What is actually a concrete release agent?
A concrete release agent is a substance placed on the building template before the concrete is poured in order that the design will not adhere to the concrete area right after pouring, is not easy to take apart the cast or impacts the complete of the concrete covering. Its primary role in the template and the concrete area to form a movie that will be separated from the two is also known as an remoteness agent.
A water-based release agent is definitely an important supplementary inside the release agent and can alter the water-based release agent circulation and levelling; its main feature is stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based form release agent can be used in casts and items functional processing ingredients; in the rubber, plastic, and Jinsu processing industry, manufacturing form products are not just in order to let the mould release to boost productivity and lengthen the life of the form utilize. And can make the product clean, size qualified, and reduce the creation of scrap, which can be an important supplementary important to forms and items – Water-based Concrete Release Agent.
Concrete release agent plays an important role inside modern building building; its primary role would be to develop a layer of isolation motion picture between the template and the concrete area to ensure that the template doesn’t stick to the concrete surface so that it is much easier to take apart the mould after pouring and to maintain the complete of the concrete covering. Here, we will unveil the types, features, utilization and program of concrete release agent at length.
Sorts of concrete release agent
Concrete release representatives can be divided into many sorts in accordance with different grouping strategies, and the frequent category techniques are the following:
- 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 composition of: it can be divided into water-based concrete release representatives, oil-based concrete release representatives, silicone oil concrete release agents, 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 agents and so on.
Qualities of Concrete release agent
A concrete release agent is additionally referred to as a concrete remoteness agent or mould release lubricant. It is really a sort of material coated on the inner wall of the formwork to play the function of lubricating and separation to ensure that the concrete could be effortlessly detached from the formwork when dismantling the formwork, and the condition of the concrete may be kept intact and undamaged. Compared with the conventional release substance motor oil or waste motor oil, the release agent has the positive aspects of easy release, no pollution of the concrete surface, no corrosion of the template, effortless to paint, low price and etc. However, not all kinds of concrete release representatives with a variety of materials made of templates are suitable for different supplies of the template and different development circumstances 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 following features:
Good isolation efficiency: concrete release agent can develop a dense remoteness movie between the formwork and the concrete surface, successfully stopping the formwork from bonding with the concrete covering and facilitating the removing.
Excellent lubrication performance: concrete release agent has good lubrication overall performance, which can lower the friction between the formwork and concrete area, decrease the resistance during pouring and improve the construction effectiveness.
Good anti-adhesion performance: concrete release agents can successfully stop the formwork from bonding with the concrete area, preventing the formwork from damaging the concrete covering when taking down the formwork.
Great waterproof performance: concrete release agent has good waterproof performance, which can effectively avoid moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and improving the service life of the formwork.
Effortless 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 petroleum-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 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 surface 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 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 development projects, mainly including the following aspects:
Reinforced concrete structure: In the building of a reinforced concrete structure, concrete release agents can be used for formwork isolation, preventing 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 surface and enhance 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 development projects.
In conclusion, concrete release agent, as an important construction auxiliary material, plays an indispensable role in modern development 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 building project and provide a strong guarantee for the development of the construction industry.
