What is actually a concrete release agent?
A concrete release agent is definitely a material applied to the development design just before the concrete is poured in order that the template will not stick to the concrete surface after putting, is just not simple to take apart the mould or influences the end of the concrete area. Its principal role within the template and the concrete area to form a movie that is going to be separated from the two is also called an isolation agent.
A water-based release agent is definitely an important supplementary in the release agent and can change the water-based release agent flow and levelling; its principal attribute is actually stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based form release agent is used in casts and items functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing mould goods are not only so as to let the form release to enhance productivity and prolong the life of the form make use of. And can make the product thoroughly clean, size qualified, and reduce the technology of scrap, which can be an important supplementary essential to casts and goods – concrete release agent.
Concrete release agent plays an crucial role inside modern building development; its principal role would be to form a layer of separation movie between the template and the concrete area in order that the template does not stick to to the concrete area to ensure that it is simpler to dismantle the form right after putting and to maintain the complete of the concrete surface. Here, we will introduce the kinds, characteristics, use and application of concrete release agent at length.
Kinds of concrete release agent
Concrete release representatives can be divided into numerous types based on different classification methods, and the typical grouping strategies are the following:
- According to the the scope of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete emission agent for tunnels and and so forth.
- According to the composition: it can be divided into water-based concrete release agents, petroleum-based concrete release representatives, silicone oil concrete release representatives, etc.
- According to the utilization effect: it can be divided into ordinary concrete release agents, easy-to-remove concrete release representatives, high-gloss concrete release representatives and and so forth.
Qualities of Concrete release agent
A concrete release agent is also known as a concrete remoteness agent or mould release lubricant. It is a sort of compound coated on the inner wall of the formwork to play the function of lubricating and separation in order that the concrete could be smoothly 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 materials motor oil or waste motor oil, the release agent has the advantages of simple release, no pollution of the concrete surface, no corrosion of the template, effortless to paint, low cost and and so forth. However, not all types of concrete release brokers with a array of supplies made of templates are suitable for different components of the template and different building problems and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.
As an essential construction auxiliary material, concrete release agent has the following characteristics:
Good separation efficiency: concrete release agent can form a dense separation motion picture between the formwork and the concrete area, successfully avoiding the formwork from bonding with the concrete surface and facilitating the demolding.
Great lubrication efficiency: concrete release agent has good lubricating performance, which can lower the rubbing between the formwork and concrete area, decrease the resistance during pouring and boost the construction efficiency.
Good anti-adhesion efficiency: concrete release representatives can successfully prevent the formwork from bonding with the concrete covering, steering clear of the formwork from damaging the concrete surface when taking apart the formwork.
Great waterproof efficiency: concrete release agent has good waterproof performance, which can efficiently avoid moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and improving 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 surface.
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 dismantling.
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 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 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 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 improve 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 construction projects.
In conclusion, concrete release agent, as an crucial 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 improve the construction efficiency and quality of the development project and provide a strong guarantee for the development of the development industry.
