What is a concrete release agent?
A concrete release agent is definitely a material placed on the building design before the concrete is put in order that the design does not adhere to the concrete covering right after putting, is just not simple to take apart the cast or affects the end of the concrete covering. Its primary role within the design and the concrete covering to create a movie that will probably be separated from the two can also be known as an separation agent.
A water-based release agent is an important ancillary inside the release agent and can alter the water-based release agent flow and levelling; its primary attribute is actually stability to microorganisms and enzymes, which can decrease the expense of raw materials. A water-based mould release agent can be used in moulds and products functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing cast items aren’t just so as to let the mould release to improve productivity and prolong the life of the cast use. And can make the product clean, size qualified, and reduce the generation of scrap, that is an important additional important to forms and items – concrete additive.
Concrete release agent plays an crucial role within modern building construction; its main role is always to create a layer of remoteness film between the template and the concrete surface so that the design doesn’t stick to to the concrete area in order that it is much easier to dismantle the cast right after pouring and to maintain the complete of the concrete surface. Here, we will introduce the kinds, features, utilization and program of concrete release agent in detail.
Types of concrete release agent
Concrete release agents can be divided into numerous types according to different category techniques, and the typical classification techniques are as follows:
- According to the the scope of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete release agent for tunnels and etc.
- According to the the formula of: it can be divided into water-based concrete release brokers, oil-based concrete release agents, silicone oil concrete release agents, etc.
- According to the the utilization effect: it can be divided into ordinary concrete release agents, simple to remove concrete release brokers, high-gloss concrete release brokers and so on.
Features of Concrete release agent
A concrete release agent is additionally known as a concrete separation agent or mould release lubricant. It is actually a sort of compound coated on the inner wall of the formwork to play the function of lubricating and isolation so that the concrete could be smoothly detached from the formwork when dismantling the formwork, and the form of the concrete could 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 price and etc. However, not all types of concrete release brokers with a array of materials made of templates are suitable for different components of the template and different development conditions and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.
As an important construction auxiliary material, concrete release agent has the subsequent qualities:
Good remoteness efficiency: concrete release agent can form a dense isolation film between the formwork and the concrete surface, efficiently avoiding the formwork from bonding with the concrete covering and facilitating the dismantling.
Excellent lubrication performance: concrete release agent has good lubricating efficiency, which can decrease the friction between the formwork and concrete surface, decrease the resistance during pouring and enhance the construction efficiency.
Good anti-adhesion overall performance: concrete release representatives can efficiently stop the formwork from bonding with the concrete surface, steering clear of the formwork from damaging the concrete area when taking down the formwork.
Good waterproof overall performance: concrete release agent has good waterproof performance, which can successfully 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 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 area 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 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 construction projects, mainly including the following aspects:
Reinforced concrete structure: In the development of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, avoiding 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 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 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 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 agents 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 development 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 growth of the development industry.
