What is a concrete release agent?
A concrete release agent is actually a material placed on the construction design prior to the concrete is added so the design does not stick to the concrete surface right after putting, is just not effortless to dismantle the cast or affects the end of the concrete covering. Its main role within the design and the concrete surface to develop a movie that will be separated from the two is additionally known as an remoteness agent.
A water-based release agent is an essential supplementary within the release agent and can alter the water-based release agent flow and levelling; its principal characteristic is stability to microorganisms and enzymes, which can decrease the cost of raw materials. A water-based form release agent can be used in moulds and products functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing mould products are not only so as to let the form release to enhance productivity and prolong the life of the cast utilize. And can make the item clean, size qualified, and reduce the creation of scrap, which is an important additive essential to casts and items – concrete additive.
Concrete release agent plays an essential role in modern building building; its main role is always to form a layer of remoteness film between the design and the concrete surface to ensure that the template doesn’t stick to the concrete surface in order that it is easier to take down the mould following putting and to maintain the end of the concrete surface. Here, we will introduce the sorts, features, usage and application of concrete release agent at length.
Sorts of concrete release agent
Concrete release agents can be divided into several kinds according to different grouping techniques, and the common grouping strategies are the subsequent:
- 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 so on.
- According to the the composition: it can be divided into water-based concrete release brokers, petroleum-based concrete release agents, silicone oil concrete release representatives, etc.
- According to the the effect of use: it can be divided into ordinary concrete release representatives, an easy task to remove concrete release representatives, high-gloss concrete release brokers and so on.
Qualities of Concrete release agent
A concrete release agent is additionally called a concrete separation agent or mould release lubricant. It is a type of material coated on the inner wall of the formwork to play the role of lubrication and isolation in order that the concrete can be smoothly detached from the formwork when taking apart the formwork, and the shape of the concrete may be kept intact and undamaged. Compared with the standard release materials motor oil or waste motor oil, the release agent has the benefits of effortless release, no pollution of the concrete area, no corrosion of the template, easy to paint, low value and and so forth. However, not all types of concrete release agents with a variety of materials made of templates are suitable for different supplies of the template and different building problems and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.
As an important construction auxiliary material, concrete release agent has the subsequent characteristics:
Good separation overall performance: 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 covering and facilitating the removing.
Great lubrication overall performance: concrete release agent has good lubrication overall performance, which can reduce the chaffing between the formwork and concrete covering, decrease the resistance during pouring and enhance the construction productivity.
Great anti-adhesion efficiency: concrete release brokers can successfully prevent the formwork from bonding with the concrete covering, avoiding the formwork from damaging the concrete surface when taking apart the formwork.
Great waterproof performance: concrete release agent has good waterproof overall performance, which can successfully prevent 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.
Simple to use and safe: concrete release agent is simple 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 area.
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 area gradually. In case of tight bonding between the formwork and the concrete surface, tools can be used appropriately to assist in the taking down.
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 construction of a reinforced concrete structure, concrete release brokers can be used for formwork isolation, avoiding 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 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 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 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 essential construction auxiliary material, plays an indispensable role in modern building projects. By choosing the right type, the correct use method and a reasonable application field, can effectively enhance the construction efficiency and quality of the building project and provide a strong guarantee for the growth of the development industry.
