What is a concrete release agent?
A concrete release agent is actually a substance applied to the development design before the concrete is poured so that the template will not adhere to the concrete surface after pouring, isn’t effortless to dismantle the mould or affects the end of the concrete area. Its main role within the template and the concrete covering to form a motion picture that will be separated from the two is additionally known as an remoteness agent.
A water-based release agent is surely an crucial supplementary inside the release agent and can alter the water-based release agent circulation and levelling; its main attribute is definitely stability to microorganisms and enzymes, which can lower the cost 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 business, manufacturing mould products aren’t just so as to let the mould release to improve productivity and lengthen the life of the form make use of. And can make the product thoroughly clean, size qualified, and lower the creation of scrap, that is an crucial supplementary essential to forms and items – concrete release agent.
Concrete release agent plays an important role in modern building construction; its primary role is to develop a layer of isolation motion picture between the template and the concrete area so that the template will not adhere to the concrete covering so that it is simpler to take down the mould following putting and to maintain the complete of the concrete surface. Here, we will present the kinds, qualities, use and application of concrete release agent in detail.
Sorts of concrete release agent
Concrete release representatives can be divided into many sorts in accordance with different category techniques, and the frequent category methods are as follows:
- 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 the composition of: it can be divided into water-based concrete release agents, oil-based concrete release representatives, silicone oil concrete release representatives, etc.
- According to the use effect: it can be divided into ordinary concrete release agents, easy-to-remove concrete release agents, high-gloss concrete release representatives and and so forth.
Qualities of Concrete release agent
A concrete release agent can also be known as a concrete remoteness agent or mould release lubricant. It is a sort of material coated on the inner wall of the formwork to play the part of lubrication and isolation to ensure that the concrete may be easily detached from the formwork when taking down the formwork, and the condition of the concrete may be kept intact and undamaged. Compared with the standard release substance 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, easy to paint, low price and so on. However, not all kinds of concrete release brokers with a variety of materials made of templates are suitable for different materials of the template and different development problems and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.
As an crucial construction auxiliary material, concrete release agent has the subsequent features:
Good isolation overall performance: concrete release agent can form a dense isolation movie between the formwork and the concrete covering, effectively stopping the formwork from bonding with the concrete area and facilitating the dismantling.
Excellent lubrication efficiency: concrete release agent has good lubrication overall performance, which can reduce the rubbing between the formwork and concrete area, reduce the resistance during pouring and enhance the construction effectiveness.
Excellent anti-adhesion efficiency: concrete release representatives can successfully stop the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete covering when taking apart the formwork.
Great waterproof efficiency: concrete release agent has good waterproof overall performance, which can successfully stop moisture from penetrating between the formwork and concrete, steering clear of 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 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 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 construction projects, mainly including the following aspects:
Reinforced concrete structure: In the building of a reinforced concrete structure, concrete release representatives 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 area 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 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 representatives 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 development 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 building industry.
