What is actually a concrete release agent?
A concrete release agent is definitely a material put on the development template just before the concrete is poured so that the design will not adhere to the concrete surface following putting, isn’t simple to dismantle the form or impacts the complete of the concrete covering. Its principal role in the template and the concrete surface to develop a movie that will be separated from the two can also be known as an remoteness agent.
A water-based release agent is definitely an crucial ancillary within the release agent and can change the water-based release agent flow and levelling; its principal attribute is actually stability to microorganisms and enzymes, which can decrease the cost of raw materials. A water-based mould release agent is utilized in forms and goods functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing mould items are not just in order to let the form release to improve productivity and prolong the life of the form use. And can make the product clear, size qualified, and decrease the creation of scrap, which can be an important additive essential to forms and goods – concrete release agent.
Concrete release agent plays an crucial role within modern building construction; its primary role is always to form a layer of remoteness motion picture between the template and the concrete surface in order that the design does not adhere to the concrete surface in order that it is easier to dismantle the mould after pouring and to maintain the complete of the concrete area. Here, we will introduce the kinds, qualities, use and use of concrete release agent in more detail.
Sorts of concrete release agent
Concrete release brokers can be divided into numerous kinds according to different category strategies, and the typical grouping strategies are the following:
- According to the the scope of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete release agent for tunnels and and so forth.
- According to the the composition of: it can be divided into water-based concrete release representatives, oil-based concrete release brokers, silicone oil concrete release brokers, etc.
- According to the use effect: it can be divided into ordinary concrete release agents, simple to remove concrete release brokers, high-gloss concrete release brokers and etc.
Qualities of Concrete release agent
A concrete release agent is additionally referred to as a concrete remoteness agent or mould release lubricant. It is really a type of compound coated on the inner wall of the formwork to play the role of lubricating and isolation so that the concrete can be easily detached from the formwork when dismantling 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 advantages of simple release, no pollution of the concrete area, no corrosion of the template, simple to paint, low cost and and so forth. However, not all types of concrete release representatives with a variety of supplies made of templates are suitable for different supplies of the template and different construction conditions 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 separation performance: concrete release agent can develop a dense isolation film between the formwork and the concrete covering, successfully preventing the formwork from bonding with the concrete area and facilitating the removing.
Great lubrication overall performance: concrete release agent has good lubricating overall performance, which can reduce the rubbing between the formwork and concrete covering, decrease the resistance during pouring and enhance the construction productivity.
Great anti-adhesion efficiency: concrete release representatives can successfully avoid the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete area when dismantling the formwork.
Good waterproof performance: concrete release agent has good waterproof overall performance, which can efficiently stop moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and enhancing 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 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 area gradually. In case of tight bonding between the formwork and the concrete area, 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, 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 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 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 development projects.
In conclusion, concrete release agent, as an essential 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 improve the construction efficiency and quality of the building project and provide a strong guarantee for the growth of the construction industry.
