials. A water-based cast release agent is used in moulds and goods functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing mould products aren’t just to be able to let the cast release to enhance productivity and lengthen the life of the mould use. And can make the merchandise thoroughly clean, size qualified, and lower the creation of scrap, which can be an important additive essential to moulds and goods – concrete additive.
Concrete release agent plays an crucial role inside modern building development; its principal role would be to form a layer of separation film between the design and the concrete area in order that the template doesn’t stick to to the concrete area to ensure that it is simpler to take apart the cast following putting and to maintain the complete of the concrete area. Here, we will unveil the kinds, characteristics, utilization and application of concrete release agent in detail.
Kinds of concrete release agent
Concrete release representatives can be divided into several types according to different category techniques, and the common grouping methods are the following:
- According to the scope of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete launch agent for tunnels and etc.
- According to the composition of: it can be divided into water-based concrete release representatives, oil-based concrete release agents, silicone oil concrete release agents, etc.
- According to the utilization effect: it can be divided into ordinary concrete release representatives, simple to remove concrete release agents, high-gloss concrete release agents and and so forth.
Characteristics of Concrete release agent
A concrete release agent is additionally called a concrete isolation agent or mould release lubricant. It is actually a type of material coated on the inner wall of the formwork to play the part of lubrication and separation so that the concrete can 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 conventional release substance 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, easy to paint, low value and so on. However, not all kinds of concrete release brokers with a selection of components made of templates are suitable for different materials of the template and different construction problems and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.
As an crucial construction auxiliary material, concrete release agent has the following qualities:
Good separation overall performance: concrete release agent can develop a dense isolation motion picture between the formwork and the concrete area, successfully preventing the formwork from bonding with the concrete area and facilitating the dismantling.
Excellent lubrication overall performance: concrete release agent has good lubrication overall performance, which can reduce the rubbing between the formwork and concrete surface, reduce the resistance during pouring and enhance the construction efficiency.
Great anti-adhesion efficiency: concrete release representatives can effectively avoid the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete surface when taking down the formwork.
Excellent waterproof efficiency: concrete release agent has good waterproof overall performance, which can effectively prevent moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and enhancing the service life of the formwork.
Easy to use and safe: concrete release agent is easy 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 taking apart 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 surface, tools can be used appropriately to assist in the taking down.
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 building projects, mainly including the following aspects:
Reinforced concrete structure: In the building of a reinforced concrete structure, concrete release brokers can be used for formwork isolation, stopping 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 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 area 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 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 building projects.
In conclusion, concrete release agent, as an important construction auxiliary material, plays an indispensable role in modern building 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 construction project and provide a strong guarantee for the growth of the development industry.
