What is actually a concrete release agent?
A concrete release agent is actually a substance placed on the development template before the concrete is poured so that the template will not stick to the concrete covering following pouring, is not easy to take apart the form or affects the finish of the concrete surface. Its principal role within the design and the concrete area to create a film that will probably be separated from the two is additionally called an separation agent.
A water-based release agent is an essential ancillary inside the release agent and can change the water-based release agent flow and levelling; its main characteristic is actually stability to microorganisms and enzymes, which can lower the cost of raw materials. A water-based mould release agent is used in moulds and goods functional processing supplements; in the rubber, plastic, and Jinsu processing market, manufacturing cast goods are not only to be able to let the cast release to enhance productivity and lengthen the life of the form use. And can make the item thoroughly clean, size qualified, and lower the technology of scrap, that is an essential supplementary important to moulds and items – concrete release agent.
Concrete release agent plays an crucial role within modern building building; its main role is always to form a layer of separation movie between the template and the concrete surface so that the template will not stick to to the concrete surface in order that it is easier to take apart the form after putting and to maintain the end of the concrete covering. Here, we will present the kinds, features, use and use of concrete release agent at length.
Sorts of concrete release agent
Concrete release agents can be divided into numerous types in accordance with different classification methods, and the typical category strategies are the following:
- According to the opportunity of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete emission agent for tunnels and and so forth.
- According to the composition of: it can be divided into water-based concrete release brokers, oil-based concrete release agents, silicone oil concrete release representatives, etc.
- According to the effect of use: it can be divided into ordinary concrete release representatives, simple to remove concrete release brokers, high-gloss concrete release representatives and so on.
Features of Concrete release agent
A concrete release agent is also called a concrete remoteness agent or mould release lubricant. It is really a sort of substance coated on the inner wall of the formwork to play the role of lubricating and remoteness 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 traditional release material motor oil or waste motor oil, the release agent has the advantages of easy release, no pollution of the concrete surface, no corrosion of the template, simple to paint, low value and so on. However, not all sorts of concrete release brokers with a selection of supplies made of templates are suitable for different components of the template and different construction 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 characteristics:
Good separation overall performance: concrete release agent can form a dense separation motion picture between the formwork and the concrete area, effectively preventing the formwork from bonding with the concrete surface and facilitating the removing.
Excellent lubrication overall performance: concrete release agent has good lubricating performance, which can decrease the chaffing between the formwork and concrete area, reduce the resistance during pouring and boost the construction productivity.
Good anti-adhesion efficiency: concrete release brokers can successfully stop the formwork from bonding with the concrete covering, preventing the formwork from damaging the concrete covering when taking down the formwork.
Great waterproof performance: concrete release agent has good waterproof overall performance, which can effectively stop moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and increasing the service life of the formwork.
Simple 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 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 covering gradually. In case of tight bonding between the formwork and the concrete surface, 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 building projects, mainly including the following aspects:
Reinforced concrete structure: In the development of a reinforced concrete structure, concrete release agents 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 area, 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 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 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 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 construction projects.
In conclusion, concrete release agent, as an important construction auxiliary material, plays an indispensable role in modern construction projects. By choosing the right kind, the correct use method and a reasonable application field, can effectively boost the construction efficiency and quality of the building project and provide a strong guarantee for the development of the construction industry.
