What exactly is a concrete release agent?
A concrete release agent is actually a substance applied to the development template just before the concrete is added in order that the design does not stick to the concrete surface right after flowing, is not simple to dismantle the form or impacts the complete of the concrete area. Its main role inside the design and the concrete covering to form a movie that will be separated from the two is also referred to as an separation agent.
A water-based release agent is surely an essential auxiliary in the release agent and can modify the water-based release agent stream and levelling; its principal characteristic is actually stability to microorganisms and enzymes, which can reduce the expense of raw materials. A water-based mould release agent is used in casts and products functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing mould items are not only in order to let the form release to enhance productivity and lengthen the life of the cast use. And can make the item clear, size qualified, and lower the generation of scrap, that is an essential supplementary important to moulds and products – Water-based Concrete Release Agent.
Concrete release agent plays an crucial role within modern building building; its primary role is to develop a layer of separation motion picture 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 form following putting and to maintain the finish of the concrete surface. Here, we will unveil the kinds, qualities, utilization and program of concrete release agent in more detail.
Sorts of concrete release agent
Concrete release brokers can be divided into numerous types based on different category techniques, and the common classification strategies are the subsequent:
- According to the the opportunity of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete release agent for tunnels and etc.
- According to the composition: it can be divided into water-based concrete release brokers, oil-based concrete release brokers, silicone oil concrete release agents, etc.
- According to the the effect of use: it can be divided into ordinary concrete release brokers, simple to remove concrete release representatives, high-gloss concrete release representatives and etc.
Qualities of Concrete release agent
A concrete release agent is additionally called a concrete separation agent or mould release lubricant. It is a type of material coated on the inner wall of the formwork to play the role of lubrication and separation so that the concrete may be effortlessly detached from the formwork when taking down the formwork, and the form of the concrete can be kept intact and undamaged. Compared with the conventional release materials 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 value and etc. However, not all types of concrete release agents with a array of materials made of templates are suitable for different components of the template and different development circumstances and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.
As an important construction auxiliary material, concrete release agent has the following characteristics:
Good separation overall performance: concrete release agent can create a dense isolation movie between the formwork and the concrete covering, effectively avoiding the formwork from bonding with the concrete covering and facilitating the removing.
Excellent lubrication overall performance: concrete release agent has good lubricating performance, which can decrease the friction between the formwork and concrete covering, lower the resistance during pouring and enhance the construction productivity.
Great anti-adhesion overall performance: concrete release representatives can effectively stop the formwork from bonding with the concrete covering, preventing the formwork from damaging the concrete covering when dismantling the formwork.
Good waterproof performance: concrete release agent has good waterproof overall performance, which can successfully avoid moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and increasing the service life of the formwork.
Simple 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 covering.
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 surface 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 dismantling.
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, 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 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 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 building projects.
In conclusion, concrete release agent, as an crucial construction auxiliary material, plays an indispensable role in modern building projects. By choosing the right kind, the correct use method and a reasonable application field, can effectively improve the construction efficiency and quality of the building project and provide a strong guarantee for the growth of the building industry.
