What is actually a concrete release agent?
A concrete release agent is a substance placed on the construction template just before the concrete is put so that the template doesn’t stick to to the concrete covering right after putting, is just not easy to dismantle the cast or influences the complete of the concrete surface. Its primary role within the design and the concrete covering to develop a film that will be separated from the two can also be referred to as an isolation agent.
A water-based release agent is surely an essential auxiliary inside the release agent and can alter the water-based release agent flow and levelling; its principal feature is actually stability to microorganisms and enzymes, which can decrease the price 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 business, manufacturing form goods aren’t just to be able to let the mould release to boost productivity and lengthen the life of the cast utilize. And can make the product thoroughly clean, size qualified, and decrease the generation of scrap, that is an important supplementary vital to forms and items – concrete additive.
Concrete release agent plays an important role within modern building construction; its primary role is always to create a layer of remoteness film between the design and the concrete surface in order that the template doesn’t stick to the concrete surface to ensure that it is much easier to take down the mould right after putting and to maintain the end of the concrete area. Here, we will present the kinds, features, utilization and application of concrete release agent in detail.
Types of concrete release agent
Concrete release representatives can be divided into many sorts in accordance with different grouping methods, and the typical category strategies are the subsequent:
- According to the opportunity of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete emission agent for tunnels and and so forth.
- According to the the composition of: it can be divided into water-based concrete release brokers, oil-based concrete release brokers, silicone oil concrete release agents, etc.
- According to the the utilization effect: it can be divided into ordinary concrete release brokers, an easy task to remove concrete release agents, high-gloss concrete release agents and etc.
Characteristics of Concrete release agent
A concrete release agent is additionally called a concrete separation agent or mould release lubricant. It is a kind of material coated on the inner wall of the formwork to play the role of lubrication and separation to ensure that the concrete can be effortlessly detached from the formwork when dismantling the formwork, and the form of the concrete may be kept intact and undamaged. Compared with the conventional release material motor oil or waste motor oil, the release agent has the advantages of simple release, no pollution of the concrete covering, no corrosion of the template, easy to paint, low value and so on. However, not all kinds of concrete release agents with a variety of components made of templates are suitable for different components of the template and different construction conditions 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 next characteristics:
Good separation overall performance: concrete release agent can develop a dense isolation movie between the formwork and the concrete surface, effectively stopping the formwork from bonding with the concrete surface and facilitating the removing.
Good lubrication overall performance: concrete release agent has good lubricating performance, which can reduce the rubbing between the formwork and concrete covering, lower the resistance during pouring and boost the construction productivity.
Good anti-adhesion efficiency: concrete release brokers can efficiently prevent the formwork from bonding with the concrete surface, avoiding the formwork from damaging the concrete area when dismantling the formwork.
Good waterproof efficiency: concrete release agent has good waterproof overall performance, which can effectively prevent moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and improving the service life of the formwork.
Simple 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 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 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 covering, tools can be used appropriately to assist in the taking apart.
Clean up the template: after taking apart 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 construction 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 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 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 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 construction 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 construction project and provide a strong guarantee for the development of the construction industry.
