What exactly is a concrete release agent?
A concrete release agent is a substance placed on the development design before the concrete is added in order that the template does not stick to the concrete area after putting, is not easy to dismantle the mould or impacts the end of the concrete covering. Its main role in the template and the concrete area to develop a movie that will be separated from the two is also known as an separation agent.
A water-based release agent is definitely an important auxiliary within the release agent and can alter the water-based release agent flow and levelling; its primary feature is actually stability to microorganisms and enzymes, which can decrease the cost of raw materials. A water-based mould release agent can be used in forms and products functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing mould products are not just in order to let the mould release to enhance productivity and prolong the life of the cast make use of. And can make the item clear, size qualified, and lower the technology of scrap, which is an important additional important to casts and items – concrete additive.
Concrete release agent plays an crucial role inside modern building building; its primary role would be to form a layer of remoteness movie between the design and the concrete covering in order that the design will not stick to the concrete area in order that it is easier to dismantle the form after pouring and to maintain the complete of the concrete covering. Here, we will unveil the types, characteristics, use and program of concrete release agent at length.
Sorts of concrete release agent
Concrete release representatives can be divided into several types according to different classification methods, and the typical classification methods are the following:
- According to 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 formula of: it can be divided into water-based concrete release agents, petroleum-based concrete release brokers, silicone oil concrete release brokers, etc.
- According to the effect of use: it can be divided into ordinary concrete release brokers, an easy task to remove concrete release brokers, high-gloss concrete release representatives and so on.
Qualities of Concrete release agent
A concrete release agent is additionally known as a concrete remoteness agent or mould release lubricant. It is actually a sort of material coated on the inner wall of the formwork to play the role of lubricating and remoteness to ensure that the concrete may be smoothly detached from the formwork when taking down the formwork, and the form of the concrete may be kept intact and undamaged. Compared with the traditional release material motor oil or waste motor oil, the release agent has the positive aspects of effortless release, no pollution of the concrete covering, no corrosion of the template, effortless to paint, low cost and and so forth. However, not all sorts of concrete release agents with a variety of components 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 appropriate release agent in order to receive good results.
As an essential construction auxiliary material, concrete release agent has the next qualities:
Good remoteness overall performance: concrete release agent can create a dense remoteness motion picture between the formwork and the concrete area, successfully 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, decrease the resistance during pouring and boost the construction productivity.
Great anti-adhesion efficiency: concrete release representatives can efficiently stop the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete area when taking apart the formwork.
Great waterproof performance: concrete release agent has good waterproof performance, which can successfully avoid 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 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 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 covering gradually. In case of tight bonding between the formwork and the concrete covering, 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 construction of a reinforced concrete structure, concrete release brokers can be used for formwork isolation, preventing 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 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 boost 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 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 kind, the correct use method and a reasonable application field, can effectively improve the construction efficiency and quality of the construction project and provide a strong guarantee for the growth of the building industry.
