What exactly is a concrete release agent?
A concrete release agent is definitely a material applied to the building template prior to the concrete is put in order that the design doesn’t stick to to the concrete covering following flowing, isn’t effortless to dismantle the cast or influences the finish of the concrete covering. Its main role in the design and the concrete covering to form a movie that will be separated from the two can also be known as an isolation agent.
A water-based release agent is an crucial ancillary within the release agent and can modify the water-based release agent circulation and levelling; its main characteristic is actually stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based cast release agent is used in casts and products functional processing additives; in the rubber, plastic, and Jinsu processing business, manufacturing cast products are not only in order to let the mould release to boost productivity and lengthen the life of the mould make use of. And can make the merchandise clean, size qualified, and decrease the creation of scrap, which can be an important additional essential to casts and products – concrete release agent.
Concrete release agent plays an crucial role inside modern building building; its primary role would be to form a layer of remoteness movie between the template and the concrete area to ensure that the template doesn’t adhere to the concrete surface in order that it is simpler to take apart the mould following pouring and to maintain the complete of the concrete area. Here, we will unveil the kinds, features, usage and program of concrete release agent in more detail.
Types of concrete release agent
Concrete release representatives can be divided into numerous sorts in accordance with different classification techniques, and the common category methods are as follows:
- According to the the opportunity of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete discharge agent for tunnels and etc.
- According to the formula of: it can be divided into water-based concrete release brokers, petroleum-based concrete release brokers, silicone oil concrete release representatives, etc.
- According to the the utilization effect: it can be divided into ordinary concrete release agents, an easy task to remove concrete release brokers, high-gloss concrete release representatives and so on.
Qualities of Concrete release agent
A concrete release agent can also be referred to as a concrete remoteness agent or mould release lubricant. It is really a sort of compound coated on the inner wall of the formwork to play the function of lubricating and isolation to ensure that the concrete could be effortlessly detached from the formwork when taking apart the formwork, and the shape of the concrete may be kept intact and undamaged. Compared with the conventional release materials motor oil or waste motor oil, the release agent has the benefits of simple release, no pollution of the concrete area, no corrosion of the template, effortless to paint, low value and and so forth. However, not all sorts of concrete release agents with a array 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 crucial construction auxiliary material, concrete release agent has the next qualities:
Good remoteness performance: concrete release agent can develop a dense remoteness film between the formwork and the concrete surface, effectively preventing the formwork from bonding with the concrete covering and facilitating the demolding.
Excellent lubrication efficiency: concrete release agent has good lubricating overall performance, which can decrease the chaffing between the formwork and concrete surface, lower the resistance during pouring and improve the construction productivity.
Good anti-adhesion efficiency: concrete release agents can efficiently prevent the formwork from bonding with the concrete covering, avoiding the formwork from damaging the concrete area when taking apart the formwork.
Excellent waterproof overall performance: concrete release agent has good waterproof performance, which can effectively prevent moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and increasing the service life of the formwork.
Easy 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 surface.
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 surface gradually. In case of tight bonding between the formwork and the concrete area, tools can be used appropriately to assist in the taking apart.
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 development projects, mainly including the following aspects:
Reinforced concrete structure: In the building 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 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 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 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 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 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 enhance the construction efficiency and quality of the development project and provide a strong guarantee for the development of the development industry.
