What is actually a concrete release agent?
A concrete release agent is actually a substance applied to the construction design just before the concrete is added in order that the design doesn’t adhere to the concrete surface after pouring, is just not simple to dismantle the mould or impacts the complete of the concrete surface. Its main role within the design and the concrete covering to create a film that will be separated from the two is also called an remoteness agent.
A water-based release agent is an important supplementary inside the release agent and can modify the water-based release agent stream and levelling; its principal attribute is stability to microorganisms and enzymes, which can decrease the price of raw materials. A water-based form release agent is utilized in moulds and goods functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing form goods aren’t just to be able to let the mould release to improve productivity and extend the life of the mould make use of. And can make the item thoroughly clean, size qualified, and lower the creation of scrap, that is an crucial supplementary important to casts and products – concrete additive.
Concrete release agent plays an crucial role inside modern building development; its main role is always to create a layer of isolation film between the template and the concrete surface to ensure that the template doesn’t stick to to the concrete surface in order that it is simpler to take down the form right after putting and to maintain the finish of the concrete area. Here, we will unveil the types, characteristics, usage and use of concrete release agent in detail.
Kinds of concrete release agent
Concrete release brokers can be divided into many sorts based on different grouping methods, and the typical category strategies are the following:
- According to the scope of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete discharge agent for tunnels and so on.
- According to the the composition: it can be divided into water-based concrete release brokers, petroleum-based concrete release agents, silicone oil concrete release brokers, etc.
- According to the the utilization effect: it can be divided into ordinary concrete release representatives, easy-to-remove concrete release agents, high-gloss concrete release representatives and and so forth.
Features of Concrete release agent
A concrete release agent is also known as a concrete isolation agent or mould release lubricant. It is actually a type of substance coated on the inner wall of the formwork to play the function of lubrication and remoteness so that the concrete may be smoothly detached from the formwork when taking down the formwork, and the form of the concrete could be kept intact and undamaged. Compared with the traditional release substance motor oil or waste motor oil, the release agent has the benefits of effortless release, no pollution of the concrete covering, no corrosion of the template, effortless to paint, low price and etc. However, not all types of concrete release representatives with a variety of materials made of templates are suitable for different materials of the template and different construction circumstances 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 following features:
Good separation overall performance: concrete release agent can develop a dense isolation movie between the formwork and the concrete covering, successfully avoiding the formwork from bonding with the concrete area and facilitating the removing.
Excellent lubrication overall performance: concrete release agent has good lubricating performance, which can decrease the chaffing between the formwork and concrete covering, lower the resistance during pouring and enhance the construction efficiency.
Excellent anti-adhesion performance: concrete release brokers can efficiently prevent the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete area when taking apart the formwork.
Excellent waterproof performance: 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.
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 covering.
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 covering 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 construction 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, avoiding 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 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 enhance 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 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 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 type, 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 development of the construction industry.
