What is a concrete release agent?
A concrete release agent is actually a compound placed on the development design prior to the concrete is added so that the template will not adhere to the concrete covering right after flowing, isn’t simple to dismantle the form or affects the complete of the concrete area. Its principal role within the template and the concrete surface to create a movie that will be separated from the two is also called an isolation agent.
A water-based release agent is surely an important auxiliary in the release agent and can change the water-based release agent circulation and levelling; its primary attribute is actually stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based mould release agent is used in casts and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing market, manufacturing mould items aren’t just so as to let the mould release to enhance productivity and extend the life of the mould make use of. And can make the merchandise thoroughly clean, size qualified, and decrease the generation of scrap, that is an essential additive vital to forms and items – Water-based Concrete Release Agent.
Concrete release agent plays an crucial role inside modern building building; its principal role is always to create a layer of separation film between the template and the concrete covering to ensure that the template doesn’t adhere to the concrete covering in order that it is much easier to take down the cast following putting and to maintain the end of the concrete surface. Here, we will present the sorts, characteristics, utilization and use of concrete release agent at length.
Types of concrete release agent
Concrete release brokers can be divided into several types according to different grouping strategies, and the frequent category techniques 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 launch agent for tunnels and etc.
- According to the the formula of: it can be divided into water-based concrete release representatives, oil-based concrete release brokers, silicone oil concrete release representatives, etc.
- According to the use effect: it can be divided into ordinary concrete release representatives, simple to remove concrete release representatives, high-gloss concrete release representatives and and so forth.
Features of Concrete release agent
A concrete release agent can also be known as a concrete remoteness agent or mould release lubricant. It is a sort of substance coated on the inner wall of the formwork to play the role of lubricating and separation to ensure that the concrete could be effortlessly detached from the formwork when taking apart the formwork, and the condition 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 effortless release, no pollution of the concrete area, no corrosion of the template, effortless to paint, low cost and etc. However, not all types of concrete release brokers with a array of components made of templates are suitable for different components of the template and different construction problems 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 features:
Good separation efficiency: concrete release agent can form a dense separation motion picture between the formwork and the concrete area, efficiently avoiding the formwork from bonding with the concrete area and facilitating the dismantling.
Great lubrication overall performance: concrete release agent has good lubrication efficiency, which can lower the friction between the formwork and concrete surface, lower the resistance during pouring and improve the construction productivity.
Good anti-adhesion performance: concrete release representatives can successfully prevent the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete area when taking down the formwork.
Great waterproof overall performance: concrete release agent has good waterproof performance, which can efficiently stop moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and improving 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 surface 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 down.
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 development of a reinforced concrete structure, concrete release brokers 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 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 area 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 brokers 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 development projects. By choosing the right type, the correct use method and a reasonable application field, can effectively boost the construction efficiency and quality of the construction project and provide a strong guarantee for the development of the development industry.
