What is a concrete release agent?
A concrete release agent is definitely a substance applied to the construction template before the concrete is added so the template does not adhere to the concrete covering following flowing, is just not simple to take down the form or impacts the finish of the concrete covering. Its principal role inside the template and the concrete area to create a movie that will be separated from the two is additionally called an separation agent.
A water-based release agent is definitely an important supplementary inside the release agent and can change the water-based release agent stream and levelling; its principal characteristic is actually stability to microorganisms and enzymes, which can reduce the expense of raw materials. A water-based cast release agent can be used in casts and goods functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing cast goods are not just to be able to let the cast release to enhance productivity and lengthen the life of the mould use. And can make the item thoroughly clean, size qualified, and decrease the creation of scrap, which is an essential additional essential to moulds and items – Water-based Concrete Release Agent.
Concrete release agent plays an crucial role in modern building construction; its principal role is to develop a layer of isolation movie between the design and the concrete covering so that the design does not adhere to the concrete area in order that it is easier to dismantle the mould after pouring and to maintain the complete of the concrete surface. Here, we will introduce the kinds, qualities, utilization and use of concrete release agent at length.
Sorts of concrete release agent
Concrete release representatives can be divided into many types in accordance with different grouping techniques, and the typical grouping methods are as follows:
- According to the scope of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete emission agent for tunnels and so on.
- According to the composition: it can be divided into water-based concrete release agents, petroleum-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 agents, high-gloss concrete release brokers and etc.
Characteristics of Concrete release agent
A concrete release agent is also referred to as a concrete remoteness agent or mould release lubricant. It is actually a type of substance coated on the inner wall of the formwork to play the function of lubrication and isolation in order that the concrete may be effortlessly detached from the formwork when taking apart the formwork, and the condition of the concrete can be kept intact and undamaged. Compared with the conventional release materials motor oil or waste motor oil, the release agent has the advantages of easy release, no pollution of the concrete area, no corrosion of the template, easy to paint, low value and etc. However, not all kinds of concrete release brokers with a selection of materials made of templates are suitable for different supplies 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 essential construction auxiliary material, concrete release agent has the subsequent characteristics:
Good separation overall performance: concrete release agent can create a dense isolation movie between the formwork and the concrete surface, successfully preventing the formwork from bonding with the concrete surface and facilitating the dismantling.
Good lubrication efficiency: concrete release agent has good lubrication performance, which can decrease the friction between the formwork and concrete area, lower the resistance during pouring and boost the construction effectiveness.
Great anti-adhesion efficiency: concrete release representatives can efficiently prevent the formwork from bonding with the concrete covering, avoiding the formwork from damaging the concrete covering when taking apart the formwork.
Great waterproof performance: concrete release agent has good waterproof performance, which can efficiently stop moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and enhancing 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 surface.
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 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 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 construction 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 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 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 building projects.
In conclusion, concrete release agent, as an crucial 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 enhance the construction efficiency and quality of the construction project and provide a strong guarantee for the development of the construction industry.
